APPARATUS AND PROCESS FOR RECOVERING A DESIRED FRACTION OF A RAW MATERIAL

Title:

APPARATUS AND PROCESS FOR RECOVERING A DESIRED FRACTION OF A RAW MATERIAL

Document Type and Number:

WIPO Patent Application WO2001066259

Kind Code:

A3

Abstract:

An apparatus (10) for recovering a desired fraction of a raw material bearing the desired fraction includes a vessel or cell (12) defining a treatment chamber (14) therein and an inlet (22) into the chamber (14) for introducing a slurry of raw material to be treated into the chamber (14). An attrition zone (16) is defined in a portion of the chamber (14) near the inlet (22) in the flow path of material introduced into the chamber (14) so that particles of the raw material are caused to impact against each other. A flotation zone (18) is defined in a distal portion of the chamber (14), in flow communication with the attrition zone (16), in which the attritioned particles are contacted with gas bubbles (26). This forms a froth phase (28) separated from the slurry by a slurry-froth interface such that the desired fraction is either selectively taken up into the froth phase (28) by the gas bubbles or selectively left behind in the slurry. The froth phase (28) flows from the (14) chamber via an appropriate outlet (36).
