The Concorde Cell is an enhanced pneumatic high-intensity forced-air flotation type of technology. Unlike agitated flotation, pneumatic flotation involves mixing the air and the pulp in a continuous stream, thereby separating contact and froth treatment zones. The Concorde Cell is a technology which produces fine air bubbles with high …
of pneumatic flotation cells over mechanical flotation cells, as well as flotation columns, for the flotation of sulfide ore were demonstrated. Test results indicated that the Cu grade and recovery for concentrates obtained when using the pneumatic flotation cell were 1% to 2% and 4%, respectively, higher than those obtained when using the ...
This is a flotation equipment in which high-speed ore slurry and air are mixed and mineralized in the spraying device, and the separation is realized in the cell. It can be divided into air suction type and compressed air type. (1) Typical air suction flotation cell is China FJC jet flotation cell series. It is mainly composed of cell body ...
A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more …
Industrial flotation plants contain a series of flotation cells, chemical addition points and re-grind mills designed to maximize pentlandite recovery and the nickel grade in the concentrate.
