This paper introduces the research on the beneficiation of a low-grade barite ore taken from Myanmar.Through the analysis of the ore properties and research on the flotation experiment, the optimum flotation conditions are determinedwhile the ore sample assays 64.32% BaSO4.Under the flotation conditions of the grinding fineness-200 meshes 80%, sodium oleate 800g / t and sodium silicate 500 g / t, “two-time roughing,one closed cleaningand open in the second cleaning operations” is applied, and two marketable barite concentrates can be obtained. The concentrate 1 and 2 contain 96.32% and 91.26%BaSO4 at the recoveries of 91.94% and 5.25%, respectively.

Taking molybdenum tailings as the research object, the methods of recovering phlogopite on the base of comprehensive utilizations of other valuable minerals has been discussed. The best flotation condition includes that pulp density is 25%, the value of pH is 8.4, and the spindle speed of the batch flotation cell is 1850 r/min, sodium silicate is used as the silicate inhibitor, sodium oleate as collector, alkyl amine as the foaming agent. After cleaning and scavenging, the yield of the recovery and grade of concentrated phlogopite could be reached above 40% and 9.5%, and the yield of recovery and grade of scavenged phlogopite could be reached above 20% and 7.0%. The experimental research may provide the theoretical and experimental basis for phlogopite flotation from molybdenum tailings.

Beneficiation of a low-grade barite ore assaying 64.32% BaSO4 was conducted by flotation using sodium oleate and sodium silicate. The effect of grinding fineness, type and dosage of flotation reagent in roughing were investigated. Based on the optimum flotation conditions, a close circuit flowsheet was established. Finally, two barite concentrates assaying 96.32% and 91.26% BaSO4 can be obtained at the recovery of 91.94% and 5.25%, respectively, by applying two-time roughing and two-time cleaning operations.

In this study, the single mineral flotation experiments of magnesite and its associated minerals including dolomite, serpentine, talc and quartz were conducted, and the influences of the dosage of collectors such as sodium oleate and lauryl amine, pH value and the influences of regulars such as sodium hexametaphosphate and sodium silicate on those minerals were researched. According to the results, a process to reduce the content of gangue minerals was proposed, which at first use lauryl amine as a collector to remove most talc and quartz and part of the dolomite and serpentine, and then use sodium oleate as a collector to separate magnesite from dolomite and serpentine. This is a theoretical reference for the beneficiation of magnesite.

In alkaline condition, experiments were taken to investigate the influence of different regulators on the flotation behaviors of brucite and serpentine when sodium oleate was the collector. The regulators used in experiments included sodium silicate, tannin and calcium lignosulphonate. The results showed that sodium silicate had a great effect on the flotation. When the regulator was the sodium silicate, serpentine recovery rate was less than 10% and brucite recovery was about 90% in the pH of 10. After analysis, brucite and serpentine may be separated effectively by sodium silicate. At last, the function mechanism of sodium silicate was probed. The electrostatic adhesion between serpentine and sodium silicate accured, and the surface of serpentine was negative so that it was difficult to be collected by sodium oleate; Instead, the impact of sodium silicate on brucite was weak, and the surface of brucite was still positive so that it could be collected easily.
