COPPER Copper production - Repository

Copper concentrators typically treat up to 100 000 t of ore per day. They are lo ed directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages.

Grinding Mill - an overview ScienceDirect Topics

Although in its initial uses it was relatively energy inefficient, the lower capital and operating costs saw rapid adoption of the technology. However, many of the early plants experienced difficulties because in practice relatively few ores are suitable for autogenous grinding, because of the buildup in the circuit of intermediate sized called critical-sized particles that did not break in ...

Flexible milling and grinding solutions that last FLSmidth

For the mining industry, our semi-autogenous SAG grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous AG grinding mills involve no grinding media as the ore itself acts as the grinding media.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...
