Method for preparing alkali-slag cement retarder through jarosite slag
The invention discloses a method for preparing an alkali-slag cement retarder through jarosite slag. The method sequentially comprises the steps that a dispersing agent, the jarosite slag and an oxidizing agent are added into water and evenly stirred, lime is added, even stirring is carried out, and the mixture stands to achieve solid-liquid separation; solid phases obtained after solid-liquid separation are dried, and the alkali-slag cement retarder is obtained; an extraction agent is added into liquid phases obtained after solid-phase separation, valuable metal silver is recycled, and extraction liquid is recycled as water used in the first step. The method is simple and good in effect and has a significant benefit.
