Adjusting agent can be divided into five categories:
(1) pH value adjusting agent. It is used to adjust the pulp pH value, used to control the characteristics and conditions of mineral surface pulp chemical composition and various other agents, so as to improve the flotation effect. In the cyaniding process also to adjust the pH value of the pulp. Commonly used with lime, sodium carbonate, sodium hydroxide and sulfuric acid etc.. In gold, regulator is the most commonly used lime and sulphuric acid.
(2) the activator. Can enhance the mineral flotation agent with ability, make difficult floated mineral are active and float. Lead and copper oxide ores using sodium sulfide activated gold, then with xanthate as collector flotation.
(3) inhibitors. Improve the hydrophilicity and prevent mineral mineral collectors with catching effect, make its floatabilityinhibited. Lime as used in priority flotation process inhibition of pyrite, sphalerite by inhibition of zinc sulfate and cyanideinhibition of silicate gangue minerals, water glass, the use of starch, tannic (Dan Ning) and other organic matter as inhibitors ofreach the purpose of multi metal flotation separation.
(4) flocculant. The fine mineral particles agglomerate into large particles, in order to accelerate its settling velocity in water;flocculation desliming and of a flocculating flotation by selective flocculation. Commonly used flocculants polyacrylamide and starch. (5) dispersing agent. Prevent the fine mineral particle aggregation in a single state, its role and flocculant on the contrary, there is a commonly used water glass, the phosphate.
The type and the amount of flotation agent with the ore properties and flotation conditions and process characteristics and different, available test units to provide prescription (or reagent system), in the practice of production can also change according to the various conditions and to change
