Jasperoid

Jasperoid is a rare, peculiar type of metasomatic alteration and occurs in two main forms; sulfidic jasperoids and hematitic jasperoids. True jasperoids are different from jaspillite, which is a form of metamorphosed chemical sedimentary rock, and from jasper which is a chemical sediment.. Sulfidic jasperoids are typical examples of silica-sulfide metasomatism of dolomites, and are found in Get price

Minerals Engineering Manuscript Draft Manuscript Number

auriferous pyrite flotation is 9-10 because of dolomite existence in this material, as shown in Fig. 3. pH 9 was further used for all flotation tests. As shown in Fig. 3(a), using SIAX alone as collector and Terpenic oil as frothing agent, better auriferous pyrite flotation could be achieved when the SIAX concentration is higher than 40 mg/L.

gold pyrite froth flotation separation

Gold Flotation - Mineral Processing Metallurgy. Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold. Get price

Bacterial Oxidation of Refractory Sulfide Ores for Gold

Sep 27, 2008Pilot- and commercial-scale bioleaching processes for gold-containing pyrite and arsenopyrite ores are reviewed. This application of mineral biotechnology competes favorably with pressure leaching and roasting processes, both of which are problematic and energy-intensive alternatives for pretreatment of auriferous pyrite/arsenopyrite ores.

Queensland gold

The 20cm reef on the Diana Lease contained pyrite and a little free gold; on the Campbell and Buthen Buthen leases Shepherd saw only shallow trenches and small shafts. At Companimano Creek, 6km south-south-west of Buthen Buthen, a quartz reef 90cm to 1.2m wide contained gold, galena, pyrite Get price

Synvolcanic and syntectonic gold mineralization at the

The veins of zone 5 contain pyrite, chalcopyrite, sphalerite, bornite, magnetite, rutile, and gold in a gangue of quartz, carbonate, white mica, and chlorite. Disseminated auriferous pyrite occurs in zones 3 and 5.Mineralogical and textural features indicate that gold emplacement and associated alteration occurred during two events, one Get price

Remobilization of gold from a chalcopyrite

Native gold was formed during the latest, decreasing-temperature phase through remobilization of auriferous pyrite. Microprobe analysis confirmed that gold and copper are relatively enriched in the late pyrite. Identified surface-alteration products include goethite, limonite, gold Get price

US6210648B1

A method is provided for flotation of refractory auriferous sulfide using an oxygen-deficient flotation gas. The method is particularly suited for non-selective flotation of different iron-containing sulfide mineral species. Comminution prior to flotation may be performed in an oxygen-deficient environment.

Can pyrite bear some gold ? : askgeology

The presence of pyrite may have played a role in terms of destabilising gold complexes that were present in the water, changing it from Au(HS)₂ to Au whereby it can precipitate out. This is not a process that occurs in isolation though, there's all sorts of chemical reactions going on during metamorphism and hot fluid movement through rocks. Get price

Fimiston Open Pit Super Pit Gold Mine

Free gold undergoes floatation to produce an auriferous pyrite concentrate. It is then roasted to recover the gold from the tellurides and pouring the dore bars. Crushing, grinding, froth flotation and gold recovery are carried out at the Fimiston plant while roasting is performed at the Gidji plant. Get price

Paleobotanical Field Trip To The Sailor Flat Hydraulic

Nearly 70 species of ancient plants have been described from what paleobotanists call the Chalk Bluffs Flora, or those associations of fossil plants found in the Middle Eocene auriferous gravels exposed by hydraulic methods during the Gold Rush days of the mid to late 1800s--an awe-inspiring fossil flora whose overall composition resembles a Get price

Pyrite

Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), stone or mineral which strikes fire, in turn from Get price
