The impact of water quality on flotation performance SAIMM

water quality in minerals separation processing. Whilst consideration of pulp chemistry has encompassed solution assays and species affecting pH, Eh and some precipi tation, a systematic and comprehensive approach to modelling the behaviour of solution species integrated with their effect on mineral surfaces is not normally undertaken.

Sedimentation and flotation tests reveal that conditioning can effectively remove chlorite slimes from pyrrhotite surfaces, resulting in an enhanced flotation recovery of pyrrhotite. When mixed minerals were conditioned under the natural atmosphere, a faster conditioning speed and longer conditioning time decreased the flotation recovery of pyrrhotite.

of copper minerals including copper oxides, carbonates, suldes (with the exception of chalcopyrite) and native copper are highly soluble in cyanide solutions [2]. These copper containing minerals are problematic because, when ores containing such minerals are leached with cyanide to recover the gold, copper also dissolves to

A recovery of 99.6 pct of the copper was obtained from the head solution with a utilization of 69.7 pct of the scrap added. A similar test made on minus 10 mesh scrap, also shown in table 4, indicates substantially lower copper recovery and scrap utilization than the minus 35 mesh material.

This material is referred to as pregnant leach solution. Oxide copper minerals are very soluble in the leach solution. Sulfide minerals are rendered soluble by certain bacteria that feed on the sulfide minerals and convert them to soluble sulfates and other soluble forms. This biological action tends to maintain the acidity of the leach solution.

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
