ore processing units contain a large quantity of solid particles in suspension heavy metal ions flotation reagents organic matter etc Chen et al. 2009 . The tailings from the industrial flotation circuit in plant 2 of a gold mining company are discharged into the tailings dam at a rate of 41 Mt/year. Studies are being conducted on
1.Gold-bearing sulfide ores with fine gold particles and good flotability. 2.Polymetallic gold-bearing sulfide ores and carbonaceous ores. 3.Insoluble ores which can not be processed directly by mercury mixing or cyanidation a combined process including flotation is also needed to achieve the best results.
In the process of this flotation Reagent Which In Use Is a form of lime bubble and collectors. Froth forming a bubble that is stable and that float to the surface as a froth flotation cell . Collector reagents react with the surface of the precious metal sulfide mineral particles making the surface is water repellent . surface of the mineral
If the gold is combined with the copper than if your current grade is 0.8 g/t grade to raise this you need to reduce the overall recovery and lose copper. If the gold is separate than you need to adjust the scavenger and re-cleaner circuits to get more recovery of the gold by adjusting the reagents. Note you may lose copper doing this also .
Z. Xu Z. Zhou in Reference Module in Chemistry Molecular Sciences and Chemical Engineering 2013. Concluding Remarks. With generations of research efforts flotation has matured into a process of choice for many separation tasks including mineral separation bitumen extraction from tar sands soil remediation materials recycling de-inking de-oiling de-colouring biological species
There are many that affect the gold flotation process such as particle size flotation reagent system pulp density flotation time agitation intensity inflatable volume pulp temperature etc. In order to achieve better flotation effect all parameters must remain optimal value for the flotation process.
For the inhibited minerals flotation process the dosing sequence of the flotation reagent should be: activator flotation collector foaming agent. 4. Flotation Reagent Dosing Method. There are two dosing methods of flotation reagent. One is to add flotation reagents in once time and the other is to add flotation reagent in batches.
A general overview of gold processing steps. Flotation tailings are obtained as by-product and huge amounts of flotation tailings are present in the world. Especially old flotation tailings contain more gold content due to overage and inefficient processing methods. The amount of gold in tailings depends on the feed.

Gold and silver are recovered by gravity concentration cyanidation or flotation from ores. The choice of those processes depends on the mineralogical characterization as well as gold and silver contents of the ore. Flotation has been applied on ores containing free gold and silver particles for many years.

Through gravity separation flotation machine extraction of metals from ores and then the appli ion of mineral reagents through chemical methods and finally after smelting the final product into finished gold processing. Gold ore is a mineral aggregate with sufficient gold content and can be used industrially.
Flotation process can maximum enrich gold to the sulfide mineral tailings can be abandoned directly the cost of processing plant is low 80% of China& 39;s rock gold are used in this method. Flotation process that mainly including dosing mixing filling blowing foam etc .It is a high technological enterprise that integrated research
Flotation in mineral processing method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to. Froth flotation - Wikipedia
the process and remarkable development taken place in flotation technology and its ancillary systems it has now become possible to recover fine grained sulphide minerals from complex ore deposits whose processing was earlier considered un-economical. Today about 400 million tons of sulphide ore is treated annually by flotation process worldwide.
Handbook of Flotation Reagents: Chemistry Theory and Practice is a condensed form of the fundamental knowledge of chemical reagents commonly used in flotation and is addressed to the researchers and plant metallurgists who employ these reagents. Consisting of three distinct parts:
