The demolished existing regrind mill will be replaced by a more efficient Outotec Vertimill VTM4500 stirred mill. This will also be in the new building along with new tank cells. Rougher concentrate from all rougher flotation lines will report by gravity to this circuit, where it will be reduced to a P80 of 25 μm.

The use of a gently uprising, aerated fluid greatly reduces the turbulence commonly found in other flotation cells, allowing the effective flotation of coarser particles (Kohmuench et al., 2018). Fluidised bed flotation is advantageous as it can reduce the need for finer grinding, reduce grinding costs, and it accepts feed with very high solid ...

Conditioned pulp is pumped to the Argentite (silver mineral) flotation circuit. The three stage flotation circuit will recover floatable silver minerals remaining in the primary leach residue. Two banks of 4100 cu. ft. rougher flotation cells must recover as much of the silver mineral as possible within the 30 minutes allotted contact time.

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.

The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit.
