Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of Most copper ores contain only a small percentage of copper. The modern froth flotation process was independently invented the early 1900s in The copper ore is crushed and ground to a size such that an acceptably high
