Mining and Recycling. Nearly 28 million tonnes of copper are used annually. Copper production begins with the extraction of copper-bearing ores in mining or recycling of scrap metal. The ores are processed into copper concentrate, which can be further treated onsite or sold to a smelter. The figures below represent global production and trade

A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG
