Abstract
This article mainly uses alloy powder(0.82%W,18%Mo,4.62%V,6.68%Fe,6.35%Co,19.08%Ni)as raw material,through a series of leaching experiments,the leaching rates of W,Mo,V,Fe,Co,and Ni are explored to find the optimal leaching parameters.Experimental data shows that,by means of roasting and alkali leaching,W,Mo,and V in the alloy powder can be leached into the solution,thus achieving preliminary separation from Fe,Co,and Ni.When the alloy powder is leached with nitric acid and under the condition of residual acidity of 40～60 g/L,the leaching rates of W,Mo,and V are about 90%,the leaching rates of Co and Ni are about 70%,and the leaching rate of Fe is about 30%.However,the operating environment is not very friendly and is not conducive to industrialization.After the alloy powder is roasted at 600℃ for 4 hours and then leached with sulfuric acid,under the condition of residual acidity of 90～100 g/L,the leaching rates of W,Mo,and V are 80%～85%,and the leaching rates of Fe,Co,and Ni are about 75%,showing a better comprehensive leaching rate.关键词
