Mineral Processing. In initial ore treatment fans are used for washing or percolation in ore leaching to increase airflows, and fans and blowers are used to provide air for flotation cells. Smelting of concentrated base metal ores (copper, lead, zinc) is a process in which fans and the turbo compressors provide air for the reactions.

Early mineral processing typically involved manual labor, such as striking ore with hammers to break it open. This process of separating minerals from ore by hand was known as spalling. Similar processes were developed during the 10th century that mechanized the use of hammers to break the ore.

Processing. The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Finegrained iron ore is processed into coarsegrained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon.

Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the nonmetallic material of the ore in a process called ''beneficiation.'' Milling is one of the most costly parts of beneficiation, and results in very fine particles that

CARBON ADSORPTION RECOVERY. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution. The CIL process is frequently used when native carbon is present in the gold ore. This native carbon will adsorb the leached gold and prevent its recovery.
Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

The overall process can be broken into four major steps: 1. Finding a Deposit. When a mining company is interested in opening a new mine, they begin with one of two steps. If the company already knows the ore content of a region (see location of deposits page), they will begin sampling and conducting feasibility studies. However, if they have no prior knowledge of a potential deposit, they will begin mineral .
