Experimental Study on Alkali Leaching of a White Smoke Dust
-
Abstract
White dust is the solid by-product produced in the process of copper smelting,containing Cu,Zn,Pb,Au,Ag,Bi and other valuable elements,and it is a potential resource.Because alkaline leaching arsenic removal has such advantages as good working environment,wide application,low energy consumption and rich technical means,it gains better industrial prospect and is expected to achieve the comprehensive utilization of valuable elements in white dust.According to the existing condition of main elements in white dust in the process of copper smehing,using sodium hydrate to make arsenic removal can achieve the goal that the removal rate of arsenic in As leaching solution is about 98 %,the content of As in the slag less than 1%,and the content of As in Cu,Pb,Zn and other valuable metals can be effectively separated.The use of lime can remove As out of the alkaline infiltration and can achieve the recycling of remnant alkali of alkali leaching. -
