前言四川省清平磷矿是我国大型磷矿床。该矿由磷块岩和硫磷铝锶矿两种矿石组成。其中硫磷铝锶矿是国内外罕见的一种以磷为主,伴生有硫、铝、锶、稀土等多种有用组分的新型磷矿石。目前建设第二磷矿基地是四川急待解决的问题。清平磷矿是一个较理想的后备磷矿基地。硫磷铝锶矿是磷块岩的直接顶板,因此磷块岩开采时,必须决定硫磷铝锶矿是否能够利用的问题,不解决这个问题,不仅会造成资源的浪费,也影响到磷块岩的开发利用。该矿床在一九五八年就已发现,二十多年来由于上述利用问题一直未能解决,使其成为呆矿。
Preface Qingping phosphate rock in Sichuan Province is China’s large phosphate deposit. The mine is composed of two types of ores, phosphorite and parathionite. Among them, strontium aluminophosphate is a rare phosphorus-based phosphate rock at home and abroad, accompanied by sulfur, aluminum, strontium, rare earth and other useful components of new phosphate rock. At present, the construction of the second phosphate base is an urgent problem to be solved in Sichuan. Qingping phosphate rock is a more ideal reserve phosphate base. Phosphorous strontium aluminophosphate is the direct roof of phosphorous rock, phosphorous rock mining, we must decide whether the strometoal can use the problem, do not solve this problem, not only will result in the waste of resources, but also affect the phosphorus Rock development and utilization. The deposit, which was discovered in 1958, has been found to have become a domiciliary mine for more than two decades because of the above problems of utilization.
