Scheelite flotation of phosphate minerals scheelite cause excessive levels of phosphorus, the usual approach is to pickling or shaking reselection separation, but rare earth minerals memory phosphorus ore, monazite caused excessive phosphorus can not do anything. To this end, Huang Baoguang in the flotation of water glass to suppress phosphorus-containing rare earth minerals and apatite, achieved better technical indicators, solved the problem of acid leaching and shaker re-separation separation can not be sorted, and dealt with a backlog of The scheelite concentrate with high phosphorus content has created significant economic benefits for the enterprise. The water glass modulus is the main parameter of the flotation scheelite. A skarn type scheelite uses low modulus water glass as an inhibitor of gangue minerals. The modulus determined by the test is 2.2. At this time, the amount of water glass selected by scheelite is 5000 g/t. Through a small closed-circuit test, obtained scheelite concentrate containing WO 3 69.84%, WO 3 recovery was 70.76% of the index. According to the nature of scheelite ore, Zhang Zhonghan et al. used a single grinding and single flotation process to coarsely select scheelite with modified Na 2 SiO 3 and modified fatty acid in Na 2 CO 3 alkaline medium, using water glass + YN White tungsten heating selection. Both small and industrial tests have obtained good indicators. In the industrial test containing 1.45% of WO 3 in the ore, a white tungsten concentrate with a grade of 68.19% and a recovery rate of 82.16% was obtained. Gao Germany start from the mechanism of action of fine mud flotation of wolframite fine mud flotation separation of research and fluorite, calcite, quartz and other minerals wolframite right, we made a major breakthrough. In the pulp with a pH of 6.5-7.0, lead nitrate is used as the activator, water glass, aluminum sulfate and the like are combined inhibitors, and the combined collectors such as benzoic acid and tal soap are used as the donor grade WO. 3 1.62%, when the calcium mineral content is more than 70%, and the -40μm particle size accounts for about 90%, the flotation process with WO 3 66.04% and recovery rate of 90.36% can be obtained by one rough selection, three selection and three sweeping processes. Concentrates, technical indicators have reached advanced levels, basically solved the technical problems of calcium-rich mineral black tungsten ore fine mud recovery. Zhou Xiaotong and others used the effective activator ZP of modified water glass and tungsten minerals, and the mixed collector GY to formulate a new process of flotation of black and white tungsten by GY method to treat complex tungsten ore containing 0.599% WO 3 . The small-scale test obtained the excellent selection index, and obtained the scheelite concentrate with the WO 3 grade of 73.26% and the recovery rate of 73.20%, the WO 3 grade of 66.25%, the recovery rate of 13.55%, and the total recovery of tungsten of 86.75%. Concentrate. The process mineralogy characteristics Shizhuyuan Tungsten, Molybdenum fluorite multi-metal ores, research and development of new technology tungsten floating GY law. Selective inhibition of fluorite and other gangue minerals with modified water glass, activation of tungsten minerals with lead salts, mixing of flocculated wolframite and scheelite with a new type of chelating collector (code: GY), for mixing coarse concentrates The heating is selected to obtain a white tungsten concentrate, and the selected tailings are floated with a GY collector to obtain a black tungsten concentrate. Industrial test results show, containing WO 3 0.47% ore, tungsten concentrate grade WO 3 can reach 70.07%, 81.62% tungsten, the total recovery rate. Compared with the 733 oxidized paraffin soap method, the amount of tungsten coarse concentrate is greatly reduced, and the recovery rate is greatly improved. When the white sulphate of Hunan Persimmon Garden polymetallic ore is heated, the mixture of sodium sulphide and water glass can better separate scheelite and gangue minerals than single water glass, which can reduce the amount of water glass and save costs. stably obtain high quality scheelite; warmed featured sodium sulfide in the pulp component is the advantage of a HS, HS-exclusion can be adsorbed on the collector pyrite, pyrrhotite surface and adsorbed It inhibits the surface of the sulfide ore, thus improving the quality of the white tungsten concentrate. Zhu Jianguang believes that the white tungsten thick concentrate plus water glass heating selected Peterlov selected white tungsten method, in addition to adding water glass and adding sodium sulfide to warm the white tungsten coarse concentrate, it should be said to be famous The addition of Petrov Law.
