Gravity Separation Equipment
Gravity separation, depending on the mineral density and separation of mineral benefication. In addition to have a variety of gravity separation equipment for re-election, must also be the media (air, water, re-solution or re-suspension). Mineral particles subject to gravity, the gravity separation process (if in the centrifugal field is mainly centrifugal force), the mechanical force exerted by the device and the force of the media, the combination of these forces on the different density of mineral particles of different velocity and trajectory , which will ultimately enable them separate from each other.
Ore must be broken before the gravity separation
Particles by density separation of ore before gravity separation must be sufficient crushing and grinding, the dissociation of the useful minerals and gangue minerals, and reduce the large granularity into the process of re-election. The mineral particles must go through the screening and grading of mineral particles is divided into various fractions in order respectively to the different gravity separation machinery. Grain size because of the gravity separation is more narrow, the more it can reduce the influence of particle size sorting, the more we can make the mineral particles by density accurate sorting, gravity separation machinery and improve productivity, and reduce the useful minerals of the mud in the process of sorting .
Ore Gravity Separation Process
Gravity separation process usually consists of washing off the mud, grinding, grading, sorting, and several other job. The structure of its processes, depending on the nature and characteristics of the materials to be elected. In all cases, should the ore optional test of laboratory-scale and semi-industrial scale test, to establish a reasonable gravity beneficiation process.
The nature of the ore is the decisive factor to choose a reasonable process. Depending on the nature of the ore to determine the need for heavy media pre-selection, as well as grinding precision washing, grinding the number of segments, choose the other the number of segments and sediment sorting, rich in ore and whether the re-election operations.
