A novel depressant for selective flotation separation of pyrite and …

2019/9/1 · The separation of pyrite and pyrophyllite by froth flotation is difficult because pyrophyllite (the three sheet phyllosilicate) is naturally hydrophobic, easy-sliming, and easily transports to flotation concentrates, thus reducing pyrite concentrate grade [2,, , , ].

Pyrite depressant useful in floation separation - FUERSTENAU; …

The present invention relates to a process for separating pyrite from sulfide ores and coal during flotation separation which comprises the depressing of pyrite with from about 0.05 to 0.75 kilograms Pyrite depressant useful in floation separation - FUERSTENAU; DOUGLAS W.

Effect of sodium hexametaphosphate on separation of serpentine …

Sodium hexametaphosphate disperses serpentine slime very well. It is widely used in mineral processing as a flotation regulator and has been applied in the separation of serpentine sulfide ore. Furthermore, there are a number of studies reporting the mechanism of sodium hexametaphosphate.

Pyrite - Wikipedia

The mineral pyrite (/ ˈpaɪraɪt /), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S 2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, …

Selective separation of galena and sphalerite from pyrite-rich …

Consequently, selective separation of lead-zinc sulfide minerals from pyrite requires appropriate selective depressant and collectors. Different reagents are usually applied in the selective separation and depression of iron sulfide minerals; they include inorganic

Kinetic Studies of Sulfide Mineral Oxidation and Xanthate …

Sulfide minerals are a major source of metals; however, certain sulfide minerals, such as pyrite and pyrrhotite, are less desirable. Froth flotation is a commonly used separation technique, which requires the use of several reagents to float and depress different sulfide minerals.

FLOTATION SEPARATION OF ARSENOPYRITE FROM PYRITE - …

In many parts of the world, pyrite and arsenopyrite occur together in sulfide ores either as the only sulfide minerals or in conjunction with other valuable sulfides. It is desirable to produce separate concentrates of the various sulfide minerals, including pyrite and arsenopyrite so that the contained desirable metals can be recovered economically.

(PDF) Selective flotation of chalcopyrite from pyrite using diphosphonic …

Pyrite, a gangue mineral, is commonly associated with valuable base metal sulfide minerals and the separation of pyrite from these valuable sulfide minerals by flotation is difficult.

Basic principles of selecting separation methods for sulfide minerals having similar properties in complex ore concentrates | SpringerLink

It has been studied how species of pyrite and nonferrous metal sulfides influence oxidation, floatability and depression. The selected methods to separate complex ore concentrates provide for multistage flotation circuit, with recovery of rebellious species into rough concentrates and products and their separation in different cycles later on.

Pyrite Mining | Processing Equipment | Flow Chart | Cases - JXSC

Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Froth Flotation Method - JXSC Machine

This froth flotation method is used to treat quartz sulfide ores or gold-silver-bearing pyrite and pyrrhotite containing gold telluride, pyrrhotite, chalcopyrite and other sulfide minerals. The floatable gold telluride in the ores is first produced as a concentrate, and then roasted and cyanided to expose gold and silver ores in sulfides and tellurides.
