浙江省溶性钾矿资源开发利用研究

A Study on the Exploitation of Soluble Potash Resources in Zhejiang Province

随着生态、高效农业的发展 ,浙江省的化肥需求发生了变化 ,钾肥、磷肥和复合肥需求增加 ,但生产钾肥、复合肥等的可溶性钾矿资源奇缺 ;而难溶性钾矿资源丰富。本文在分析难溶性钾矿资源优势的基础上 ,建议加大综合利用明矾石、伊利石制钾肥的力度 ;利用东阳大爽钾长石矿资源生产钾肥 ;对利用富钾砂页岩、凝灰岩制钾肥开展研究 。

With the development of ecological agriculture and high efficient agriculture, the needs for chemical fertilizers have changed. There is a growing need for potassic, phosphate and compound fertilizers. However, there is a very serious shortage of soluble potash mineral resources, a necessity for producing potassic and compound fertilizers. On the other hand, there is abundance in insoluble potash mineral resources. This paper discusses the advantages of the insoluble potash mineral resources and suggests the comprehensive exploitation of alunite and illite and the utilization of the potash spar resources in Dashuang,Dongyang to produce potassic fertilizers. Research on the production of potassic fertilizer using high potash sandy shale and tufa is also recommended so as to satisfy the needs of agriculture for fertilizers.
