GOLD RECOVERY BY FLOTATION. Tests made on ore containing $9 gold, 3.5% copper, and 45% insoluble, showed that after crushing to pass 60 mesh and treating by direct flotation, an extraction of 82% of the gold and 96% of the copper could be obtained, with
When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper ...
However, when copper minerals are present in the gold ore, high levels of free cyanide must be maintained during leaching because many common copper minerals react with cyanide, forming copper ...
gold ores. We at Hazen Research have had the opportunity to participate in the development and application of a number of gold ore processes and to review others' results from applying processes to gold ores. This experience gives us the background necessary to compare the available processes on their technical merit.
Improving the recovery of gold and copper in a CIP operation: flotation of a sulphide copper bearing ore. One detrimental effect of the changes made to improve the gold recovery was a high residual cyanide content in the CIP tails. This was overcome by the use of the Inco process at a cost of 20 cents per tonne ore treated (current cost is 35 cents/tonne) (Zimbabwe currency).
The copper metal along with any gold metal is electrowon from the eluate. The copper EW cells are conventional, similar to acid based EW copper cells in design with two exceptions: (1) the solution pH value is 10.511 in a cyanide media, and (2) membrane technology is used to prevent oxidation of cyanide to cyanate.

Gold Plant, Gold Plant Suppliers and Manufacturers we can do with copper gold ores flotation cip gold A wide variety of gold plant options are available to you, such as gravity ... Hot Selling Copper Ore Flotation Machine with Good Price for Iron Ore, Lead Zinc,.
The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.
Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carbon in pulp circuit (CIP). The reagent and utilities operating costs associated with leaching, adsorption, elution and ...
