- feed mill flotation
Flotation involves adding process reagents to flotation cells. This encourages the attachment of desired product to fine air bubbles. The bubbles surface and paddles scoop the froth off of the top of the cell. Product recovery rates in flotation are key to maximizing a mill's production.

Froth flotation is a process for selectively separating of 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 great enabling technologies of the 20th century.

The two aspects that have the strongest impact on a flotation circuit's efficiency and performance are metallurgical recovery and flotation cell availability. Fluctuations in feed characteristics can lead to recovery losses. The inability to handle changes in feed size and mineralogy can result in the loss of availability.

FLOTATION COST The oil-mixtures generally in use will cost from 1.25c. up to 3c. per lb. depending on the proportion of cresol and other high- priced oils used, but 1½c. per lb. will be a safe average on most oils. A consumption of 1 to 1½ lb. per ton or from 1.25c. to 4.5c. per ton of feed, say 2½c., would be a safe average.

To facilitate a steady mill feed throughout the survey period, a large stockpile of ore was made on the ROM pad to minimise the impact of changing mill feed material. The average feed grade during the survey period was 3.7 g/t Au and 0.9% S. The target mineral for flotation within the ore is pyrite, whilst gold is the economic target for recovery.

Usually, the grinding circuit contains at least two interconnected mills with material classifiers (e.g. cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill ...
