Nickel Ore - an overview | ScienceDirect Topics

The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled dust. Roasting is carried out in rotary kilns (~3 m in diameter, ~75 m in length, with a hot zone length of 9 to 12 m in the case of lean ore ...


enriching the nickel content of the ore. This is com-monly carried out by magnetic separation, Sotation, or a combinationof both after the ore is comminuted to below 200 m in size. The enrichment depends upon the degree of rejection of the other sulRde and non-sulRde gangue. The maximum grade of nickel achieved by Sotation is around 28% Ni.

Segregation roast process for the recovery of nickel from ...

Sep 09, 1975· Nickel or nickel alloy may then be recovered from the ground calcine by any conventional method, such as by magnetic separation preferably using a low intensity wet magnetic separator, froth flotation, tabling, heavy media separation, leaching, organic heavy liquid separation or other methods of ore dressing.

Nickel Metal: It's Properties, History, Production & Uses

Jul 28, 2019· The separation process for nickel is highly dependent upon the type of ore. Nickel sulfides, such as those found in the Canadian Shield and Siberia, are generally found deep underground, making them labor-intensive and expensive to extract. However, the separation process for these ores is much cheaper than for the lateritic variety, such as ...

Separation of Nickel From a Nickel Ore - Prezi

Smelting The Product Waste Issues ISSUE: discarded slag from the smelter and other impure waste from the leaching and electrolysis processes. MANAGEMENT: Storage of waste in dumps and tailings ponds. ISSUE: Sulfur dioxide is a major air pollutant emitted in roasting, smelting,


Nickel sulphide ore subjected to this investigation was taken from the Marmara district of Turkey, where widespread chromite mineralization can be observed. Some amounts of magnetite and chromite exist in the ore together with sulphide and oxide type nickel minerals. The ore sample contains 1.32% Ni, 10.79% SiO2, 78.39% Fe2O3, 1.3 g/t Ag, and 1.0 g/t Au.

Assaying Nickel Determination Methods

It must be remembered that the nickel and cobalt so obtained are derived from a fraction only of the speise yielded by the ore taken, so that the results must be multiplied by the weight of the whole of the speise, and divided by the weight of the fragment used in the determination.
