世界钾盐生产主要以可溶性钾盐资源为主,预计现有探明储量可供世界开采240年以上。2011年,全球钾肥产能4460万吨/年(以K2O计),比上年增长6%,产量3700万吨(以K2O计),比上年增长9.6%,有近600万~650万吨K2O剩余,预计到2015年全球钾肥产能将增至5960万吨/年。2012年,我国资源型钾肥总产能540万吨/年(以K2O计),比上年增长12.5%,总产量377万吨,表观消费量769万吨。预
The world’s potash production is dominated by soluble potash resources and the existing proven reserves are expected to be available to the world for mining for more than 240 years. In 2011, the global potash production capacity was 44.6 million tons / year (calculated as K2O), an increase of 6% over the previous year and the output was 37 million tons (calculated as K2O), an increase of 9.6% over the previous year with nearly 6 million to 6.5 million tons of K2O Surplus, it is estimated that by 2015 the global potash production capacity will increase to 59.6 million tons / year. In 2012, China’s resource-based potash production capacity was 5.4 million tons / year (calculated as K2O), up 12.5% over the previous year with a total output of 3.77 million tons and an apparent consumption of 7.69 million tons.
