Mar 04, 2019 · CSIRO Team Leader, Dr David Miljak, said the ore sorter is likely most suited to the copper mining industry as it can detect these minerals at extremely low grades. He believes the processing costs for a big mining operation will drop radically for each pound of copper or ounce of gold produced – as much as 20% in some mines

The ore sample is a low-grade gold bearing refractory copper ore, in which, gold is closely associated with copper-sulfur minerals, the gold( mainly in nature gold) are distributed in the gaps. After the ore was dissociated, a large part of gold became granular gold, and it was difficult to achieve effective recovery by flotation, so the

Jun 13, 2017 · ORE SORTING BY SINK-FLOAT for Pre-Concentration. As yet not applied to the sorting of gold ores, this method is extensively used for the elimination of low-grade material in the treatment of coal and various “metallic” and “nonmetallic” ores. Based simply upon the principle of “floating” the waste in a heavy media suspension having

The difference between this kind of gold ore and the third kind of gold ore is that gold has a low grade, but can be used as one of the main comprehensive utilization elements. The natural gold in ore is medium size and the symbiotic relationship between gold and other minerals is complex. For this kind of gold ore processing, most of the gold is concentrated in copper concentrate and the gold is recovered during copper …
