Like vanadium, chromium hardens steel, so it is frequently used in alloys, especially stainless steel. Chromium compounds are all strongly colored, and this characteristic gives chromium its name. Chromium compounds are used as a yellow coloring agent in the textiles industry. It also is used in the tanning of leather.
Sep 25, 2014· Cuba is an important nickel and cobalt producer, ranking sixth in the world in terms of nickel and (fluctuatingly) accounts for 8% of the world''s cobalt production. The nickel resource comes from extensive laterite deposits that are considered among the largest reserves in the world. Cuba ranks with Canada, Russia, Australia and New Caledonia.
The abundance of chromite ore deposits in Camagüey province of Cuba has attracted the attention of prospectors since the early 20th century and helped Cuba reach prominence in the export of chromite during the Second World War. Medium to large deposits of refractory chromite .
Crystalline blebs of Chromite in Serpentine from Wood''s Chrome Mine, Texas, Lancaster Co, Pennsylvania (Dana locale). Large beds of massive Chromite, which lay between beds of Serpentine rock, were mined at this locality beginning in the mid 19th century.
Prior to the Cuban revolution in, the US operated several refineries in Cuba, and between 1916 and 1940 imported more than 720,000 tonnes chromite ore from the country. After the revolution and the US embargo, Cuba instead formed a series of trade agreements with the Union of Soviet Socialist Republics (USSR).
Nickel, chromite, and copper mines are important to Cuba, and beds of laterite (an iron ore) in the Holguín region have considerable potential. Nickel ore, which also yields cobalt, is processed in several large plants, and Cuba is a world leader in nickel production. There are also major reserves of magnetite and manganese and lesser amounts ...
