Upgrading Beneficiation for the High Grade of Quartzite Ore
In other words, as a result of reverse flotation with the addition of 50 g/ton of Armac C to quartzite ore milling products of less than 100 mesh, which were processed by desliming and wet magnetic separation, high-grade refined silicate concentrate of 99.50% (or more) SiO 2 was recovered.
