Effect of Using a Frother for 'Froth' Flotation - YouTube

The most commonly used frothers are generally the compounds of carbonyl group, hydroxyl group, amino group and a carboxyl group. Alcohol-based frothers are the best type of frother. Frothers can be divided into two parts. 1. Natural frothers examples – Pine Oil, Cresol etc. 2.

Froth Flotation

In this work, a combination of batch flotation tests and froth stability measurements was used to optimise the collector and frother scheme for the flotation of a copper ore. The methodology was applied to an Australian copper plant which was experiencing high variability in froth stability in the roughers when the feed ore mineralogy was changing.

Frothers - an overview | ScienceDirect Topics

Frothers play an important role in the flotation process, for example in preserving t he size of bubbles after their generation and increasing the stability of the foam, among other purposes.

Froth Flotation Process - Detailed Explanation With ...

Nov 01, 2011· Rougher flotation results for the concentration of a copper sulphide ore in a Denver cell with biosolids or a salt of humic acids as both collector and frother indicate that these materials have potential to substitute conventional chemical collectors and frothers used in the industrial flotation of sulphide minerals in Chile.

Dithiophosphate Aqueos (MC-208) Has excellent selective properties for copper ore flotation and an excellent collector for gold, silver and copper. Collector Blend (MC-347E) Partially water soluble and widely used in copper sulphide ore flotation, particularly when a secondary mineralization of molybdenum or silver exists.

The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a ...

Flotation tests using the reagents as frothers for copper-molybdenite sulfide mineral are conducted to determine the metallurgical performance of these potential frothers. The metallurgical performance of the flotation is also used to confirm the potential frothers selected by …

Selectivity and power of frothers in copper ore flotation

Frothers Certain product mixtures are particularly useful as flotation reagents; specifically collectors in the flotation of molybdenumbearing copper ores, where molybdenum recovery has been increased by more than 10% without adverse effects on copper recovery. Use as a collector in most base and precious metal flotation circuitsget price

Froth Flotation Process - Detailed Explanation With ...

Two types of depressants carboxymethyl cellulose (CMC) and guar gums which are usually used in the flotation of PGE bearing ores were used. The frother was Dow 250. Results showed that increasing either guar or CMC dosages from 50 to 100 g/t enhanced the recovery of copper and nickel sulphides.

The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance ...

INVESTIGATION OF EFFECTIVE PARAMETERS FOR …

The experimental evidence supports the hypothesis that in porphyry copper flotation the grinding environment influences surfaces oxidation, pyrite activation and the extent of hydrophobic particles reporting to the froth phase. This has an indirect effect on the resulting froth stability, which is however small if compared to the other factors.

Effect of Using a Frother for 'Froth' Flotation - YouTube

Lime is often used in flotation to increase the alkalinity of the pulp. An alkaline pH increases the volume of the froth (possibly increasing the rate at which mineral is recovered), and depresses pyrite. Frothers such as pine oil and Dowfroth 250 are used to create a froth capable of …
