In response to the requirements of the country to develop mineral environmental protection and selection technology, Beijing Boda Technology Research Institute has successfully developed a new non-polluting vibration centrifugal gold selection machine by introducing international technology, which has been promoted and applied nationwide.
It is understood that there are many methods for selecting gold from ore. Commonly used methods include amalgamation, flotation, and cyanidation. However, toxic, harmful mercury or highly toxic chemicals should be used in the production process of amalgamation, flotation, and cyanidation. These substances will cause great damage to the atmospheric environment, water quality, soil, vegetation, and humans and animals. harm.
The centrifugal gravity gold selection method separates the gold particles and the stone material by the centrifugal force according to the difference of the density of gold (19.3 g/m3) and the density of the ore (about 2.5 g/m3). Under the action of lateral centrifugal force, the new vibrating centrifugal gold separator innovatively adds tens of thousands of vibration forces to force the gold particles and stone to separate, so that the gold particles in the ore are efficiently recovered, thus expanding the centrifugal gravity gold selection method. Scope of application.
The new vibrating centrifugal gold separator can screen out more gold particles in the mineral material. When selecting gold particles of 15 microns or more, the performance is at least 10% higher than that of the old-fashioned re-election machine, the enrichment ratio is up to 10000:1, and the recovery rate is up to 80. %~96%, and the selection cost is low.
The new vibrating centrifugal gold separator is suitable for the gold selection of rock gold, gold and polymetallic ore. It is also the first choice for refractory gold ore, such as arsenic, sulfur and carbon. It can also be selected from tailings.
