Gravity beneficiation is one of the most popular of several beneficiation, the main deal with the density difference between the larger materials. It is a coal sorting the most important method, but also choose the traditional methods of the other gold, tin, tungsten and other metal ore, titanium, zirconium, hafnium, vanadium, niobium, tantalum, molybdenum and other rare metal ore is also very common. Gravity beneficiation is also used for sorting iron ore and manganese ore, is also used to deal with some non-metallic ore, such as asbestos, diamond, kaolin. Flotation processing non-ferrous metals such as copper, lead, zinc ore, gravity separation method of pre-sorting to remove coarse gangue or wall rock to reach the initial enrichment. In addition, the gravity beneficiation method can be applied to dehydration, grading, concentrate, dust, and other operations. These processes link is an integral part of all concentrator and coal preparation plant.

The raw material of processing equipment can be broken by crusher, after they is up to reasonable fineness, they will be put into ball mill through conveyor belt and feeder. The ball mill can smash and grinding the minerals. The ore materials ground by ball mill will develop into the next fine procedure: grading. Spiral classifier depends on the theory, principle is that the different proportion of solid particles has the different speed in the liquid, After ore mining is exploited, we need to classify the mixture of minerals. The mineral mixture classified will be into magnetic separation machine, because of the different magnetized coefficient of all kinds of minerals, the magnetic material will be separated in the mixture with the aid of the magnetic force and mechanical force. The dressing material will be into flotation machine through the mixing canister. According to different mineral properties, we need add the different drugs to make the mineral be separated. Because the minerals separated contains a large number of moisture content, we need concentrator to preliminary concentrate, and then use the rotary dryer to make the material dry, at last we can get the dried minerals.

Beneficiation process should be efficient and simple as far as possible, such as grasping the development of energy-saving equipment to achieve the best effect in the most appropriate process. In a concentrator, the largest cost proportion are: investment on crushing and grinding equipments, production costs, energy consumption and steel consumption, so the selection and operation management of crushing machine and grinding equipment is largely determine the economic benefits of mineral processing plant.
