The insoluble sulphides of iron and copper proved rather neutral as compared with sulphur ground in sand. We then did not expect to obtain a control of aphids by the use of these compounds, but were somewhat unpre- pared to note a marked increase in the woolly aphis where iron sulphide and copper sulphide was used.

Copper Ore Types Sulfides vs. Oxides INN

Copper sulfide ores are typically the most profitable types of copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted

Copper Sulfide Ore- Metalcess

Copper Sulfide Ore. About 80% of the world's copper-from-ore originates in Cu-Fe-S ores, such as chalcopyrite (CuFeS2) and chalcocite (Cu2S). The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu (open pit mines) to 1 or 2% Cu (underground mines).

why was copper one of the first metals to be extracted

Oct 18, 2007 · Gold, silver, and copper were the first metals used because they are found in the elemental state. Most metals found in nature are combined with other elements such as oxygen and sulfur. Since energy is needed to extract metals from these compounds or ores, the ease with which a given metal could be extracted from its ore, along with ore availability, determined when it came into use.
