Many of the world's top mining companies have come to rely on FEECO for our agglomeration drums; FEECO ore drums are installed in some of the world's largest and most environmentally advanced copper mines. Agglomeration drums are used in the copper heap leaching process to .

Sulphuric dioxide gas is created in smelting copper process and is converted sulphuric acid which is used in some of the smelting processes or sold as a byproduct. Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace.

Nowadays, Western Europe (EU15 and associated countries) in general plays a modest role in the world mineral mining, producing scarcely from 1 to 8% of metalliferous ores and % of hard coal. Of 1872 identified mining sites in the EU, only 917 are reported to be still active, of which 740 sites produce industrial minerals, 119 coal, 45 nonferrous metals and 13 ferrous metals ( BGRM, 2001 ).

Copper mining started in 3000 BC, with already a high standard of extraction. Thousands of workmen were organised to work efficiently with tools that could move three tons of ore at one time. They also were able to dig up to a depth of twenty metres, without any problems.

US History. The largescale mining of copper had its origins in the late 1800's, primarily in the American West. Small mines existed around the country, particularly in the Upper Peninsula of Michigan and in Arizona, but they were able to extract copper only from highgrade ores. The development of efficient flotation processes ¹ around the turn...

In the mining industry, lime products are used to refine and condition metal ores and nonferrous metals such as Copper, Zinc, Nickel, Gold, Silver and Aluminum. For this application, lime products are used in the froth flotation of Copper, Nickel and Zinc and are used in Gold and Silver processing to ensure proper pH in the leaching circuit.
