What is gravity beneficiation equipment?

Gravity beneficiation equipment, referred to as gravity separation, is a beneficiation method that separates mineral deposits according to their different mineral densities. In addition to various re-election equipment, a medium (air, water, heavy liquid or re-suspension) is required for gravity separation. During the re-selection process, the ore particles are subjected to gravity (if it is in the centrifugal force field, it is the centrifugal force), the mechanical force exerted by the equipment and the force of the medium. The combination of these forces makes the ore particles with different densities produce different motion speeds and motion trajectories. , so that they can be separated from each other.

What are the characteristics and uses of gravity beneficiation?

The gravity separation method has the advantages of simple equipment structure and low operating cost, so it can be used when the conditions are suitable.

The main uses of reselection are:

(1) Selection of gold, gold and other precious metals;

(2) Sorting of tungsten and tin ores;

(3) It is widely used in the treatment of placer deposits containing rare metal elements, such as the separation of seaside placer deposits containing zirconium and titanium deposits;

(4) Separation of hematite and limonite;

(5) sorting of manganese ore;

(6) Separation of clean coal and gangue in the coal preparation plant;

(7) Separation of some non-metallic mineral deposits and gangues, such as asbestos, mica, kaolin, sepiolite and diamond;

(8) For non-ferrous metal ores such as copper, lead, and zinc that are mainly treated by flotation, pre-enrichment by gravity separation is also a commonly used method;

(9) Reselect the process of sorting by particle size, such as grading, desliming, etc. Gravity separation is an indispensable operation in almost all concentrators.

At present, the commonly used gravitational gold panning equipment includes gold panning blanket, agitating chute, gold centrifuge, jig machine, shaking table, etc.

The gravity separation process of alluvial gold ore is composed of a series of continuous operations of alluvial gold machinery. The nature of the operation can be divided into three parts: preparation operation, selection operation, and alluvial gold recovery operation. In modern times, to process a mineral, certain conditions must be met before it can be mined.

  (1) Processing capacity: The processing capacity does not mean that the bigger the better, it must meet the actual needs of customers. Therefore, when sand gold machinery manufacturers produce equipment, they have to produce with different processing capabilities.

  (2) At present, many manufacturers on the market produce alluvial gold machinery, and the recovery effect of granular gold is relatively obvious, but the recovery rate of capillary gold is still too low. Therefore, in the process of producing alluvial gold machinery, under the premise of ensuring the recovery of granular gold, the recovery rate of capillary gold should also be considered.

  (3) For gravity gold separation equipment, the energy consumption of the equipment needs to be considered. The equipment consumes too much energy and consumes a lot of electricity. Although it will not cause direct pollution to the environment, it will also indirectly burden the environment.
