从云南省科技厅获悉,该省研发出国内最大柱浮选选矿技术并成功应用。该技术突破传统磷矿开采方式,提高了磷矿资源的开发利用水平,对支持磷化工支柱产业的可持续发展具有深远意义。云南省的磷矿探明储量居全国首位,但是长期以来的“取富弃贫”的开采方式导致云南省的磷矿资源浪费较大,92%的中、低品位磷矿没有得到综合利用。为解决这一影响可持续发展的关键问题,云南省科技厅立项支持云南云天化集团进行了“中、低品位 It was learned from the Science and Technology Department of Yunnan Province that the province has developed the largest pillar flotation beneficiation technology and successfully applied it. The technology to break through the traditional method of phosphate rock mining and improve the level of exploitation and utilization of phosphate rock resources, to support the sustainable development of the pillar industry of phosphorus chemical has far-reaching significance. Yunnan Province has the largest proven reserves of phosphate rock in the country, but its long history of ”abandoning the rich and abandoning the poor“ has led to a waste of phosphate rock resources in Yunnan Province. 92% of medium- and low-grade phosphate rock have not been consolidated use. In order to solve this key issue of sustainable development, Yunnan Science and Technology Agency project to support Yunnan Yuntianhua Group conducted a ”medium and low grade
