Temperature control is very important, because when the pulp temperature is high, the interaction of flotation reagents effect is stronger, faster, and the interaction is weak at low temperature and slow, flotation indexes which can reduce the mineral processing reagents; In order to promote the sulphide effect of sodium sulfide, it is also necessary to warm the pulp in order to promote the sulfide effect of sodium sulfide. When the mineral is floor-free, the demand for temperature is higher. Because the winter and summer temperature difference is too big, pulp temperature difference is very big also, in order to no seasonal fluctuations, the index of flotation technology for pulp temperature also needs special attention. Therefore, the influence of pulp temperature on flotation is not negligible. But because of the large amount of pulp in the mine, it is very uneconomical to heat up the pulp in order to adjust the temperature simply to adjust the temperature. So, the flotation process of the mineral is normally carried out at room temperature. The pulp temperature does not affect all minerals, such as yellow drugs; The yellow drug is easier to dissolve in water when making flotation, so the temperature does not affect it much and does not need to be warmed up.
The best flotation drugs have to meet three requirements first.
A, first we need to see a flotation reagents mixing effect, to ensure that because the mineral processing reagents for pulp has good mixing effect, can make the particles from precipitation and went into a state of suspension, and can be evenly distributed in the slot. Ensure that the ore is fully exposed and colliding in the tank. It also encourages the dissolution and dispersion of some insoluble agents, which are beneficial to the full effect of the agents and the granules.
Secondly, high quality flotation drugs are good for inflating. The mineral must be made to be able to absorb (or press) enough air into the pulp to produce large quantities of suitable bubbles. As far as possible and make the bubbles scattered throughout the tank, air dispersion as thin as possible, the bubble distribution more uniform, the ore particles and bubbles the opportunity to contact more and more, the better the performance of the process that the mineral processing reagents, the higher the performance of the flotation, degree of mineral processing reagents, inflated by your said.
Finally, the circulation of flotation agents. Good beneficiation reagents have adjust the volume of pulp, pulp cycle, your role, can increase the chance of ore grain contact with air bubble, can maintain smooth bubble area and has a certain thickness, mineral can retention purpose, and can make the mixed gangue loss, produce "secondary enrichment" can work continuously and easy to adjust. In the process of flotation, the thickness of the entire foam layer and the discharge of the slurry need to be adjusted. In the actual production application, the discharge of ore from the ore to the surface of the mine and the tailings is the continuous process, which should be adjusted easily.
