Abstract:
The Mining sector is one that significantly contributes to the development of society by providing raw materials for a wide range of industries. Considering the decreasing iron grades over the lifespan of the mine, as well as the demand to work with ultrafine materials, studying new routes to benefit these materials becomes necessary. The purpose of this study is to conduct an evaluation of the technical feasibility of an alternative route for the Sinter feed product. Pilot tests of magnetic separation were performed, varying parameters to achieve quality and mass recovery. The test results presented two possible routes according to the client's needs. In the first route, an overall mass recovery of 50.73% was achieved, with an iron content in the product of 61.73%, and a reject with 40% Fe. It's worth noting that in this route, a Fe content of 62.45% was achieved in the rougher stage. The second route obtained an overall mass recovery of 40.80%, with product quality of 61.38%, and reject containing 32.89% Fe. The study was conducted for a specific case in the context of the mining industry in Minas Gerais. It becomes feasible to utilize the mentioned routes for this material, provided that all aspects are evaluated, whether partially or fully employing this material in one of the routes. As future work, further sampling campaigns and new magnetic separation tests are necessary.
