Mining and Ore Processing Mercury Pollution. Estimated Population at Risk: 1.5 Million. Description. Mining and ore processing occurs throughout the world and consists of extracting minerals, metals, and gems from surrounding earth and ore. Industrial mines vary in size, with some being quite small operations and others very large.
The project will be an open pit mine that will process 127,500 tonnes per day of ore via conventional crushing, grinding and flotation technology to produce 300,000 tonnes of copper per year. First copper production is expected in 2022.
Special bacteria are sometimes used as part of this process. After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal.
