Product Details

cThe content of gold in the ore is very low, in order to extract the gold, you need to crush and grind ore and adopt mineral processing method for pre-enrichment or separating gold from ore,re-election and floatation method is used in gold mining, re-election method in placer gold production occupies an important position, the flotation method is widely used in rock gold mining .At the present, about 80% of rock gold mining in our country adopt this method, mining technology and equipment level has been more greatly improved.

According to the survey, about 80% of the rock gold mine adopt flotation method to elect gold , most of the output concentrate are sent to non-ferrous smelter to be dealed. As the cyanidation of gold developes gradually and enterprise to improve economic efficiency , reducing loss of concentrate transport, the product structure in recent years has changed greatly, to take a more local processing (of course, the contradiction between the dressing and smelting and pricing and other issues, forcing the mine in place to handle) to promote greater development flotation process, in gold production plays an important role. Usually both flotation and bulk flotation process. Transformation in the process this year and the reagent addition system, there is new progress in flotation recovery has improved markedly. According to more than 40 with gold plant, flotation process indicator survey results show that the sulfide ore flotation rate was 90%, a few up to 95% to 97%; oxide ore rate was 75%; individual reaches 80% ~ 85 %. In recent years, adaptation and innovation in flotation process a lot of research, the effect is obvious, floating stage grinding process, such as heavy a floating joint process, is the development of the main trends in flotation process

As the professional manufacturer of complete sets of mining machinery, such as raymond mill?spiral classifier?raymond mill?rod mill, Henan Hongxing is always doing the best in products and servi
