To make its calcium carbonate product for the concrete industry, a large mine in Brazil uses reverse froth flotation to purify the calcite ore feed material containing silicate-magnesium mineral impurities, such as phlogopite. Since magnesium oxide negatively reacts with water in concrete applications, the mine requires an MgO grade of lower than 5.5% in its concentrate.
The flotation tailing (froth product) was collected for 3 min. In the study, the effect of different collectors, flotation pH values, and mixed collector rates were investigated.
Calcite is activated and floated into the froth concentrate while the sericite, quartz, and other silicates are depressed and rejected into the flotation tailing. The froth from the last 2 or 3 cells of the "Sub-A" calcite flotation circuit may be recycled, if desired to maintain grade and provide a final refuse low in calcite.
