Barite recovery from secondary sources by froth flotation

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

Research on the Flotation Experiment of a Low-Grade Barite

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.

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

Maximize Barite Recovery and Grade ArrMaz

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 studies of fluorite and barite with sodium petroleum

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
