ABOUT PROCESSING OF ZINC CAKE
The article describes the technology for processing of zinc cake and given the shortcomings of existing technology. The results of the study heat treatment and sulfuric acid leaching process heat treatment product which is intended to additional recovery of zinc and a number of non-ferrous metals. Considered various schemes heat treatment leaching of zinc cake. The influence of various factors (temperature, acid concentration, the duration of leaching, the pulp density, etc.) on the degree of extraction of metals in the solution found optimal conditions for the meeting.
