deep sea mining
The most valuable of the marine mineral resources is petroleum. About 15% of the world's oil is produced offshore, and extraction capabilities are advancing. One of the largest environmental impacts of deep sea mining are discharged sediment plumes which disperse with ocean currents and thus may negatively influence the marine ecosystem. Coal deposits known as extensions of land deposits, are mined under the sea floor in Japan and England. (Source: PARCOR / ERIB)

Biringuccio spent much of his life in the service of, or under the patronage of, the Petruccis, one of the leading families of Siena. In his youth, he was able to travel widely in Italy and Germany, observing mining and metallurgical processes at first hand. For example, his visit to the brass-works in Milan was to be the source of the detailed description in Pirotechnia, published alter his death. He held various appointments in charge of mines or other concerns, such as the Siena mint, under the patronage of the Petruccis. During two periods of exile, while the Petrucci fortunes were in eclipse, he engaged in military activities such as the casting of cannon. That included the great culverin of Florence cast in 1529, also described in the Pirotechnia. In December 1534 Pope Paul III offered him the post of Director of the papal foundry and munitions. He did not take up the post until 1536, but he died the following year.

P irotechnia, which made Biringuccio famous, was published in Venice in 1540, three years after his death. The word "pirotechnia" had a wider meaning than that of fireworks, extending to the action of fire on various substances and including distillation and the preparation of acids. While owing something to earlier written sources, the book is substantially based on a lifetime of practical experience of mining and metalworking, including smelting, casting and alloying, and evidence in the book suggests that it was written between 1530 and 1535. Curzio Navo brought out the second and third editions in 1550 and 1559, as well as a Latin edition. A fourth edition was also printed in 1559. The appearance of four editions in such a short time testifies to the popularity and usefulness of the work.

John Coster, son of an iron-forge manager in the Forest of Dean, by the age of 38 was at Bristol, where he was "chief agent and sharer therein" in the new lead-smelting methods using coal fuel. In 1685 the work, under Sir Clement Clerke, was abandoned because of patent rights claimed by Lord Grandison, who financed of earlier attempts. Clerke's business turned to the coal-fired smelting of copper under Coster, later acknowledged as responsible for the subsequent success through using an improved reverberatory furnace which separated coal fume from the ores being smelted. The new technique, applicable also to lead and tin smelting, revitalized copper production and provided a basis for new British industry in both copper and brass manufacture during the following century. Coster went on to manage a copper-smelting works, and by the 1690s was supplying Esher copper-and brass-works in Surrey from his Redbrook, Gloucestershire, works on the River Wye. In the next decade he extended his activities to Cornish copper mining, buying ore and organizing ore sales, and supplying the four major copper and brass companies which by then had become established. He also made copper goods in additional water-powered rolling and hammer mills acquired in the Bristol area. Coster was ably assisted by three sons; of these, John and Robert were mainly active in Cornwall. In 1714 the younger John, with his father, patented an "engine for drawing water out of deep mines". The eldest son, Thomas, was more involved at Redbrook, in South Wales and the Bristol area. A few years after the death of his father, Thomas became partner in the brass company of Bristol and sold them the Redbrook site. He became Member of Parliament for Bristol and, by then the only surviving son, planned a large new smelting works at White Rock, Swansea, South Wales, before his death in 1734. Partners outside the family continued the business under a new name.

In 1842, as a graduate of the Ecole des Mines in Liège, he became a member of the Belgian Corps Royal des Mines, which he left ten years later as Chief Engineer. By that time he had become decisively influential in the Société Anglo-Belge des Mines du Rhin, founded in 1848. After it became the Gelsenkirchen-based Bergwerkgesellschaft Dahlbusch in 1873, he became President of its Board of Directors and remained in this position until his death. Thanks to his outstanding technical and financial abilities, the company developed into one of the largest in the Ruhr coal district.

