Introduction Flotation machines constitute the basic equipment for useful minerals recovery from nonferrous ores and other raw materials by flotation. They can operate also as individual flotation cells. Flotation Cells (Froth Flotation) were developed to separate and recover highvalue Sulphide ores from lowgrade ore bodies.

Coppergold: Flotation: Aerofloat 3477 in the cleaner scavenger circuit improved the recovery of tarnished flaky gold. Particlesize (20 to 100mm) free gold floated rapidly in first three rougher cells; 5 to 20mm gold particles floated at slower rate; coarser gold (>100 mm) was recovered in first two rougher and last rougher scavenger cells20

This complete process plant is for recovering gold by gravity concentration and froth flotation. This commonly applies, but is not limited to, ore deposits containing GRG gold and sulphide minerals rich in gold (such as: Pyrite, Copper). This process will also recover silver associated with sulphide minerals. This simple metallurgical concentrator includes single stage crushing, conveying ...

Flash Flotation of Gold The Outokumpu flash flotation concept as an approach for precious metals recovery. Concerns were: Could a concentrate be recovered from coarse, high solids cyclone unflow. Would the proposed flash flotation machine operate on 2 continuous basis or would machine be down frequently because of plugging.

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.

Lime (in the form of calcium oxide, CaO, or calcium hydroxide, Ca (OH)2) is a very common modifying reagent. Modifying reagents react either with the mineral surfaces or with collectors and other ions in the flotation pulp, resulting in a modified and controlled flotation response ( Bulatovic, 2007a). More specifically, lime is categorized as ...
