Li Zhiwei et al. conducted a wet extraction of vanadium pentoxide from a vanadium ore in Henan Province, using a strong acid leaching-solution extraction-sulfuric acid stripping-ammonia vanadium-calcination vanadium process, using 1% oxidizing agent sodium chlorate, grinding The fineness of the ore is 65%-0.074mm, the leaching temperature is 90°C, the liquid-solid ratio is 1:1, the sulfuric acid dosage is 30%, and the leaching time is 10h. The vanadium leaching rate reaches 92.50%; the leachate uses P-204, P- 507, TBP solution was extracted and sulfonated kerosene, sulfuric acid solution was back extracted, via oxidation, ammonia precipitation, pyrolysis, comprehensive recovery to a purity of 98.56%, vanadium is greater than 85%. Gao Yude et al. conducted a mineral processing test on a scheelite in Hunan. Adopting the preferred float sulphur-white tungsten at room temperature rough selection-tungsten concentrate concentrate heating process and sodium carbonate-water glass-F9 combination pharmacy system, the tungsten content is 0.39%, and the distribution rate of tungsten in scheelite is 85%. The raw ore of the right and left has obtained the mineral processing technical index of 67.35% of tungsten concentrate grade and recovery rate of 80.09%. Zhang Aiping conducted a flotation test on a high-sulfur scheelite ore. The results show that under the conditions of grinding fineness 70%～75%-0.074mm, pre-flotation desulfurization and flotation of white tungsten at room temperature, the ideal index of 62.87% of scheelite concentrate and recovery rate of 84.33%. Liu Meihua conducted a tailing test study on the characteristics of a low-grade tin ore using three different re-election methods: spiral chute, jigging and shaker. The results show that the shaker tail throwing is an effective method for pre-selection of the mine. The grade of tin coarse concentrate is increased from 0.37% to 3%, the recovery rate is 72.37%, the tailings yield of thrown is 60%, and the tin is in the tailings. The loss in the case was only 15.89%, which provided favorable conditions for subsequent tin recycling operations. Sun Yang Once a test Beneficiation of antimony ore Shaanxi to be found using Southern dextrin can be effectively suppressed pyrite ores using diethyldithiocarbamate, and butyl xanthate butylammonium aerofloat captive by mixing The collecting agent can make the pyrite and the strontium minerals be well separated. By re-grinding the coarse concentrate, the strontium minerals in the coarse concentrate can be separated as much as possible, thereby improving the sorting technical index. Cai Zhenlei et al. conducted a rare earth ore dressing test on the tailings obtained by magnetic roasting and weak magnetic separation of the strong magnetic separation coarse concentrate in Baotou Steel Concentrator. The results showed that the mixed flotation concentrate was obtained by pre-decarburization and mixed flotation, and after 1 rough selection, 3 selections and 1 sweeping, the final REO grade was 64.4 1%, and the recovery rate was 18.13%. Rare earth concentrate products. Yu Xiulan et al. studied the reaction principle and process of adding carbon and chlorination to extract rare earth from the tailings of Baotou Steel Concentrator after desulfurization with A1cl 3 or MgO, and investigated the time of carbon thermal chlorination and the extraction rate of rare earth from defluorination agent. influences. Results Yuan Ming, carbon chlorination at 700 ° C for 2 h. When AlCl 3 is used as the defluorination agent, the rare earth extraction rate can reach 77%; when Mg0 is used as the defluorination agent, the rare earth extraction rate can reach 84%. In order to effectively reduce the impact of slime flotation of rutile, Gregory Kun on a Refractory Rutile Ore Flotation Test Anti conducted. The results show that the inhibition of rutile with aluminum sulfate and the reverse flotation with sodium oleate can discard a certain amount of foam products, wherein the rutile grade is 0.39%, the -0.010mm fraction removal rate is 74.79%, which is the positive flotation of rutile. The favorable conditions were created; the deliming 20 pairs of rutile was subjected to positive flotation, and after 1 rough selection, a rutile coarse concentrate with a grade of 20.30% and a recovery rate of 83.88% was obtained.
