Copper Mining and Processing Processing of Copper Ores

Copper Mining and Processing Processing of Copper Ores

Copper mining is usually performed using openpit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.

The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

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 directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

There are four main mining methods underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. Insitu mining
