Pyrrhotite Depressant in Polymetallic Flotation, flotation of pyrrhotite is depressed in the,and thus magnetic, meaning that magnetic separation is a,the ground slurry into the flotation cell.
After flotation and low intensit y magnetic separation (by means of Davis tube), the final concentrate c ontained 0.37 sulphur. Flot ation weight recovery and
Most sulfide minerals are nonmagnetic and can be rejected by magnetic separation. Monoclinic pyrrhotite, however, in contrast to hexagonal pyrrhotite, is magnetic and is recovered in magnetic concentrates. Previous research (Cline and Rosas, 1975; Iwasaki, 1999) has shown that flotation can be used to remove pyrrhotite. The Marcona Mine in Peru
Sep 01, 2013· Results from the magnetic separation of Hannukainen material showed that the magnetite and the sulphur within the magnetic pyrrhotite are were both upgraded at a similar ratio. The same upgrade ratio applied to the other Northland deposits. This is because practically all identified pyrrhotite was monoclinic, which is ferromagnetic.

Mineral processing Mineral processing Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic
Pyrrhotite and chalcopyrite samples were separately crushed to minus 10 mesh, and the minus 10 mesh fractions were concentrated by dry magnetic separation. The magnetic fraction of the pyrrhotite sample analyzed 50.02% Fe, 29.75% S, 3.00% Ni and 0.36% Cu, and the non-magnetic fraction of the chalcopyrite sample analyzed 14.90% Cu, 30.55% S, 37
problem in iron ore smelting process. However, the magnetic separation of pyrrhotite from magnetite is problematic, due to their similar magnetic property and magnetic flocculation between pyrrhotite and magnetite [3]. Flotation has been commercially used as a method for removing pyrrhotite from magnetite for high sulfurous iron ores [4].
collect magnetic pyrrhotite on the magnet. This process was repeated until the magnet did not remain any more pyrrhotite. In this way, about 300 g of mineral was removed from the slurry. c. Flotation : A Denver laboratory flotation machine with a 4 L cell was used in all flotation tests. The rotation speed of the agitator was set at 1500 rpm. The

The contamination of sulfur emanating from pyrrhotite in magnetite concentrates has been a problem in iron ore processing. This study utilized froth flotation to float pyrrhotite away from magnetite using collectors of xanthate and dixanthogen. It was found that xanthate or dixanthogen alone could not achieve selective separation between pyrrhotite and magnetite in flotation.

Henan Fote Heavy Machinery Co., Ltd.is a professional manufacturer and exporter specilized in the prodution of ball mill, magnetic separator, rubble-tyred mobile crushing station, dryer, jaw crusher, Rotary kiln and other large mining machinery equipment.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Eriez Permanent Magnetic Separators require no electric power. With proper care, they can last a lifetime with very little loss of magnetic field strength. Eriez permanent magnets are supplied for a wide range of applications including dry bulk materials, liquids or
Non-magnetic pyrrhotite was less reactive in terms of its oxygen uptake and showed the best collectorless flotation recovery. Magnetic pyrrhotite was more reactive and showed poor collectorless
Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are
