High-gradient magnetic-separation process. The flotation-tailings grade were separated by a high-gradient magnetic separator to obtain a magnetic concentrate yield of 22.03% (for raw ore). The copper grade was 2.06%, and the recovery rate was 31.10%. The yield of magnetic tailings was 76.32%, the copper grade was 0.64%, and the recovery rate

The NovaCell is a universal flotation machine in that it can give high recoveries of ultrafine, mid-range and coarse particles, in contrast with conventional flotation machines that have a limited range of sizes where high recoveries can be obtained. The NovaCell has been tested on a porphyry copper ore (1.0% Cu) ground to a top size of 600 µm.

3. Electric Separation. In addition to wolframite, the wolframite concentrate also contains scheelite, cassiterite, and sulfide. In addition to removing sulfide by table floatation and separating wolframite by magnetic separation, electrical separation can be used to separate scheelite and cassiterite, the resulting product is tin concentrate.

The invention discloses a simple method for extracting pentlandite monominerals. The method is characterized in that copper-nickel sulphide ore is used as a raw material, and a magnetic field of which the strength gradually increases is applied to the copper-nickel sulphide ore through a permanent magnet, so as to achieve stage-by-stage magnetic separation of the copper-nickel sulphide ore.

The separation of fine sulfides becomes increasingly difficult at fine particle sizes. Potential fine size separation methods are froth flotation and magnetic separation. 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

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 is observed. Below the transition temperature, spontaneous

Chalcopyrite has good self-induced flotability and collector-induced flotability, and has good hydrophobicity in weak alkaline and neutral environments, so the flotation separation is often used in selection processing. With the deepening of mining, low grade polymetallic refractory chalcopyrite has become an important source of copper ore.

The experiment used chalcopyrite and monoclinic pyrrhotite mixed in deionized water to simulate the galvanic interaction between the two minerals. After acting for 20 min, the chalcopyrite and monoclinic pyrrhotite were separated by magnetic separation and transferred to a flotation cell for the flotation test.

Chalcopyrite [CuFeS 2] Chalcopyrite is considered a mineral of weak paramagnetic properties having a specific magnetic susceptibility of 0.8–4.5 × 10−12 m 3 /kg [17]. Others report chalcopyrite to exhibit an antiferromagnetic behaviour at room temperature, due to exchange of p valence electrons in the sulphide ion with half-filled shells

The manual separation method is simple, convenient, low at cost. But it has low production efficiency, thus causing a great waste of resources. 9.2 Magnetic beneficiation When barite coexists with siderite, magnetite, hematite, and other iron minerals, magnetic separation is an effective beneficiation method.

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