In Phalaborwa in Limpopo province, copper ore is mined using open pit mining. This open pit is one of the world's largest open pit mines. It is 2 km across and the largest man-made hole in Africa. ... This is a very energy-intensive step in the mining industry, and one of the reasons why mining is so expensive.

2013-5-21  Open pit copper mining plants usually comprise two major components, the open pit mining operation and the copper ore enrichment plant. An open pit copper mine is an excavation or graze made into the sur-face of the ground for the purpose of extracting ore. A series of data obtained by a transportation control

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...

Copper is used to control fungi and marine borers, arsenic to control insects and some copper-resistant fungi, and chromium to fix the copper and arsenic in the wood. (Report on Copper, Chromium and Arsenic (CCA) Treated Timber by Deborah Read, 2003) 6 Copper mining
