newest generation fine impact gold ore flotation cell
Flotation an overview ScienceDirect Topics
Today, flotation is commonly used in the processing of primary coppergold ores to produce a copper concentrate containing gold as a co product, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron sulfide minerals.
FloatForce Upgrade Outotec
Improve metallurgical performance and energy efficiency, and reduce operating costs with a new generation mixing mechanism. By improving flotation hydrodynamics and pumping performance at high air dispersion rates, Outotec FloatForce enhances particle recovery in the flotation cell while at the same time reducing power consumption and the risk of sanding.

The zinc copper lead ore will be processed into a concentrate, while the gold silver ore will be refined into semi pure bars, called dor bars. These products are then sent to our customers for furth er refining before they can be used in mobile phones, life support devices, computers, copper wiring, solar panels, power generation, water purification systems, and many other uses.

High Intensity Air Injection Spargers Outotec
The small bubbles provide higher surface area, which is favorable for flotation kinetics. This effect has been shown in several studies. (Finch and Dobby, 1991; Gorain, 1997; Zhou, 1997) In the past few decades, the main evolution of column flotation technology has occurred in the development of new sparger systems.
New Approach for Lead, Zinc and Copper Ions Elimination in
1) d issolution of gold from ores by an alkali cyanide solution; 2) recovery or cementation of gold from the leach solution by metallic zinc powder. In 1900, the flotation process was first used for concentrate fine hydrophobic particles of gold to rising bub bles in a flotation cell and this froth process came into general use in the 1930s.

discarded as fines and slimes. In the case of iron ore, nearly 50% is wasted as fines generated either at the time of mining or during conversion of lumps into calibrated lump ore. Because of loss in mineral values in the fine size range,. consideraple interes~ is growing in developing new processes for the recovery of fine particles. One of the most widely used techniques in processing fines is froth flotation.
