青海察尔汗盐湖,面积5856平方公里,各种盐类储量约600亿吨,以钾盐为主,还伴生钠、镁、硼、锂、溴、碘、铷、铯等元素,已探明氧化钾工业储量2.45亿吨,占全国总储量90％以上。 察尔汗盐湖的开发。自五十年代就得到国家的高度重视,三十年来在科研、生产、建设等方面做了大量工作,具备了大规模综合开发的条件。1958年兴建的察尔汗钾肥厂(现青钾第一选矿厂)已生产钾肥70万吨,产值2亿多元,上缴利润一亿多元。上千名盐湖拓荒者、建设者在条件极为艰苦的环境中艰苦创业,在采卤、盐田、加工、防腐等
Qinghai Chaerhan Salt Lake, an area of 5,856 square kilometers, all kinds of salt reserves of about 600 tons, mainly potassium, but also associated with sodium, magnesium, boron, lithium, bromine, iodine, rubidium, cesium and other elements, has proven 245 million tons of industrial reserves of potassium oxide, accounting for more than 90% of the total reserves. Chalhan Salt Lake development. Since the 1950s, China has attached great importance to the state. In the past 30 years, China has done a great deal of work in scientific research, production and construction, and has possessed the conditions for large-scale comprehensive development. The Chaerhan Potash Fertilizer Plant (now Qingtu No. 1 Concentrator) built in 1958 has produced 700,000 tons of potash fertilizer with a production value of more than 200 million yuan and a profit of more than 100 million yuan. Thousands of Salt Lake pioneers, builders hard conditions in the arduous pioneering environment, mining halogen, salt fields, processing, preservation, etc.
