pyrite in zinc ore flotation in iran

Mar 15, 2021 A representative sample of sphalerite flotation concentrate was obtained from Bama lead/zinc mine (Isfahan, Iran). Pure specimens of pyrite were obtained from Sarcheshmeh copper mine (Rafsanjan, Iran). The concentrate was characterized in terms of elemental compositions, mineralogical analyses, particle size distribution.

Selective separation of galena and sphalerite from pyrite

In this research, the selective flotation of galena and sphalerite minerals was evaluated from a pyrite-rich lead-zinc sample. An optimum mixture of selective collectors against pyrite and also organic/inorganic pyrite depressants was obtained in the flotation of galena and sphalerite by an experimental mixture design. The effect of different collectors and pH values were investigated in the ... Learn More

The effect of flotation desulfurization on the trace

Jun 01, 2021 Thirty-seven years of mining and processing of Cu-porphyry ore has been resulting in the production more than 540 million tons of waste tailings in Sarcheshmeh industrial complex, Iran's largest Cu producer. The main objective of this study is to evaluate the changes that occurred in the trace elements content of Sarcheshmeh mine tailings during the flotation desulfurization process ... Learn More

Depression of pyrite in the flotation of high pyrite low

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. Pyrite was significantly depressed with these bacteria using the optimum dosage of reagents. Sphalerite recovery and Zn grade in the obtained sphalerite concentrate were both enhanced by ...

Lead Zinc ores Danafloat

The zinc concentrate is actually the tails from this bulk separation step. The flotation tailing is the zinc concentrate. If the silver is associated with the galena, the silver reports to the lead concentrate. While pyrite is fairly easy to depress with lime, pyrrhotite is more difficult to depress. Learn More

Gold Pyrite ores Danafloat

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 … Learn More

Yaser Kianinia Iran Professional Profile LinkedIn

In the current study, the effect of pulp pH and the collector type parameters on the galena and sphalerite flotation from a complex lead–zinc–iron ore was investigated. The ethyl xanthate and Aero 3418 collectors were used for lead flotation and Aero 3477 and amyl xanthate for zinc flotation. Learn More

Flotation Behavior of Complex Sulfide Ores in the Presence

Jan 01, 2017 Base metals such as copper, lead, and zinc are mainly extracted from sulfide ores. Mostly these base metals tend to exist together in an ore. Flotation process is widely used to separate these minerals in sulfide ores [1]. A wide range of chemical reagents are used in the flotation process to separate the different minerals. Learn More

Pyrite Depression in Multi Metal Flotation Borregaard

Pionera F-250 improved the grade of lead, zinc and silver concentrates by pyrite depression in a plant trial. At the Endeavor mine in Cobar, NSW, zinc and lead with silver concentrates are produced. Reduced production volumes towards end-of-life made traditional ore blending techniques unavailable to control the amount of pyrite in the final ... Learn More
