    Copper Concentrate regrind at Sossego Plant using Vertical

    In general, the specific energy consumption at this stage is higher than during the primary grinding stages. In addition, a tendency of finer grinding has been observed in the new projects of metallic minerals, due to the finer mineral liberation, which leads to increasing capital and operational costs. At Vale’s new copper projects in Brazil, regrind sizes with a P80 of approximately 40 to 20 m have
