Froth Flotation and Frother 911 Metallurgist

2016-12-19  Frothers such as pine oil and Dowfroth 250 are used to create a froth capable of carrying or holding themineral-laden bubbles. Frothers impart a temporary toughness to bubbles prolonging life until they canbe removed from the cell. There are three ways that a particle can move or be transported from the pulp phase into the frothphase:

Froth Flotation and Frother 911 Metallurgist

2016-12-19  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 carrying or holding the mineral-laden bubbles.

How Frother Affects Flotation 911 Metallurgist

2021-7-1  For example, Table VI demonstrates, using MIBC frother as a base, that increasing the molecular weight of the Dowfroth family decreases the value of R but increases the associated K values. Thus the Dowfroth family offers a wide spectrum of frother capability ranging from DF-200 giving a high R value and low K to DF—1012 giving a high K value

The results show the complexity of the process and also suggest that a more detailed understanding of the action of the frother is required.

2019-8-19  The response of ores to higher molecular weight frother Dowfroth 250 has showed that in spite giving higher recoveries, the frother gave poor grades on both ores. The poor grades given by Dowfroth 250 can be attributed to formation of highly stable froth enhanced by fine gangue (mica) and gangue entrainment caused by higher water recoveries.
