摘要：中国钾资源匮乏,钾肥供给事关农业粮食安全。青海已建成全国重要且最大的氯化钾生产基地,如何可持续开发利用钾资源,是保障国家钾肥供给安全的关键。列举了青海盐湖钾资源状况,介绍了近年来青海氯化物型盐湖钾资源勘探与开采的研究进展,总结了冷分解-正浮选、冷结晶-正浮选和反浮选-冷结晶三种主流工艺的技术进展,并对青海盐湖钾资源未来保障供给的关键技术发展趋势进行了展望,包括深部钾资源勘探、现有钾资源高效利用、中西部硫酸镁亚型盐湖钾资源有效开发、贫杂钾矿资源高效开采与技术等。
Potassium resources are scarce in China and the supply of potash fertilizer concerns the security of agricultural food.An important and largest production base of potassium chloride has been built in Qinghai,China.How to develop and utilize potassium resources sustainably is crucial to ensure the security of the national potash fertilizer supply.The salt lake potassium resources status in Qinghai was listed,the chloride type of salt lake potassium resources research advances of Qinghai in exploration and exploitation in recent years were introduced,and technological improvement of three kinds of the main flowsheet were summarized,including cold decomposition‐direct flotation,cold crystallization‐direct flotation,and re‐verse flotation‐cold crystallization.Moreover,the key technology development tendency of salt lake potassium resources fu‐ture guaranteeing supply of Qinghai was prospected,which included the deep exploration of potassium resources,efficient utilization of potassium resources,and effective exploitation of middle‐western magnesium sulfate subtype salt lakes potas‐sium resources and efficient exploitation technology of poor mixed potassium ore resources,etc.
