    and the traditional dry grinding method was used as a reference. The effect of wet grinding on the activation of IOTs was evaluated through ion leaching from an alkaline solution and the reactivity index. Additionally, a detailed comparison between Drygrinding Iron Ore Tail ings (DIOTs) and Wetgrinding Iron Ore Tailings (WIOTs) was made.

  • What Are Tailings?

    Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never efficient, nor is it possible to reclaim all reusable and expended processing reagents and ...

    Dry processing is associated with the quality of the iron ore from the mine face. In Carajás, as the iron content is already high (above 65% iron), the material is only crushed and screened to be classified by size (granulometry). In some mines of Minas Gerais, the average content is 40% iron in rocks known as itabirite. To increase its grade, the ore is concentrated through .
