Chalcocite Psm Fossil Wood Malachite Azurite
· Nacimiento Mine, San Pablo, Sandoval County, New Mexico, United States of America A nice piece of fossil wood in sandstone, the wood replaced by black chalcocite which is partly turning to green malachite. Also some blue azurite lines in the encasing sandstone. Those fossilized logs were used as ore, most of them melted down for the copper. Nowadays this material is very scarce and .

minerals have been chalcocite, covellite, bornite, which are all copper and copperiron sulphides while enargite, tetrahedride and tenantite are copper, antimony/arsenic sulphides. Apart from these, oxide and carbonate ores of copper such as cuprite, tenorite, malachite and azurite also occur in minor quantities. The copper minerals

smelting chalcocite malachite
smelting chalcocite malachite vrystaatboranklub. The oxidized ores, such as cuprite and tenorite, can be reduced directly to metallic copper by heating with carbon in a furnace, but the sulfide ores, such as chalcopyrite and chalcocite, require a more complex treatment in which lowgrade ores have to be enriched before smelting begins.
Malachite
Malachite is the another copper carbonate hydroxide mineral with chemical formula [Cu 2 CO 3 (OH) 2] formed by the weathering of copper orebodies in the color is bright green (Fig. ) with light green hardness and specific gravity varies between –, and –, respectively. The mineral in the purest form contains % Cu.
The Smelting of Sulfide Ores of Copper in Preconquest Peru
solved question of preconquest smelting, but shows that mining techniques were more advanced than generally believed. More important, it indies that the man who made it had somehow hit upon the relatively complied processes involved in smelting sulfide ores of copper, such as chalcocite (Cu2S), covellite (CuS), and the mixed sulfides of ...

Copper Mining and Extraction Sulfide Ores
The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ 2 (slag) This is .
Extraction – Deutsches Kupferinstitut
In subsequent smelting, copper concentrates are mainly processed by smelting metallurgy (pyrometallurgy), while oxide copper ores are processed by wet metallurgy (hydrometallurgy). Due to the high investment costs, smelting metallurgical processing is only worthwhile for high capacities of over 50,000 t of copper per year.
