–Screening. Screening the cleaned alluvial gold ore to remove large pieces of gold-free stones will help improve the gold beneficiation efficiency. –Gravity separation. Coarse gold concentrates are available in the process, so the gravity separation process directly affects the results of the entire placer gold beneficiation. –Concentration.
Crushing & screening: In the crushing and screening stage of lithium ore, a three-stage and one closed-circuit crushing and screening process, or a two-stage and one closed-circuit crushing and screening process can be adopted.Specifically, it is necessary to refer to the particle size of the raw ore and equip a reasonable lithium ore crushing process.
coal beneficiation has some characteristics similar to the bubbling fluidized beds utilized in chemical engineering, but also some essential differences. The dense gas-solid fluidized bed separator with high densities needs to provide a favourable density distri-bution environment for coal beneficiation through some special flow properties and

Coal beneficiation is one of the most effective methods for removing minerals (such as gangues and pyrite) and pollutants (such as sulfur) before the burning of coal. In general, the beneficiation process of low rank coals is more difficult to achieve than that of bituminous and/or anthracite coals.

Easiest to beneficiate are haematite ores (bottom part of the picture). In simplified terms, the process steps comprise "Mine-Crush-Screen-Sell" and are also described as DSO process (DSO = high-grade direct shipping ore). On account of the low process costs, DSO ores with iron content of 58 % are produced.
