摘要
China is a large agricultural country, and there exists a big gap in the utilization of potash fertilizers; nevertheless, China is also a country with numerous salt lakes. Potash resources in salt lakes constitute hopeful conditions for solving China’s shortage of potash fertilizers. This paper presents the study and analysis of the resources situation and processing procedures for Qarhan and Lop Nur. The experience gained in their successful exploitation can serve as guidance for the exploitation of other salt lakes of the same subtype. A discussion on the possible way of exploiting salt lakes of the carbonate subtype is also made, which demonstrates that potash products from salt lakes of carbonate subtype can be obtained in situ through technological innovation. It is indicated that different technological processes should be employed in the exploitation of different subtypes of salt lakes.
