Gangue. In mining, gangue /æ/ ismercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals a
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is, the surfaces are either repelled or attracted by water. The flotation process was developed onmercial scale early in the 20th century to Mineral Flotation International Mining
The effects of silica gangue and high sulphide gangue on gold attachment were examined including the effect of surface activators potassium amyl xanthate and the possibility of depressing the effects of gangue using reagents. The results were evaluated in terms of gold recovery, volumes and grade of concentrates formed. There was no change in gold recoveries when the amount of oxide gangue

The presence of hydrophobic gangue represents a primary problem in flotation of both copper and coppernickel sulphide ore.
The presence of hydrophobic gangue represents a primary problem in flotation of both copper and coppernickel sulphide ore.
The agglomerates were then separated from dispersed gangue minerals by screening and the agglomerates dispersed in a hydrophobic liquid n pentane to liberate the water trapped in the agglomerates. The chalcopyrite dispersed in the hydrophobic liquid was
They can either depress the effect of hydrophobic gangue minerals in the ore that would otherwise report with the froth along with the desired mineral, or hold down the desired mineral while floating the undesirable gangue. Solvay has developed highly efficient and versatile sulfide mineral depressants in diverse applications.
Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing
Hydrophobic modification of mineral particles is at the heart of the froth flotation process. I show here that froth floated fluorite crystals display super hydrophobic properties: they form highly stable monolayers on flat and curved liquid
15 hours ago· The major gangue minerals ~65 are calcite CaCO 3, dolomite This is due to the uncontrolled flotation of carbonate minerals whose surfaces are already hydrophobic in the CC. The main contaminant of the floated apatite is dolomite that is responsible for the 8.18 MgO content of the cleaner concentrate. 3.2.2. Reverse Flotation of Apatite . For the reverse flotation of apatite, sulfuric
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the .. Froth flotation is a process for separating minerals from gangue by taking. Get Price. Froth Flotation Machines 911
Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water.
Abstract In this paper, the effect of gangue minerals on the hydrophobic recovery of gold is being investigated using ores obtained from the active small scale gold mining sites in Tanzania. Gold ores of different gangue contents were tested.

It was found that a significant proportion of the iron sulphide minerals had surface coverages of graphitic carbon, sufficient to impart moderate hydrophobicity in the absence of collector. A smaller, but economically significant proportion of chalcopyrite was also affected by the graphitic carbon coating.

For the last 100 years, high value minerals have been ground to a fine particle size and then separated by adsorbing reagents, known as collectors, onto the mineral surface to make the minerals hydrophobic, and attraced to bubble interfaces.
In this paper, the effect of gangue minerals on the hydrophobic recovery of gold is being investigated using ores obtained from the active small scale gold mining sites in Tanzania. Gold ores of different gangue contents were tested. The effects of silica gangue and high sulphide gangue on gold attachment were examined including the effect of surface activators potassium amyl xanthate and
Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is themonly used route in iron ore flotation. This review is focused on the reverse flotation of iron ores, consisting of reverse
However it is known that some of the gangue minerals that are associated with gold have oleophilic and hydrophobic properties and the presence of such mineral gangue in the ore may be a sourcepetition during the attachment to agglom erates. Such minerals include mainly the metallic sul phides gangue .
