Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
Depression of pyrite in porphyry copper flotation Ian Wark Research Institute Australian Research Council Special Research Centre For Particle and Material Interfaces
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 concentrate should be considered. Producing a pyrite concentrate with associated gold maximizes gold recovery.
Dec 16, 2016 Abstract: Froth flotation of copper-zinc-lead ores is a complex process Flotation can be defined as a physical-chemical process that allows for separation association of chalcopyrite, galena and sphalerite, with pyrite, quartz and carbonates . metal recovery and concentrate yield (weight recovery).

Depression of pyrite in the flotation of high pyrite low-grade lead–zinc ore using Acidithiobacillus ferrooxidans
In this research work, selective depression of pyrite in the flotation of a low-grade lead–zinc ore containing 31% pyrite was investigated in the absence and presence of Acidithiobacillus ferrooxidans.
zinc and pyrite (recovering of gold and silver) from the bulk flotation tailings was used based on the ore characteristics. The concentrate indexes of the grade of copper, lead, and zinc …

Froth Flotation (Sulphide & Oxide) ... We are running flotation Sulfide Lead & Zinc ore type that has high dosage of pyrite in that ore. We depress pyrite with cyanide but it has a dangerous EHS effect that we want to eliminate it. What's your suggestion in order to replace this kind of reagent for pyrite depressant?

Pyrite is the main raw material for industrial sulfuric acid, but China is a leading manufacturer and consumer of sulfuric acid, so the comprehensive utilization of pyrite plays an important role in lead-zinc tailings recovery. At the same time, improving the recovery of pyrite in non-ferrous metal sulfide ore has the good influence on the whole national economy and mining enterprises.

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.
we have gold in pyrite ore, we extract this gold by flotation, but some time we have with our ore kaolinite clay which interfere with gold in flotation and give and give us bad gold … Get Price Separating the Magnetite Mining Pyrite by the Flotation ...
The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
