The production line of flotation &cyaniding of Xinhai mainly composed of flotation machine, leaching agitation tank, zinc powder replacement equipment, washing thickener of 2 or 3 layers. The production line characterized by high efficiency and capacity, low energy consumption and reasonable economic costs
To improve the recovery rate of the silver flotation, xinhai developed the mineral processing in three methods. Firstly, due to the thickness features of the silver particles to dissociate silver totally to improve the recovery rate. Secondly, use neutral or weak alkalinity pump as well as the sodium carbonate as regulators to improve the floatability of silver. Thirdly, sodium n-butyl xanthate and sodium butyl aerofloat are mix-used to enhance the collecting ability to the silver.Similar to other mineral processing methods, silver flotation process also need to prepare materials bef separation. That is to say, the ore should be grinded and classified to suit the flotation fineness. Xinhai also adopts the multi-layer thickener to dewater in three stages, and exchange the cyaniding process of one leaching and one dewatering into two of each, which highly improving the recovery rate of the silver. Xinhai also use cyaniding to process Hydrogen-containing wastewater and to recover sodium cyanide, which proves to be a good method to solve the wastewater pollute. The alloy gold can adopt electrolyte equipment to dissociate silver, and get gold and silver ingot to improve the economic efficiency.
