湖南临湘桃林刘家坪铅锌萤石矿萤石浮选由于原矿性质较复杂,主要是原矿含重晶石较高7.4％～12％。浮选的萤矿精矿品位难以达到优级与酸级要求。为解决此问题,提高萤石精矿产品质量,我们采取“在中性或弱碱性矿浆中粗选,精选酸性分离、排除部分中矿”的选矿工艺流程,获得了萤石精矿品位为96.60％,萤石回收率为58％的较好生产
Hunan Linxiang Taolin Liujiaping lead-zinc fluorite fluorite flotation Because of the nature of the more complex ore, mainly ore containing barite higher 7.4% ~ 12%. Flotation of the grade of the ore concentrate is difficult to achieve superior and acid grade requirements. In order to solve this problem and improve the quality of fluorite concentrate, we adopted the beneficiation process of “rough selection in neutral or weakly alkaline slurry, selective acid separation and exclusion of part of middle ore”, and obtained the fluorite concentrate grade 96.60%, fluorite recovery rate of 58% of the better production
