Overview
An average New Ingerbelle copper process recovery of 88.5%, gold process recovery of 71%, and silver process recovery of 65% is based on geo-metallurgical domains, historical recoveries, and recent testwork. Average bulk density is 2.78 t/m3. Stockpile tonnes and grade are based on production grade control process.

copper processing
The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

Copper Mining Equipment
18/05/2022From a general perspective, copper mining mainly includes three parts. First, we use underground lhd mining equipment to mine copper ore. Then, we use the underground lhd to transport the copper ore to the processing place. Finally, using large machines, the copper ore is smelted and purified.

The effects of copper mining on local people and ecology
25/08/2017They replied that copper mining requires the use of large amounts of suphuric acid to extract the copper from the ores. Especially in high rainfall areas, this creates the phenomenon of acid mists and acid rains, that can fall many miles from the mine and smelters, causing damage to buildings, crops and most important, human health.
