我国一直是钙镁磷肥最大的生产国和消费国,近几年来,受高浓度磷复肥的冲击,钙镁磷肥的产销在一个较低的水平上徘徊。然而,从我国的实际情况出发,应尽快恢复钙镁磷肥产业,重视生产、推广使用颗粒钙镁磷肥。我国磷矿以低品位矿为主,通过选矿生产高浓度磷肥将造成较大的磷矿资源浪 China has been the largest producer of calcium magnesium phosphate fertilizer and consumer countries, in recent years, the impact of high concentrations of phosphate compound fertilizer, calcium magnesium phosphate fertilizer production and sales at a lower level hovering. However, proceeding from the actual situation in our country, we should resume the industry of calcium magnesium phosphate fertilizer as soon as possible, pay attention to production and promote the use of granular calcium magnesium phosphate fertilizer. China’s phosphate rock is dominated by low-grade ore, producing high concentration of phosphate fertilizer through beneficiation will cause greater phosphate rock resources
