Carbonaceous Ores The increase in demand for phosphate is accompanied by a rapid depletion of high-grade ores.Application of the grade-recovery curve in the batch,,Aug 01, 2013· Therefore, the symbols of the ores investigated in this work and given in Table 1 include region (L for Lubin, R for Rudna), ore geological location (G1, G2, etc.), and ore type (P for sandstone, D for dolomite, and L for shale). The ores were crushed in different size reduction devices to obtain particles smaller than 1 mm in size.A Review of Flotation Separation of Mg Carbonates,,It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg carbonates have high levels of adverse effects on separation efficiency.