When K.G. Kind practised his shaft-boring for the company in the early 1850s but did not overcome the difficulty of making the bottom of the bore-hole watertight, Chaudron joined forces with him to solve the problem and constructed a rotary heading which was made watertight with a box stuffed with moss; rings of iron tubing were placed on this as the sinking progressed, effectively blocking off the aquiferous strata as a result of the hydrostatic pressure which helped support the weight of the tubing until it was secured permanently. The Kind-Chaudron system of boring shafts in the full section marked an important advance upon existing methods, and was completely applied for the first time at a coalmine near Mons, Belgium, in 1854–6. In Brussels Chaudron and Kind founded the Société de Fonçage par le Procédé Kind et Chaudron in 1854, and Chaudron was granted a patent the next year. Foreign patents followed and the Kind-Chaudron system was the one most frequently applied in the latter part of the nineteenth century. Altogether, under Chaudron's control, there were more than eighty shafts sunk in wet strata in Germany, Belgium, France and England.

The son of a barber-surgeon who deserted his family to serve in the Swedish army, Nobel showed little interest in academic pursuits as a child and was sent to sea at the age of 16, but jumped ship in Egypt and was eventually employed as an architect by the pasha. Returning to Sweden, he won a scholarship to the Stockholm School of Architecture, where he studied from 1821 to 1825 and was awarded a number of prizes. His interest then leaned towards mechanical matters and he transferred to the Stockholm School of Engineering. Designs for linen-finishing machines won him a prize there, and he also patented a means of transforming rotary into reciprocating movement. He then entered the real-estate business and was successful until a fire in 1833 destroyed his house and everything he owned. By this time he had married and had two sons, with a third, Alfred (of Nobel Prize fame; see Alfred Nobel), on the way. Moving to more modest quarters on the outskirts of Stockholm, Immanuel resumed his inventions, concentrating largely on India rubber, which he applied to surgical instruments and military equipment, including a rubber knapsack.

It was talk of plans to construct a canal at Suez that first excited his interest in explosives. He saw them as a means of making mining more efficient and began to experiment in his backyard. However, this made him unpopular with his neighbours, and the city authorities ordered him to cease his investigations. By this time he was deeply in debt and in 1837 moved to Finland, leaving his family in Stockholm. He hoped to interest the Russians in land and sea mines and, after some four years, succeeded in obtaining financial backing from the Ministry of War, enabling him to set up a foundry and arms factory in St Petersburg and to bring his family over. By 1850 he was clear of debt in Sweden and had begun to acquire a high reputation as an inventor and industrialist. His invention of the horned contact mine was to be the basic pattern of the sea mine for almost the next 100 years, but he also created and manufactured a central-heating system based on hot-water pipes. His three sons, Ludwig, Robert and Alfred, had now joined him in his business, but even so the outbreak of war with Britain and France in the Crimea placed severe pressures on him. The Russians looked to him to convert their navy from sail to steam, even though he had no experience in naval propulsion, but the aftermath of the Crimean War brought financial ruin once more to Immanuel. Amongst the reforms brought in by Tsar Alexander II was a reliance on imports to equip the armed forces, so all domestic arms contracts were abruptly cancelled, including those being undertaken by Nobel. Unable to raise money from the banks, Immanuel was forced to declare himself bankrupt and leave Russia for his native Sweden. Nobel then reverted to his study of explosives, particularly of how to adapt the then highly unstable nitroglycerine, which had first been developed by Ascanio Sobrero in 1847, for blasting and mining. Nobel believed that this could be done by mixing it with gunpowder, but could not establish the right proportions. His son Alfred pursued the matter semi-independently and eventually evolved the principle of the primary charge (and through it created the blasting cap), having taken out a patent for a nitroglycerine product in his own name; the eventual result of this was called dynamite. Father and son eventually fell out over Alfred's independent line, but worse was to follow. In September 1864 Immanuel's youngest son, Oscar, then studying chemistry at Uppsala University, was killed in an explosion in Alfred's laboratory: Immanuel suffered a stroke, but this only temporarily incapacitated him, and he continued to put forward new ideas. These included making timber a more flexible material through gluing crossed veneers under pressure and bending waste timber under steam, a concept which eventually came to fruition in the form of plywood.

In 1868 Immanuel and Alfred were jointly awarded the prestigious Letterstedt Prize for their work on explosives, but Alfred never for-gave his father for retaining the medal without offering it to him.

