Gold Flotation - Mineral Processing & Metallurgy

GOLD FLOTATION FLOWSHEET. It is obvious that the most suitable treatment for ores carrying gold and silver associated with pyrite and other iron sulphides, arsenopyrite or stibnite, will depend on the type of association. Cyanidation is usually the most suitable process, ...

Flotation of Pyrite - Metallurgist & Mineral …

Sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation of sphalerite.

7. Flotation of Gold and Gold-Bearing Minerals 7.1. Differential Flotation of Natural and Liberated Gold. Experience has shown that free gold particles can be recovered selectively against pyrite, by keeping the gold particle surfaces as clean as possible of organic species and by removing any adhering slime particles (Klimpel, 1997).

The selective flotation of arsenopyrite from pyrite ...

Gold can be recovered through bulk flotation or selective flotation processes according to the distribution of gold in pyrite and arsenopyrite [24,25]. The selective flotation of arsenopyrite from pyrite can be realized by adding a magnesium-ammonium mixture depressant [26].

Natural pH is recommended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation …

Pyrite-Gold Recovery in Copper Rougher Flotation Tailings

regrinding and aeration on the separation of pyrite from gold in copper rougher flotation tailings (0.07% Cu , 0.61g/t Au, tail grades). An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotation.

Optimisation of gold recovery by selective gold …

At high pH, selectivity of gold against pyrite was possible with a number of collectors. However, there was no selectivity against chalcopyrite in the flotation tests performed. Increasing the pH using lime showed no gold depression. Fine gold was easily floated while some coarse gold reported to the flotation …
