So if you want to learn about froth flotation you39ll love this post nbsp.
Froth flotation method is a kind of gold mining process that makes the useful minerals adhere to the bubble for achieving the gold separation with the flotation reagents based on the difference of physical and chemical properties of mineral surface The froth flotation method can be used to deal with the nonferrous ores such as copper lead zinc sulfur and molybdenum Some ferrous metals rare metals and some nonmetallic ores such as graphite apatite are also separated by the froth flotation method.
Froth flotation method is one of the most widely used methods for treating pulse gold ore in gold concentrator In most cases froth flotation method is used in the treatment of gold bearing ores with high reproducibility of sulfide minerals with good separation effect nbsp.
The froth flotation process can not only enrich maximum gold into the sulphide mineral concentrate but also discard the tailings so the processing cost is low Besides froth flotation method can also be used to polymetallic gold mining such as gold copper gold lead gold antimony gold copper lead zinc sulfur ores For this kind of ores the froth flotation method can effectively identify and select various gold bearing sulfide concentrates which is beneficial to the comprehensive recovery of mineral resources nbsp.
In addition for so calledquotrefractory oresquot that cannot be treated directly by amalgamation and cyanidation a combined process including froth flotation method is also required Of course the forth flotation method also has its limitations It is difficult to obtain stable flotation foam after mixing for coarse embedded and gold ore with particle size greater than 0 2 mm and for quartz gold ore without sulfide so the froth flotation method is difficult to be adopted.
In recent years the froth flotation method used in the gold mining has made great progress which is mainly reflected in the innovation of technological process the development of new reagents the improvement of design and so on nbsp.
Using step grinding step separation process is the development trend froth flotation method used in the gold mining at present Most gold mining plants in foreign countries usually use two or even three stages while some gold mining plants in China adopt two stages grinding two stages separation process The gold recovery is increased by 2 6 Changing the reagent system and using a variety of mixed reagents to improve the gold mining effect.
The froth flotation method used in the gold mining mainly includes.

Sep 02 2020nbsp018332Mineral amp Ore processing is the largest application of the froth flotation equipment market owing to increasing demand for good ore grades in the industry across the globe.
Jul 26 2020nbsp018332It is utilized when gold is present in the ore as coarse particles This occurs when one finds gold along with sulfide minerals such as pyrite Recovering the gold from sulfide concentrates will often require further processing but froth flotation can make a notable difference It is equally possible that gold is recovered as a by product.
