Research on the Flotation Experiment of a Low-Grade Barite Ore in Myanmar

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.
