The origin and composition of secondary barite materials as well as their behaviour during froth flotation studies is discussed. Five possible barite sources were investigated: Mining wastes mill tailings Black Ash process residues neutralization slurries from barite bleaches and drilling sludge.
Firstly was studied the barite behaviour during flotation in a classic cell using samples of pure barite and associated minerals. The influence of different parameters nature of collectors
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
of flotation were applied to barite and fluorite-barite ores. Definitive choice of optimal flotation requirements focused on Petronate L 1000 g/t ; pH 6.5 for barite flotation and on Flotbel R171A 100 g/t ; pH 9 for fluorite combined with potassium dichromate as depressing agent for quartz and barite.
Barite Flotation El Cuervo Butte Michael J. Harris Metallurgist New Mexico Bureau of Mines and Mineral Resources June 1988 Abstract Barite Bas04 1 is an essential industrial mineral used for both its chemical and
and on a barite ore. The best performance was reached with the use of Petronate L 1000 g/t; pH 6.5 for barite flotation leading to the obtention of a barite concentrate with a 95.1% BaSO4 grade answering the oil industry
Barite can be efficiently floated with ArrMaz’s custom flotation reagents in an alkaline and neutral pH range and is easily depressed in an acidic circuit. Our CustoFloat 5919 and 5920 collectors in particular have demonstrated high selectivity and good recovery and have been successfully used by the industry.
Flotation tests on artificially mixed minerals of fluorite 0.5 g and barite 1.5 g were conducted three times to measure the separation efficiency of SHMP and the average results are summarized in Table 2. The concentrate
