Safer Frother Option for Coal Flotation A Review

Australia, for example, each state government places a different set of mining regulations. These regulations are continuously getting stricter on items allowed in mine sites. Many metallurgical processes require the use of hazardous chemicals which could create hazards while in transport, use and disposal.

Froth flotation Wikipedia

Mar 04, 2005 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 great enabling technologies of the 20th century.

Frothers & Froth Flotation ArrMaz

Frothers & Froth Flotation. The importance of frothers in mineral flotation is widely acknowledged in the mining industry. Frothers perform the following key functions in the froth flotation process: Reduce surface tension of the liquid-gas interface to enable froth formation; Hinder coalescence in order to stabilize bubble size

Frothers such as pine oil and Dowfroth 250 are used to create a froth capable of carrying or holding the mineral-laden bubbles. Frothers impart a temporary toughness to bubbles prolonging life until they can Pine oil and its relative reagent eucalyptus oil (used in Australia), are mixtures of terpene alcohols such as Terpineol, Borneol

The use of blends of alcohol and glycol based products (such as F170-F190 series) are growing in popularity as it offers the best opportunity of obtaining the optimum froth for the circuit, especially for balancing the needs between good metallurgical performance, operating ease and cost.

However, bubble coalescence is a natural consequence of the extraction process due to the reduction in the frother concentration. It is concluded that the prospects for economic frother extraction from flotation tailings are relatively weak, with a stage-wise recovery of 14% at a feed flux of only 0.7 cm/s.
