摘要: 通过工艺矿物学研究,查明了青海尖顶山天青石矿的矿物组成,主要元素的赋存形式,矿石的结构、构造及解离度,为选矿试验提供了重要依据。锶主要以硫酸锶独立矿物的形式存在,矿石中的主要脉石矿物为碳酸盐矿物。矿石中的天青石在磨矿细度为100目到200目的范围时,可以获得80%以上的解离度。

关键词: 天青石, 工艺矿物学, 解离度

Abstract: The process mineralogy study was made to identify the mineral composition, occurrence forms, structure and texture, and the liberation degree of Picacho celestite from Qinghai. It is a useful reference for developing celestite ores in this area. The strontium mainly occurs in the forms of strontium sulfate. Carbonate mineral is the main gangue mineral. The liberation degree of celestite is more than 80% when the grinding fineness is between 100 and 200 mesh.

Key words: Celestite, Processing mineralogy, Liberation degree
