Magnetic Separation of Sulphide Minerals 4 MAGNETIC SEPARATION OF SULPHIDE MINERALS range of variation in susceptibility demon- strated by the various sulphides. COPPER-FLOTATION PLANTS Macuchi, Ecuador At the mill of the Cotopaxi Exploration Co., Macuchi, Ecuador, the principal minerals are chalcopyrite, pyrite, barite, and quartz.

Magnetic Separation of Fine Mineral Sulphides

The mineral sulfides, with the exception of pyrrhotite, are either weakly paramagnetic (e.g. chalcopyrite) or diamagnetic (e.g. molybdenite). Those which are paramagnetic can only be separated using high-gradient magnetic separation (hgms) at high fields (up to 2 Tesla) and low flow rates (e.g. 1 cms-¹).

(PDF) Magnetic separation of weakly magnetic copper minerals

High Gradient Magnetic Separation of chalcopyrite and bornite, both weakly magnetic copper minerals with mass susceptibilities of about 0.1 × 10<sup>-6</sup>m<sup>3</sup>/kg and 0.2 …

Superconducting pulsating high gradient magnetic ...

Again, it is the high magnetic induction available in the SPHGMS separator that contributed to the significantly strengthened magnetic force upon fine chalcopyrite minerals and consequently to the high recovery from slurry, while maintaining a high separation selectivity to the minerals, due to the pulsation effect in the SPHGMS process.

Cobalt and Nickel Recovery From Missouri Lead Belt ...

Wet, high-intensity magnetic separation (WHIMS) was considered as a poten­ tial method for removing the cobalt-nickel mineral from the chalcopyrite con­ centrate. In anticipation of such tests, the magnetic susceptibilities were measured on four high-grade mineral specimens--siegenite, chalcopyrite, sphal­ erite, and galena.

Intensification of magnetic separation and leaching of Cu ...

The thermic decomposition as a result of interaction between microwave radiation and sulphidic minerals makes possible the magnetic separation of weakly magnetic chalcopyrite and tetrahedrite. In case of magnetic separation of chalcopyrite ore it is possible to obtain the Cu- recovery in 62.53%.

Magnetic properties of natural chalcopyrite at low temperature

Magnetic susceptibilities of natural chalcopyrite from Cu ore deposits in Oman have been measured at temperatures between 77 and 450 K and magnetic field strengths between 6 and 9 kOe. The results show typical antiferromagnetism from 450 down to 190 K, where a magnetic phase transition …

Selective flotation separation of molybdenite and ...

The magnetic properties of pyrite and chalcopyrite were improved by the increase in microwave energy and the duration of treatment to such an extent that 90% of the feed separated as magnetic...

Effect of microwave treatment on the flotation and ...

Aug 01, 2007 · The magnetic properties of pyrite and chalcopyrite were improved by the increase in microwave energy and the duration of treatment to such an extent that 90% of the feed separated as magnetic product.

(PDF) The Effect of Heat Treatment on Chalcopyrite

The results suggest that selective magnetic separation of chalcopyrite from pyrite is possible only in case of microwave treatment due to its selective effect in favor of chalcopyrite at lower ...

Comparison between the effect of microwave irradiation and ...

Magnetic susceptibility of chalcopyrite increased significantly by increasing microwave power and treatment time. Pyrite magnetism was affected only at 500 W microwave power. On the other hand, magnetic susceptibility of both chalcopyrite and pyrite increased significantly by …

Influence of microwave radiation on the magnetic ...

Jun 15, 2017 · Magnetic separation Sodium hydrogen sulfide and/or cyanides are widely used to depress arsenopyrite, and permanganates and a magnesia–ammonia mixture are used to selectively oxidize arsenopyrite to reduce its floatability,.
