from copper ore to finished products
A comparison of copper use in China and India as a proxy
Assumptions: The production of copper alloy products was calculated by subtracting the copper semi-finished production from total production of semi-finished products. The numbers were multiplied by 65% to determine % of Cu content in copper alloy semi-finished products [for China]. No alloys were reported [for India]. ManufacturingBeaumont, C. & Musingwini, C.

Direct Process for Wire Production from Sulfide
Currently, the supply chain from copper mining to copper wire production is . highly energy intensive. The smelting process requires pyrometallurgy to transform copper sulfides into sulfuric acid and a solid copper product (cathode). Oxidation removes molten iron (as FeO) and sulfur dioxide (SO. 2) gas from the ore. Several reactors upstreamFor example, the most-favoured-nation (MFN) import duty on bauxite is 2.5%, whereas, on aluminium metal and its products, the duties range from 3.9 to 9.8%.

From Ore to Finished Product Copper
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.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.Copper Production: How Is Copper Made? ThoughtCo
