【摘要】：以莫桑比克安夸贝石墨浮选精矿为原矿,根据其性质,采用化学提纯方法,通过对碱的用量、焙烧温度、混酸种类和用量、反应温度及时间等因素进行试验研究,确定适宜的反应条件。研究结果表明:采用氢氟酸法将品位为95.99%的大鳞片石墨提纯至99.98%,采用碱酸法提纯至99.96%。
[Abstract]:Based on the properties of Mozambican anquarbe graphite flotation concentrate, the factors of alkali dosage, calcination temperature, mixed acid type and dosage, reaction temperature and reaction time were studied by means of chemical purification method. The optimum reaction conditions were determined. The results showed that the grade of 95.99% flake graphite was purified to 99.98 by hydrofluoric acid method, and the alkali-acid method was used to purify to 99.96g.
