Anionic flotation of high-iron phosphate ores—Control of

01-07-2009· The data suggest that the use of guar gum especially for flotation of high-siderite phosphate ores should offer improved flotation results. However, the kinetics of phosphate flotation was significantly slower in the presence of guar gum and longer flotation times were necessary to obtain phosphate recoveries similar to those for starch.

Flotation of Gold and Gold-Bearing Ores ScienceDirect

01-01-2016· A great deal of work has been reported on specific ores, but such studies rarely distinguish between the flotation of native gold and other gold minerals. Flotation of gold ores covers a broad field, and it is a rather difficult subject to generalize on. Most problems in gold ore flotation are not connected with floating metallic gold.

1 Froth Flotation Fundamental Principles

1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air

Recovery of PGMs from an oxide ore by flotation and leaching

Froth flotation is the process used in the Platinum Group Metal industry to upgrade the run-of-mine ore for subsequent processes such as smelting and hydrometallurgical PGM refining. The PGM concentrator plants achieve high PGM recoveries (>85%) when treating prestine (unweathered) sulphide ores.

THE FLOTATION OF HIGH TALC-CONTAINING ORE FROM THE

The ore is mineralogically similar to that of Merensky reef in South Africa, but differs in that it contains high concentrations of talc. The lower recovery (of typically around 79%) is partly a result of the high concentrations of talc. Talc is naturally hydrophobic and therefore tends to float and report to the concentrate. During the experimental

08-06-2016· The quantity of promoter depends on the character and amount of mineral to be floated, and in general for sulphide or metallic minerals .01 to .20 lbs. per ton of ore are required. Flotation of metallic oxides and non-metallic minerals usually require larger quantities of promoter, and in the case of fatty acids the range is from 0.5 to 2.5 lbs. per ton.

Flotation of Iron Ore: A Brief Review MDPI

30-07-2020· This is why reverse anionic flotation of iron ore using oleic acid or its soaps is usually performed in a strongly alkaline environment (i.e., above pH 11). Fuerstenau and Cummins [28] concluded that, when oleate was used as collector, the suitable pH value was between 11 and 12 in the flotation of quartz. Table 2.

"Dolomite flotation of high magnesium phosphate ores

The separation of dolomite from apatite has been recognized as one of the most difficult subjects in mineral processing due to the similarities in their physiochemical properties. In this study, selective surfactants were used with a fatty acid soap collector to improve the flotation performance of separating dolomite from high magnesium phosphate ores.;Three surfactants, diethyl phthalate (DP

A study on selective flotation in low and high pyritic

The effect of chemical reagent configurations was investigated on two different copper sulphide ore types, including high and low pyritic feeds. Three different combinations of collectors as isopropyl-n-ethyl thionocarbamate (C-4132), mixture of mercaptobenzothiazole and butyl sodium dithiphosphate (Flomin 7240) and sodium isopropyl xanthate (Z11) were used in flotation experiments.
