Adjustment of the mineral processing reagents you know how much
Adjust the agent can be divided into five categories:
(1) the pH adjustment. Use it to adjust the ph value of slurry, in order to control the mineral surface properties, pulp chemical composition as well as other conditions of different types of drugs, thus improving flotation effect. Also in the process of cyanide to adjust slurry pH value. The commonly used such as lime, sodium carbonate, sodium hydroxide and sulfuric acid. When picking the gold, the most commonly used regulator is lime and sulphuric acid.
(2) activator. Can enhance the effect of mineral collector with ability to make difficult floating minerals by activation and float. Using sodium sulfide lead copper oxide ore containing gold activation, and then use xanthate flotation collector, etc.
. (3) inhibitors improve mineral hydrophilicity and prevent mineral collector with role, make its flotability is restrained. As in the selective flotation process using lime inhibiting pyrite, sphalerite suppressed with zinc sulfate and cyanide, inhibition of silicate gangue minerals, such as water glass, using starch, mimosa extract (tannin), and other organic compounds as inhibitors to achieve the purpose of many metal separation flotation.
(4) flocculant. Make fine mineral particles assembled into larger particles, in order to speed up its settling velocity in the water; The use of selective flocculation for flocculation desliming and flocculation flotation. Common flocculants such as polyacrylamide and starch. (5) the dispersant. Stop fine ore grain gathered in a single state, its role and flocculating agent on the contrary, the commonly used sodium silicate, phosphate, etc.
The variety and dosage of flotation reagent with ore properties and flotation conditions and process characteristics of each different, the available test units to provide a prescription) (or the agent system, in the process of production practice can also be in accordance with the above conditions change and change.
