iron ore flotation process at brazil

Abstract. The Brucutu iron ore mine (Minas Gerais, Brazil) is Vale‘s largest iron producing operation achieving around 21 million tons per annum. Evaluation of flotation performance is of high importance as even small gains can lead to large monetary benefits. Cell-by-cell samples of the froth products, selected feed and pulp-products were analyzed for flow rate, particle size distribution and chemical composition

    Regarding Brazilian iron ore processing plants, the typical flotation feed consists of particles in the size range between 10 m and 300 m and the desliming process is carried out by hydrocyclones ; thus, the Fe content in the Brazilian slimes is high in comparison to the slimes produced by the selective flocculation process

Best results were obtained with the amide-amines N-(3-(dimethylamino) propyl)-dodecanamide) and a mixture with N-(2-(2-aminoethyl-amino) ethyl)-dodecanamide) having open

    The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 m up to 150 m. The presence of the slimes (Ps 10 m) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents consumption, the froth stability
