Copper extraction - Wikipedia

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).

Small Ball Mills for Sale - 911Metallurgist

Ball mills of greater length are termed “tube mills,” and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as “pebble mills.’’ In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 um.


The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
