SUMMARY:

The use of the Wheel High Intensity Magnetic Separator (WHIMS) stage in phosphate ores has been currently applied in the concentrate after the flotation stage. This application aims to remove minerals containing iron in order to improve the quality of the phosphate concentrate and reduce the impacts on the subsequent chemical process of the production of fertilizers. Stemming from the study using a sample from a mine in Patrocínio, Minas Gerais, this work presents a research proposal to evaluate the application of a WHIMS stage in the phosphate ore beneficiation route prior to flotation, aiming to remove contaminating minerals that impair the recovery of P2O5 during flotation. For this, comparative tests evaluating three situations will be carried out: flotation without a WHIMS stage; flotation with a subsequent WHIMS stage; flotation with a previous WHIMS stage. To carry out the WHIMS, a 3mm matrix will be used and three different magnetic fields will be evaluated – 11,500, 13,500 and 15,500 Gauss. The application of this new route, WHIMS prior to flotation, may increase metallurgical recovery in flotation, therefore increasing the production volume and reducing the costs. Another relevant point is that, since the mass of contaminants will be removed before the flotation stage, the flotation equipment to be utilized in this process are smaller.
