Diamond placer and some primary ores contain a lot of clay minerals, which must be removed before beneficiation. Ore washing is the process of removing clay material from ore, which includes two stages: dispersing clay and separating dispersed clay material from granular material. The commonly used washing equipment includes high-pressure water gun, drum washing machine, trough type ore washing machine, etc.
Grinding is the continuation of the crushing process, the purpose of hydrocyclone is to refer to the mechanical equipment.
The mineral processing process of diamond raw stone generally includes: preparation, roughing and cleaning stages. Screening, ore washing, grinding, hydraulic classification, etc. The purpose is to create good conditions for beneficiation in advance, so that the separation operation can be carried out smoothly and get good results.
There are many places where screening operation is needed in diamond ore dressing. On the one hand, screening can timely separate the ore with appropriate particle size in the crushing stage, creating good conditions for beneficiation in advance, avoiding excessive crushing of ore and reducing power consumption, Hydrocyclone Improving efficiency is also good for protecting crystal! On the other hand, it can prepare for the next step of mineral processing. Screening equipment for screening machine, the most commonly used is vibrating screen, followed by shaking screen. Hydrocyclone for environmental protection and water treatment 。
The main preparation before primary diamond ore dressing. In the crushing stage, on the one hand, the coarse-grained ore should be fully dissociated, on the other hand, the breakage of diamond crystal should be reduced as much as possible. In the process of ore crushing, the requirement of protecting crystal is more strict than that of crushing other ores. There are also hydraulic crusher, jaw crusher and so on.
