Mine needs to undertake below basic requirement with the mixture floatation of floatation machine, normally requirement PH value is between 7.5-9.5, the depressor such as lime and prussiate or vitriolic zinc is added in the mixture floatation circuit that wears machine and floatation aircraft equipment together. Reach the vulcanization mine of iron to restrain zinc occasionally, need works in concentration paragraph fill add a few sulphurous acid natrium or 2 oxidation sulfur, but these drug want careful with, because they also restrain the floatation effect of galena.
Of the mixture floatation that chooses machine technology with Yu Fu it is very important to catch the option that receives a dose and dosage to work to mixing floatation not only, and also have very crucial effect to follow-up mineral and separate operation. In floatation process, we use Huang Yao generally to regard as catch receive a dose, the short cable length such as second radical yellow medicine is caught in receiving an agent to be chosen in the float of galena and chalcopyrite, have very tall alternative, and can make copper - lead achieves effective depart, but of mixture concentrate reclaim rate is not high, especially of galena reclaim rate. The major galena that did not get reclaiming can be in follow-up zincic floatation work rise, pollute zincic concentrate thereby, cause economically loss. Normally, dosage is lesser, interpose is mixed at 0.02kg/t between 0.06kg/t, if dosage crosses congress to make copper - plumbic depart is difficult, need to join many depressor, this may make already of rise mineral be restrained, pollute the concentrate of lead and copper.
Expert of machinery of Henan SBM mine studies equipment of production floatation aircraft is old, have rich floatation aircraft equipment to make experience, my company technologist will raise mine product ceaselessly to pledge the quantity increases equipment to be led to mineral reclaiming, realize floatation machine hard technological process maximize.
