Iron Pigments Through The Ages, Fathi Habashi
Iron Pigments Through The Ages, Fathi Habashi
Fathi Habashi
Naturally occurring iron oxides were used since ancient times as ochre yellow and red pigments. It was only in the 18th century that artificially prepared Prussian blue was discovered. This discovery opened up a new field of chemistry - - cyano compounds.
A Short History Of Uranium, Fathi Habashi
A Short History Of Uranium, Fathi Habashi
Fathi Habashi
Uranium was discovered in 1781 by Klaproth, a pharmacist in Berlin, from the black mineral pitchblende found in Joachimsthal silver mines. Peligot in France in 1841 proved that what Klaproth isolated from pichblende was uranium oxide and not the metal. Uranium salts were used at that time to manufacture coloured glass before the discovery of its radioactivity in 1896. It became in great demand when its decay product radium was found to cure cancer. The discovery if uranium fission in 1939 was the reason for the manufacture of the first atomic bomb.

Altin Metalurji̇si̇nde Yeni̇ Geli̇şmeler, Fathi Habashi
Fathi Habashi
Gold has been extracted from its ores since ancient times. The modern industry, however, was established about hundred years ago when the cyanidation process was invented in 1887. The process was applied successfully for a variety of ores and found wide-spread application in 1970’s for ores containing as low as 1 ppm gold. In the last decade new chemical beneficiation process have been developed to treat ores that are not directly amenable to cyanidation. These involve aqueous oxidation of sulfide minerals containing gold at high temperature and pressure in autoclaves lined with acid-resisting brick.
Mining And Civilization, An Illustrated History, Fathi Habashi
Mining And Civilization, An Illustrated History, Fathi Habashi
Fathi Habashi
Mining and Civilization has been conceived to compliment the author's two books History of Metallurgy and Readings in Historical Metallurgy and to fill a gap in the literature. It is difficult to study the history of metallurgy without studying the history of mining at the same time. Each time the author visits ancient ruins or examines an ancient stone statue he recalls the work of miners who brought the material from a quarry so that the sculptor can create a work of art. History of mining, quarrying, and stone carving is history of civilization.

A Short History Of Mineral Processing, Fathi Habashi
A Short History Of Mineral Processing, Fathi Habashi
Fathi Habashi
Crushing and grinding of ores and their beneficiation by washing away gangue minerals has been practiced since ancient times. Primitive crushing was done by hand pounding the ore with a hard stone then by using metallic hammers. The mortar and pestle was mechanized using a lever and when the size of operations increased in the middle ages, the stamp mill was introduced. The grindstone played an important role in grinding of ores. Panning for gold and hand sorting of minerals were two old methods of separation, now gave way to modern techniques. Flotation started in the middle of the nineteenth …

Schools Of Mines. The Beginnings Of Mining And Metallurgical Education, Fathi Habashi
Schools Of Mines. The Beginnings Of Mining And Metallurgical Education, Fathi Habashi
Fathi Habashi
Education in mining and metallurgy started when Schools of Mines were created. These were usually founded in mining districts, to give instruction not only for future miners and metallurgists, but also for geologists and other technicians needed for the mining and metallurgical industries. Some of these started by private individuals, others were created by the ruler or by the State. Gradually, there became the need to have qualified administrators for the mines and smelters, and for teachers for these schools. As a result, some schools were elevated to academies or became later technical universities, some were closed due to exhaustion …

Hitos En La Historia De La Metalurgia, Fathi Habashi
Fathi Habashi
Up to the Middle Ages, seven metals were only known and used by man. These were gold, silver, copper, iron, lead, tin, and mercury. During the Middle Ages the metalloids arsenic, antimony, and bismuth were isolated as well as zinc that was imported from the East. In the Eighteenth century mineral specimens were continuously supplied and analyzed which resulted in the discovery of about a dozen new metals. With the discovery of electric current at the beginning of the nineteenth century the alkali metals were isolated and these were responsible for the isolation of new metals that were not possible …
