DEVELOPMENTS AND PROSPECTS OF EXTRACTING POTASH FROM INSOLUBLE POTASH ORES

Wang Wanjin Bai Zhimin Ma Hongwen (Department of Materials Science,China University of Geosciences,Beijing,100083)  
The distribution of the potash salt resources is unbalanced in the world.It is very poor in China,but the insoluble potash ores are considerably rich.Extracting potash from those kinds ores is an effectual way to solve the problem of potash fertilizer shortage.The developments in extracting potash from insoluble potash ores are reviewed in this paper,and the technical difficulties and industrial prospects are discussed briefly.
