Problems solved by technology

[0004] Second, in the production process, hydrogen sulfide gas severely corrodes the working tank, stirring device, pump, heat exchanger, valve and pipeline, and the service time is short
[0005] Third, hydrogen sulfide gas will come out from the mouth of the operation tank, causing an impact on the operation environment
[0006] Fourth, it affects the continuous and stable production and operation of the pressure leaching process

Abstract

The invention discloses a method for treating zinc sulfide concentrate powder. The method comprises the steps of: a) carrying out size mixing on the zinc sulfide concentrate powder in a first operation tank to obtain slurry; b) adjusting acid liquor in a second operation tank so as to obtain material acid; and c) respectively adding the slurry obtained in the step a) and the material acid obtained in the step b) into an autoclave for pressure leaching. The method for treating the zinc sulfide concentrate powder according to the embodiment of the invention is simple in principle, high in feasibility and remarkable in effects.

Description

technical field [0001] The invention belongs to the field of nonferrous metallurgy, and in particular relates to a method for pressure leaching acid and ore separation into a kettle. Background technique [0002] In the process of pressure acid leaching treatment of zinc sulfide concentrate, it is an important production process to pump the prepared slurry and acid solution into the autoclave. The stable and continuous pumping of ore slurry and acid liquid into the autoclave is one of the important conditions to ensure the continuous production and operation of the autoclave. In the production process, the ore pulp and acid liquid are mixed and prepared in the operation tank before being pumped into the autoclave. Among them there are the following problems: [0003] First, when zinc sulfide concentrate is mixed with acid, it reacts to produce hydrogen sulfide gas. [0004] Second, during the production process, hydrogen sulfide gas severely corrodes the working tanks, st...
