Process flow
Residual barite ore generally gravity separation method for sorting, that is, after washing, crushing, screening with jigging or other gravity separation method to select barite concentrate. For the sedimentary and hydrothermal-type barite ore, the gravity separation process would not satisfy with the requirements of users, in addition to use flotation. Especially when the barite with galena, sphalerite, pyrite and other sulfide ore and fluorite, calcite and other symbiotic associated,only the flotation method can effectively separate.
General Requirements for Barite Flotation Process
1, grinding fineness: barite flotation generally require grinding fineness to 200 mesh,85 to 90%, usually the first paragraph grinding,the classifier overflow into the cyclone, after the cyclone turn into the second stage of grinding, the best grinding fineness need to determine by test.
2, mixing: a strong two stirring tank is appropriate.
3, flotation: the process is generally “one roughand one sweep ”(and some did not sweep) five to six selection, the middlings can be returned or the first selection, second selection followed by the return,the third to five selection together and then discharged tailing Directly. The frequent selection is a feature of barite flotation.
As the regulator of barite flotation mainly sodium silicate, sodium carbonate, and sometimes the ore complex, adding other inhibitors, the collector is mainly oleic acid, oxidized paraffin soap, sodium petroleum sulfonate.The advantages of the above-mentioned collection agent in the actual production is routine, flotation cost is low, easy to operate, etc., but also there are the following aspects of the shortcomings: poor selectivity, difficult to achieve a higher concentrate grade. Concentrate foam amount is huge, make trouble to the concentrate transportation and concentration , and easy to run trough.
