Therefore 80% above iron minerals need magnetic separation. Manganese minerals such as psilomelane, pyrolusite, and Rhodochrosite also have weak magnetic properties and are usually recovered by magnetic separation. Ilmenite, Wolframite, Monazite, and niobium-tantalite are all weakly magnetic minerals. Also used magnetic separation.

When the ore is in a larger block of rock diamond minerals and is a high-hardness metal ore, if precious diamonds need to be extracted from the ore, crushing equipment is used to reduce the particle size. Usually, jaw crushers, impact crushers and cone crushers are mainly used, each with unique features tailored to the hardness of diamond ore.

As for most middle-sized and large-scale magnetic separation plants, when the grain size is above 0.2-0.3mm, one-stage magnetic separation is chosen; when the grain size is below 0.2-0.3mm, two-stage magnetic separation is chosen. If coarse grinding is able to separate qualified tailings, the phased magnetic separation method is taken.

About Limestone. Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite or aragonite. It is a kind of stone widely found in nature. Limestone can be directly processed into stone using crushing equipment and fired into quicklime. Quicklime absorbs moisture or adds water to become hydrated lime.

This section looks at methods to get very large rocks crushed and ground until it is as fine as powder. The first concept that needs to come across here is that minerals are inside rocks and by crushing rocks, the minerals are exposed at the surface of the rock fragment. Only then can chemicals be used to extract the mineral.
