Experimental Study on Optimization of Potash Positive Flotation Process in a Certain Company
The cold decomposition-positive flotation method of the second workshop of Qing-hai Yanyun Potash Co.,Ltd.to produce potassium chloride has problems such as low recovery rate of potassium salt decomposition and high potassium chloride content of tail salt.This article found through process investigation and flotation experiments that these problems are caused by excessive decomposition water during the production process,poor separation efficiency during flotation and excessive washing water volume.According to the process investigation and test results,reasonable suggestions were put forward from the four processes of decomposition process,flotation process,washing and filtration process and drying and packaging process.