A scholar of the Mining Academy in Freiberg, who in his dissertation dealt with the fineness of coal dust, Rammler started experiments in 1925 relating to firing this material. In the USA this process, based on coal, had turned out to be very effective in large boiler furnaces. Rammler endeavoured to apply the process to lignite and pursued general research work on various thermochemical problems as well as methods of grinding and classifying. As producing power from lignite was of specific interest for the young Soviet Union, with its large demand from its new power stations and its as-yet unexploited lignite deposits, he soon came into contact with the Soviet authorities. In his laboratory in Dresden, which he had bought from the freelance metallurgist Paul Otto Rosin after his emigration and under whom he had been working since he left the Academy, he continued his studies in refining coal and soon gained an international reputation. He opened up means of producing coke from lignite for use in metallurgical processes.

His later work was of utmost importance after the Second World War when several countries in Eastern Europe, especially East Germany with its large lignite deposits, established their own iron and steel industries. Accordingly, the Soviet administration supported his experiments vigorously after he joined Karl Kegel's Institute for Briquetting in Freiberg in 1945. Through his numerous books and articles, he became the internationally leading expert on refining lignite and Kegel's successor as head of the Institute and Professor at the Bergakademie. Six years later, he produced for the first time high-temperature coke from lignite low in ash and sulphur for smelting in low-shaft furnaces. Rammler was widely honoured and contributed decisively to the industrial development of his country; he demonstrated new technological processes when, under austere conditions, economical and ecological considerations were neglected.

Agricola was a physician, scientist and metallurgist of note and it was this which led to the publication of De Re Metallica. He studied at Leipzig University and between 1518 and 1522 he was a school teacher in Zwickau. Eventually he settled as a physician in Chemnitz. Later he continued his medical practice at Joachimstal in the Erzgebirge. This town was newly built to serve the mining community in what was at the time the most important ore-mining field in both Germany and Europe.

As a physician in the sixteenth century he would naturally have been concerned with the development of medicines, which would have led him to research the medical properties of ores and base metals. He studied the mineralogy of his area, and the mines, and the miners who were working there. He wrote several books in Latin on geology and mineralogy. His important work during that period was a glossary of mineralogical and mining terms in both Latin and German. It is, however, De Re Metallica for which he is best known. This large volume contains twelve books which deal with mining and metallurgy, including an account of glassmaking. Whilst one can understand the text of this book very easily, the quality of the illustrative woodcuts should not be neglected. These illustrations detail the mines, furnaces, forges and the plant associated with them, unfortunately the name of the artist is unknown. The importance of the work lies in the fact that it is an assemblage of information on all the methods and practices current at that time. The book was clearly intended as a textbook of mining and mineralogy and as such it would have been brought to England by German engineers when they were employed by the Mines Royal in the Keswick area in the late sixteenth century. In addition to his studies in preparation for De Re Metallica, Agricola was an "adventurer" holding shares in the Gottesgab mine in the Erzegebirge.

William Humfrey, goldsmith of the parish of St Vedast, was appointed Assay Master of the Royal Mint in 1561. At the Tower of London he assumed responsibility for the weight of silver and for production standards at a time of intense activity in recoining the debased coinage of the realm. Separation of copper from the debased silver involved liquation techniques which enabled purification of the recovered silver and copper. German co-operation in introducing these methods to England developed their interest in English copper mining, resulting in the formation of the Mines Royal Company. Shareholders in this government-led monopoly included Humfrey, whose assay of Keswick copper ore, mined with German expertise, was bitterly disputed. As a result of this dispute, Humfrey promoted the formation of a smaller monopoly, the Company of Mineral Battery Works, with plans to mine lead and especially the zinc carbonate ore, calamine, using it to introduce brassmaking and wire manufacture into England. Humfrey acquired technical assistance from further skilled German immigrants, relying particularly on Christopher Schutz of Annaberg in Saxony, who claimed experience in such matters. However, the brassmaking project set up at Tintern was abandoned by 1569 after failure to make a brass suitable for manufacturing purposes. The works changed its production to iron wire. Humfrey had meanwhile been under suspicion of embezzlement at the Tower in connection with his work there. He died intestate while involved in litigation regarding infringement of rights and privileges claimed from his introduction of new techniques in later lead-mining activities under the auspices of the Company of Mineral and Battery Works.
