High pressure conveying of material with high concentration,high temperature and high corrosion in the process of oxygen pressure leaching

CHEN Long-yi;Changsha Engineering and Research Institute Ltd.of Nonferrous Metallurgy;  
In the process of oxygen pressure leaching of zinc sulphide concentrate, the autoclave feeding has the characteristics of high concentration, high temperature, high pressure and high corrosion. This material, traditionally, is conveyed with diaphragm pump or multistage centrifugal pump. However, years of prodiction practice proves that these two pumps have obvious shortcomings in the actual production. This paper proposes a way of feeding, which will solve the problem about autoclave feeding.
