| Abstract: | In order to treat the high-concentration Bayer-process digestion solution of diaspore ore,one plant introduced,digested and designed a new process of producing sandy alumina with lst-stage precipitation technique. This paper analyzes and studies the process conditions,and summarizes the production practice. It came to the conclusion that lst-stage-precipitation process have some advantages, such as simple and stable in technological flowsheet,easy in operation and control, high yield, 100% of sandy product, and fully satisfy requirements of aluminum smelting production. |
