The separation of arsenic from copper in a Northparkes copper–gold ore

In order for the high-arsenic regions of the Northparkes copper–gold orebody to be beneficiated economically, tennantite ((Cu,Fe) 12 As 4 S 13) present in the ore needs to be rejected to enable copper concentrates to meet the typical smelter penalty level of 2000 ppm As. Using a composite sample of high-arsenic drill cores from Northparkes it was possible to …

Significant increase in gold recovery using Jameson Cell flotation

Gold losses during flotation often occur within the fines fraction, which has been an ongoing issue that has challenged the gold mining industry. Subsequently, operations will attempt to coarsen up the primary grind to reduce the fine gold (free gold or sulphide gold) generation, resulting from over grinding. Under-grinding can then to lead to gold losses in the coarse …
