The use of sodium thiosulfate modified with sodium metabisulfite effectively cleans such oxide contaminants off the sulfide minerals making them more responsive to flotation extraction. Thus, beyond making previously inaccessible ores suitable for flotation recovery ( metallic mineral oxides), the present process increases the efficiency of existing metal sulfide recovery processes.
KEYWORDS Complex sulphide; refractory ore; gold; silver; pressure oxidation; sodium hypochlorite; leaching. INTRODUCTION Gold and silver are usually associated with complex sulphide ores. The conventional straight cyanidation is used to extract the gold and silver if they occur in the boundary of the mineral particle.

Role of Sodium Sulfide – Copper Lead Zinc Ore Flotation. Table of ContentsChemistry of Sodium SulfideSulfidization Sodium Sulfide in Sulfide Minerals Flotation Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form.
Single flotation collector can not effectively extract the various valuable minerals from the complex ores simultaneously. Combined use of many collectors is one of the best ways to solve the problem, because the synergistic effect induced by the multifunctional composite chemical reagents will exert positive effect to the flotation and increase the recovery.
Copper can be extracted from nonsulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
