ric acid and potassium dichromate, respectively. Therefore, for the application to ores, our final choice of optimal flotation requirements focused on Petronate L (1000 g/t) used at pH 6,5 for the flotation of barite, the Flotbel R171A (100 g/t, pH 9) for the flotation of fluorite and potassium di-chromate (500 g/t) as a depressing agent of barite.

Potassium dichromate Wikipedia

Potassium dichromate, K 2 Cr 2 O 7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is acutely and chronically harmful to health. It is a crystalline ionic solid with a very bright, red-orange color. The salt is popular in the laboratory because it is not

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. The final flotation treatment has led to the obtention of a barite concentrate with a 93,4% BaSO4
