When the tailings pulp concentration is greater than 56%, the curing strength can exceed 0.5 MPa at 3 d. Therefore, feldspar concentrate meeting ceramic standards with whiteness of 58.63 is obtained, and the remaining low value components are filled back to the ground, making it a secondary resource rather than a waste with environmental threats.
Granite tailings are rich in quartz and feldspar with high recycling value. However, quartz-feldspar separation usually adds sulfuric acid and hydrofluoric acid, which inevitably leads to equipment corrosion and environmental pollution. This study introduced an alkaline-based flotation method to treat granite tailings.
