Abstract
The utility model belongs to the technical field of gold concentration, and particularly relates to a novel gold concentration device. Raw ores are crushed via a high-efficient high-pressure roller mill, crushed products are classified by means of screening, final products generated after screening are milled via a ball mill and a classification mechanism which form a closed loop, differential floatation is performed on the classified overflowing products, rough floatation concentrates are cleaned by three times to generate final concentrates, and rough tailings are scavenged twice to obtain final tail floatation concentrates to perform roughing floatation and recycle. Compared with the prior art, by adopting the high-pressure roller mill, the novel gold concentration device has the advantages of high crushing efficiency, high fine fraction content in final crushed products and strong crushing ability. The fine fraction content of the final crushed products is high so as to lower ore milling energy consumption, and predicated comprehensive energy consumption of crushing and milling operation of the high-pressure roller mill can be reduced by 20% to 30%.
