Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.

Nickel is an important strategic metal resource, which plays an important role in national defense, aerospace, new energy and other fields. In recent years, low-grade nickel sulfide ore (LGNSO) has become the main raw materials for nickel extraction due to the depletion of high-grade nickel sulfide ore resources [1].However, the effect of the …
This type of magnetic separation machine is used in wet separation processes for smaller than 1,2 mm ( – 200 mesh of 30-100 %) of fine grained red mine (hematite) limonite, manganese ore, ilmenite and some kinds of weakly magnetic minerals like quartz, feldspar, nepheline ore and kaolin in order to remove impurity iron and to purify them.
Flotation tests were performed on a skarn ore to attain the selective separation of scheelite (CaWO 4) from fluorite, apatite, and silicates. Fluorite and apatite constitute common gangue minerals in scheelite ores. Due to their similar surface properties and good floatability, the separation of scheelite from fluorite is particularly difficult.

ABSTRACT Mineral and morphological characteristics of chromite ore strongly affect the separation efficiency while upgrading the low-grade deposits. Usually, chromite ore enrichment is carried out by using gravity separation due to high-concentration criterion between chromite and other minerals. However, chromite ore …
(1). Copper in copper-nickel sulfide ore mainly exists in the form of chalcopyrite, and nickel mainly exists in the form of free nickel sulfide such as fennelite and pentlandite. In addition, most of the nickel is mainly endowed in pyrrhotite in the form of similar phenomena, so the most important process of beneficiation of copper-nickel …
The magnetic separation efficiency of nickel from the laterite ore was evaluated using the recovery ratio of nickel R ni using the formula: (1) R Ni = m Ni × β Ni M Ni × γ Ni × 100 % where m Ni is the mass of the magnetic product, g; β Ni is the nickel content in the magnetic product, wt.%; M Ni is the mass of the reduction product, g ...
