Leaching of Pyrite by Acidophilic Heterotrophic Iron

Seven strains of heterotrophic iron-oxidizing acidophilic bacteria were examined to determine their abilities to promote oxidative dissolution of pyrite (FeS 2) when they were grown in pure cultures and in mixed cultures with sulfur-oxidizing Thiobacillus spp. Only one of the isolates (strain T-24) oxidized pyrite when it was grown in pyrite-basal salts medium.

Recycling of iron from red mud by magnetic separation

Jul 20, 2014· A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with pyrite (FeS 2).TG-DTA and XRD results showed that hematite was reduced to magnetite by the thermo-decomposed compounds (iron monosulfide, pyrrhotite and element sulfur) of pyrite.

An Innovative Approach to Separate Iron Oxide Concentrate

Aug 01, 2016· High-sulfur and low-grade pyrite cinders are the waste products of sulfuric acid manufacturing plants. Many valuable components, such as iron oxide, are contained in pyrite cinders and difficult to be separated and purified just via the high temperature roasting process. Considering this, an innovative method including water-washing, aqua regia leaching, hydrothermal alkali activation

Reduction Roasting of Tin-Bearing Iron Concentrates Using

A novel method of reduction roasting of tin-bearing iron concentrates using pyrite (FeS 2) is proposed, in which hematite in tin-bearing iron concentrates is reduced to magnetite (Fe 3 O 4) and cassiterite (SnO 2) is transformed to volatile tin sulphide (SnS).In a certain range, tin removal and iron reduction rates both increase with roasting temperature, pyrite amounts and residence time.

How to Separate Gold from Pyrite

So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier. Nevertheless, as this gold comes under the head of non-amalgamable gold, its physical state and the causes of its disinclination to unite with mercury may conveniently be considered here

How Iron Pyrite is Formed | Actforlibraries

Iron pyrite is a fairly common mineral, and is mined or extracted globally for its many industrial uses, such as extraction of the sulphur for sulphur dioxide or sulphuric acid, and also as an ore for iron. It oxidises readily, making it easy to extract the component minerals, but care must be taken as this also makes it quite combustible.
