Jameson Cell

Jameson Cell has 100% accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.

Flotation Cells & Machines

Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous 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 high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to produce bubbles and agitated to …
