Effect of carbonate minerals on quartz flotation behavior …

Therefore, when calcium ion is added as activator of quartz at pH 11.4, calcium exists on the quartz surface mainly in the precipitation of CaCO 3 (s) form; the surface properties of quartz are the same as calcium carbonate. In other words, the flotation characteristics of quartz are similar to calcite.
