Copper and Pyrite Separation by Selective and Sequential

Apr 13, 2016 The sulfide minerals in the ore are chalcopyrite and pyrite and the gangue is siliceous. The flowsheet is designed for the production of a high grade copper concentrate followed by the production of a clean pyrite concentrate for further treatment to recover the gold values. The copper pyrite separation

Magnetic Separation of Pyrite 911metallurgist

Feb 08, 2021 The inherent susceptibilities of coals (about minus 0.5 x 10 -6) and of pyrite (0.3 x 10 -6) do not permit an effective separation of pyrite in a large-scale operation. Present experiments indicate that an effective susceptibility >3 x 10 -6 for pyrite would be sufficient.

WO2013169141A1 Method and apparatus for separation of

A method and an apparatus for the separation of the mineral components of a pyrite containing copper- molybdenum ore by flotation. The method comprises grinding the ore in the presence of soda ash in an open circuit to produce an aqueous ore slurry; subjecting the slurry to a collective flash flotation step (10) in the presence of soda ash and sodium sulphide to recover a first part of metal

A novel depressant for selective flotation separation of

Sep 01, 2019 The value mineral in the ore is mainly pyrite and the dominant gangue mineral is pyrophyllite [1,2]. Froth flotation, a physico-chemical separation process that utilizes the difference in surface properties of the valuable minerals and the gangue minerals, is the main technique to recover pyrite from pyrophyllite and other gangue minerals at

US5171428A Flotation separation of arsenopyrite from

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO 3 ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings

Separation of feldspar from quartz using EDTA as modifier

Nov 01, 1999 Flotation responses of quartz and feldspar in 20 mg/l diamine solution (PDP) and as a function of various depressants (concentration: 5.10-4M). It can be seen in Figure 2 that it is evident the difference in floatability of minerals in the flotation cell in presence of EDTA and the best quartz feldspar separation are obtained at pH of around 2.

Separation of feldspar from quartz: Mechanism of mixed

Aug 01, 2002 高达10%返现 Using pure albite and quartz minerals, the separation of albite from quartz using mixed cationic/anionic reagent schemes is assessed through Hallimond flotation, zeta potential and diffuse reflectance FTIR studies. The reagent schemes are tested in bench-scale flotation for the separation of albite from Greek Stefania feldspar ore. The single mineral flotation tests

Developing Effective Separation of Feldspar and Quartz

Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al. [] in an acidic environment (pH = 2.1).It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a high-quality quartz [].However, there is a large amount of chemical activator (HF or NaF) in the flotation system, as

Dry Magnetic Separation of Bauxite Ore

separation, acid leaching, reduction roasting and high intensity magnetic separation on Indian bauxite ores mainly to reduce iron and silica content (Nandi 1996). A typical bauxite deposit available in Maharashtra State, India contains Fe203 and Ti02, however, can fulfil the refractory specification when these impurities are removed.

US4158041A Separation of ilmenite and rutile Google

This invention relates to a process for separating rutile and ilmenite from ilmenite leach tails and is effected by treating the leach tails from an acidic leach to a flotation step whereby gangue is separated from the unreacted ilmenite and rutile. The latter is then roasted at an elevated temperature in a hydrous atmosphere to convert the ilmenite to a magnetic material.
