separation of gold from copper

Copper-Lead-Zinc ores

Other factors related to the specific copper and lead mineral processing characteristics must be considered when deciding on which copper or lead mineral will be floated from the other, for instance relative mineral flotation kinetics. The subsequent Cu-Pb separation flotation step is usually conducted at alkaline pH regardless.

Oleic acid can also be used as a collector for gold-copper oxide ores. The greater the difference of solubility of Metal Xanthate in a cyanide solution, that is, the greater the difference of Ki/n, the easier the separation of two metal minerals in the cyanide solution. Gold, silver and xanthate form insoluble xanthate.

Extracting Gold | HowStuffWorks

This causes gold to collect on the negative terminals. ­Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers ...

Eliminating Copper from Gold Ore

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 ...

Abstract. Thioureaformaldehyde (TF) and ureaformaldehyde (UF) chelating resins were synthesized and these resins were used in the separation of gold (III) ions from copper (II) and zinc (II) base metal ions. In the experimental studies, the effect of acidity on gold (III) uptake and gold (III) adsorption capacities by batch method, and loading and elution profiles of gold (III) ions, gold (III), copper (II), and zinc (II), dynamic adsorption capacities and the stability tests of TF and ...
