Flowsheet to Produce a Marketable Molybdenum concentrate
The bulk copper concentrate from the copper flotation circuit is sent to the bulk concentrate thickener. The bulk concentrate is pumped to the storage tank.
The rougher flotation circuit is fed with the slurry from the storage tank, and treats the slurry through one row of conventional flotation cells. A rougher concentrate is obtained which is sent to the regrinding and cleaning circuits. The tailings from the rougher flotation circuit are the final copper concentrate and are sent to thickening.
The regrinding circuit receives the rougher concentrate. The concentrate is ground to reduce the particle size. The regrinding mill works with a cyclone cluster whose overflow is the feed to the cleaning circuit. Some time, can be possible send the rougher concentrate to the 1st cleaning stage without regrinding.
The rougher concentrate is cleaned in three stages employing column cells. The last column flotation stage produces the final Molybdenum concentrate. Tailings from the first cleaning stage are processed in the rougher flotation circuit. Tailings from the second cleaning stage are processed in the first cleaning stage. Tailings from the third cleaning stage are processed in the second cleaning stage. The concentrates from each cleaning stage are fed to the next stage until obtain the final concentrate in the third cleaning stage.
The final concentrate is sent to the molybdenum thickener. The concentrate slurry is thickened and, when the thickener underflow density is high (60-65% solids) can be sent to filtration. The filter eliminates water from the thickened slurry and produces a cake that is sent to the storage bin which resends the concentrate to the drying system. The dried product is sent to the packing section.
