The Addition Location and Method of Flotation Reagents

Mar 25, 20193 The flotation reagents whose dosage requires strict control, such us sodium sulfide. When the local concentration is too large, the selection effect of the flotation reagents will be weakened. Therefore, it is necessary to add in batches to ensure that the concentration of the flotation reagents is maintained to a certain level.

How to Prepare Flotation Reagent?

Mar 25, 2019In order to improve the water solubility of the mixed flotation reagent, when preparing the flotation agent, we can add about 10% of sodium carbonate to saponify the tall oil and heat the mixture with hot water to prepare a hot soap liquid. Another example is the water solubility of oleic acid is very poor, but after adding sodium carbonate to

Dec 20, 2018The specific process of flotation is to add various flotation reagents to a certain concentration of slurry, and a large number of diffuse bubbles are generated by stirring and aeration in the flotation machine. At this time, the suspended ore collides with the bubbles, and some of The floatable ore particles adhere to the bubbles, and float up

Regarding the flotation machine, what aspects do we need

Answer: 1. The composition of ore is complex, that the distribution of precious metals such as gold, silver and so on is dispersed, which has a great influence on the comprehensive recovery of ore. So you should have a mineral test before choosing flotation. 2. The result of grinding would affe

Flotation techniques most frequently used: zinc sulfate or Sheather sugar use solutions which have higher specific gravity than the organisms to be floated so that the organisms rise to the top and the debris sinks to the bottom. The main advantage of this technique is to produce a cleaner material than the sedimentation technique

Nov 01, 2011In flotation cells, we add air, create bubbles of a certain size and speed that provide the surface area to do the flotation. The more bubbles and the smaller the bubble, the more surface area we have to do the work. This surface area we create is known as the surface bubble flux Sb and controls the kinetics of flotation.
