我矿菱镁矿浮选厂,自1985年建成投产以来,一直采用先反浮选再正浮选工艺流程。所用药剂有十二胺、松醇油、氧化石蜡皂、水玻璃。随着生产的发展,生产上出现泡沫发粘、跑槽、尾矿难以输送的问题。为此,我们通过试验研究,取消松醇油,解决了上述问题。 1.试验及结果。试样取自粉子山矿区的混合矿石,先破碎至-2毫米,再磨细至65—70％-0.074毫米。试样含SiO_25.5—5.8％,Fe_2O_3
Mine mine magnesite flotation plant, put into operation since 1985, has been using the first anti-flotation re-flotation process. The agents used are dodecylamine, pine spirit, paraffin soap, water glass. With the development of production, the production of sticky foam, running groove, tailings difficult to transport problems. To this end, we through the pilot study, cancel the pine oil, to solve the above problems. 1. Tests and results The samples were taken from the mixed ore in the Powder Hill Mine, crushed to -2 mm and then ground to 65-70% -0.074 mm. Sample containing SiO_25.5-5.8%, Fe_2O_3
