Several processes have been developed to treat cyanide bearing effluent, these occasionally being derived from cyanide used as a flotation reagent but especially derived from cyanide use in gold extraction .
Flotation Reagent In Ore Washing Optimal Performance. However, the reagent dosage control based on human experience can easily cause fluctuation of the performance index, which may result in wasted ore resources and chemical reagents. in this paper, a control method of reagent dosages based on bubble size characteristics is proposed.

In each case the ore was ground to about 70 per cent minus 200 mesh and conditioned at 22 per cent solids with the reagents as indicated. Flotation reagents included reagents 301 and 208 and pine oil. In the second case some soda ash and copper sulphate where also used. GOLD FLOTATION FLOWSHEET
Tomamine flotation reagents unique properties make them ideal for reverse flotation, which is the process of selectively removing impurities during ore flotation by taking advantage of differences in hydrophobicity and zeta potential.

The flotation reagents can be added in a feed forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear based sensors have been tried with success.
Among the flotation reagents, commonly used activators for flotation are sulfuric acid, sulfurous acid, sodium sulfide, copper sulfate and so on. Inhibitors: It is a kind of reagents mainly used to increase the hydrophilicity of minerals and to form a hydrophilic film on the surface of the ore particles in flotation process. At the same time, it inhibits the action of the collector on the mineral and reduces the floatability of the mineral.
The AFW is a limiting curve indicating the possible ash and sulfur that could be achieved using froth flotation technology. Note that the packed column provided both low ash and sulfur; however, the Microcell and Jameson cell both provided high combustible recovery. Sign in to download full size image Figure 7.
Flotation has become one of the most important techniques available for mineral processing. This work reviews sulphide mineral collector properties, their manufacture and use with specific ores. Emphasis is placed on the different flotation mechanisms involved in particle capture of sulphide and non sulphide minerals and the effect of antagonal mechanisms on reagent selection.
