Copper extraction
The roasting process is generally undertaken in combination with reverberatory furnaces. In the roaster, the copper concentrate is partially oxidised to produce "calcine". Sulfur dioxide is liberated. The stoichiometry of the reaction is: CuFeS2 + 3 O2 → 2 FeO + 2 CuS + 2 SO2Roasting generally leaves more sulfur in the calcined product (15% in the casEnvironmental impacts need to be partly allocated to by-products of copper mining, such as Molybdeen (Mo) and Silver (Ag).

Transparency on greenhouse gas emissions from mining
Commonly in the copper sector, mines will produce a mineral concentrate (20–40% copper) that is transported to more centralized smelting and refining facilities, Among the copper production processes, electro-refining and electro-winning, both based on electrolysis, are one of the most energy-demanding stages of The use of solar energy in the copper mining processes

Copper Production: How Is Copper Made? ThoughtCo
The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.Coal mining processing plant in Nigeria. This coal mining project is an open pit mine located in Nigeria, announced by mining company Western Goldfields that it has discovered 62,400,000 tonnes of proven reserves of coal deposits worth US$1.2 billion which could be used for the generation of electric power...what are the byproducts of producing lead through mining
