Kongolo, 2003), attention has been focused on the effect of chem-ical variables on environmental desulphurization of different mine tailings In the present study, the effects of operation conditions such as the froth depth, air ﬂow rate, impeller speed and pulp density on desulphurization of MT are investigated 2 Experimental 21
Frothers are liquids that produce the froth or on which the flotation process depends The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and non-flowing
Apr 30, 2012· The results from pilot scale flotation tests on an Outokumpu flotation unit are presented, which confirm that froth flotation is effective to reduce sulphide contents of tailings The factors affecting the treatment effectiveness, such as the froth depth, air flow rate, pulp density ,
The ore being treated has both free gold and gold associated with pyrite Quite simply stated, if the pulp density is not maintained at 30% or higher by weight, it is very difficult to keep the coarser free gold into the froth phase Copper sulfate is often used as an activator for promoting free gold flotation
