Jun 09, · Attrition Grinding of Talc. The talc feed, which contained less than 10 percent minus 10micrometer particles, was ground to essentially all pass 10 micrometers in size (fig. 22). The bulk density of the ground products was 11.2 pounds per cubic foot. Electrical energy consumed was 244 kilowatthours per ton of talc feed. Attrition Grinding of

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Michael L. Free, Michael Moats, in Treatise on Process Metallurgy Industrial Processes, 2014 2.7.4.1.2 Copper Ore Leaching by Ore Type. The leaching of copper ores is conducted somewhat differently depending on the minerals present in the ore. Oxide ores containing chrysocolla, malachite, azurite, cuprite, etc., are readily amenable to acid leaching.

The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and groundup limestone) to give a basic pH, pine oil (yes, it comes from trees a byproduct of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a

Extracting copper from other ores. Copper can be extracted from nonsulphide ores by a different process involving three separate stages Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
