Calcite Processing by Flotation for Beneficiation

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.

Calcite mining and processing plant

Copper extraction was a many step process in an attempt to be as efficient as possible. Chalcocite and covellite were sent directly to the smelting plant in Tacoma. Malachite, azurite, and other forms of copper within the limestone needed separation in the 14-story mill building before shipment.The mill was mainly built between 1909 and 1923.

The optimization of the operating parameters of a stirred media mill in the dry grinding of calcite was investigated. A three-level Box-Behnken design was used for the purpose of examining the impact of four independent factors, the stirrer speed (SS), grinding time (GT), media filling ratio (MFR), and solid mass fraction (SMF), on the product particle size (d50).
