Iron ore mining is the process of extracting iron from its natural form, which is found in rocks and minerals. The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can ...

Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.

Gold milling, which is also known as fine grinding, pulverising or comminution, is a grinding process that reduces materials into a powder or finer sized particles. Milling is used to recover the maximum amount of gold from the ore by finely grinding it so that gold particles can be removed through gravity separation and/or chemical extraction.
