heap leaching: Generally, an industrial mining process in which a valuable metal is extracted from a heap, or pile, of crushed ore. For copper oxide ore, heap leaching is the first stage in the process of hydrometallurgy, in which a chemical solution is applied to a heap of crushed ore, through which it percolates, dissolving the copper.Web

Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. Mineral processing is conducted at the site of the mine and is a highly mechanical process, with oversight from a central control room.Web

Dilution rate: In the process of ore mining, due to the mixing of waste rock and gangue, loss of high-grade ore, dissolution or loss of some useful components, etc., the grade of the mined ore is lower than the geological grade of the ore in the industrial reserves calculated before mining. This phenomenon is called ore dilution.Web
