2. Mining Methods
Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface. Underground mining is used when the copper ore is not near the earth's surface.

Copper Mining and Processing: Processing Copper Ores
Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …

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.

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.
