Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Copper Ore Mining: Exploration, Extraction, and Processing
For example, to smelt 1 ton of cast iron, it is necessary to extract on average 2-3 tons of ore, and to obtain 1 ton of copper, mining and processing plants need to process more than 200 tons of ore. Therefore, to ensure the specified production volumes, it is difficult to imagine the figure representing the amount of ore processed per year.
