摘要

In this paper two optional production processes are presented for reasonable utilization of primary sylvinite in Qinghai province, China. The two kinds of products as chlorine-free potash fertilizers; potassium sulphate or potassium magnesium sulphate can be obtained.In the course of potassium sulphate production, using primary sylvinite from Qinghai salt lake as raw material with impurities such as sodium chloride and insoluble in primary sylvinite, it must be prepared by flotation before being converted into potassium sulphate. This final product has found wide use in tobacco industry in China.However, in some cases Chinese farmers would rather buy the fertilizer of potassium magnesium sulphate than high quality of potassium sulphate. With flotation process which is a little different from above mentioned, the potassium magnesium sulphate fertilizer may be produced by washing one of the flotation concentrate presented as picromerite, while another concentrate containing potassium chloride is treated as by-product.
