在钼的浮选中,PH 值是一个重要的影响因素。因为,要提高钼精矿的质量,浮选中要加入一些药剂,如氢化物、石灰、Na~2 S、NaHS 等,所以几乎所有的钼浮选是在碱性矿浆(矿浆 PH 值>7)中进行的。但是,因各矿山钼矿石的类型脉石矿物的组成及所用药剂的不同等原因,各矿山合适的 PH 值也不完全相同。国外矿山的 PH 值,有7、8、9、9.5、10、10.5、11、11.5等,国内矿山有7、8、9.5～10.5、10～11等。
In molybdenum flotation, PH value is an important factor. Because, to improve the quality of molybdenum concentrate, flotation to add some agents, such as hydride, lime, Na ~ 2 S, NaHS, etc., so almost all of the molybdenum flotation is in the alkaline pulp (pulp PH value> 7 ). However, because of the type of molybdenum ore in each mine, the composition of gangue minerals and the use of different chemicals and other reasons, the appropriate mine PH value is not exactly the same. Foreign mining PH value, there are 7,8,9,9.5,10,10.5,11,11.5, etc., the domestic mining 7,8,9.5 ~ 10.5,10 ~ 11 and so on.
