浮选浮选实践将来,随着较贫矿石的扩大开发,复杂矿石的分选不免更加困难。回路设计的革新与改进必须与浮选槽的设计和新的更优药剂的研制相配合进行。多给矿回路的设计研究可望成为此类矿石回路选择的一个主要部分。多给矿回路不同于常规回路,它有二股或更多的给矿给入(图2)。迄今尚未公开的报告指出,此法在回收率和品位(通过自背负)方面都有提高,而且节约了浮选药
Flotation flotation practice In the future, with the development of poorer ore, it is even more difficult to sort the complicated ore. Innovations and improvements in circuit design must be made in conjunction with the design of flotation cells and the development of new, better agents. Design of multi-feeder circuits is expected to be a major part of the selection of such ore circuits. The multi-feed mine circuit differs from the conventional one in that it has two or more feeds to the mine (Figure 2). As yet unpublished reports indicate that this method has been improved in terms of recovery rate and grade (by self-sustaining), but also saves flotation drugs
