The purpose of the alluvial gold ore processing process is to recover gold and its associated heavy minerals from the vein minerals as far as possible, and then use the combined operation of re-election, amalgamation, magnetic separation and electrostatic separation to separate the gold and various associated heavy minerals from each other, so as to achieve the purpose of comprehensive recovery.
The alluvial gold beneficiation process is mainly used in seaside alluvial, riverside alluvial or alluvial ores. The alluvial gold beneficiation process includes cracking, screening, desliming stages, separation, etc.
Alluvial Gold Washing
Many alluvial gold ores contain agglomerates of mud, some of which are larger than 100mm in size, which, if not broken down, will be removed with the waste rock in the screening process, resulting in gold loss. In addition, vibrating screens and trommel screens are commonly used as screening equipment, both have a long service life and a large processing capacity.
Alluvial gold ore sorting
Practice has proved that the gravity separation method is an effective and economic treatment method for alluvial gold ores. Due to the different particle size composition of gold in alluvial gold ore, different alluvial gold ore dressing equipment for processing the effective size limit of the material is also different, so a reasonable alluvial gold sorting process should be used for the joint operation of several different gravity separation equipment.
Jigger/shaker gravity separation
The XKJ Group jigger with conical slide valve reduces the failure rate by 80%, consumes less energy, enables the sorting needs of different materials and increases the processing capacity by more than 35%. In addition to this, the XKJ Group jigger uses advanced frequency control technology for easy operation and management; it has a small footprint and a large processing capacity per unit area. The XKJ Group has improved on the traditional 6s shaker by adopting a cam lever type bed head, where the stroke can be adjusted by changing the position of the sliding head on the shaker arm and the stroke is adjusted by a smooth motor pulley. The advantages include easy adjustment of the stroke; smooth running of the shaking bed; compact construction; and lower energy consumption.
The process flow is simple, the cost of the alluvial gold ore beneficiation equipment is low and easy to operate. In addition, the process has the characteristics of environmental protection and can discharge tailings directly, which greatly reduces the civil construction investment of the whole beneficiation plant project.
