Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on …
Nickel Deposits Explained Magmatic Nickel Sulphide Deposits The bulk of nickel mined today comes from either nickel laterite deposits, in deeply weathered terrains where nickel is released from the weathering of ultramafic rocks, or from nickel sulphide deposits which is our primary focus at Grasset.

What of Ni/Cu processing facilities? Similar techno/economic to considerations make typical nickel producers unsuitable Only mixed nickel/copper sulphide capacity is suitable •Ni laterite unsuitable due to copper contamination in the PGM concentrate •Norilsk and Jinchuan have declined our feed in the past
As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding. Then a Cu-Pb bulk concentrate is recovered with xanthate, dithiophosphate and flotation reagent blends.
The Nickel Mining Process. Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most well-known purification processes is called the Mond Process, which is an extracting and ...
Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high
The dried agglomerated ore is then fed to the rotary kiln with the addition of reductant coal. In the kiln, the ore is completely dried, calcined to remove chemically-combined moisture, and the iron and nickel oxides are partially pre-reduced. Kiln dust is recycled to the process at the primary crushing stage ahead of the dryer/agglomerator.
The effect of salinity on the processing of various nickel laterite ores is discussed. In particular, the presence of . high concentration chloride, sulphate, sodium, calcium and magnesium is addressed. Key unit process operations affected by these ions include ore preparation, pressure acid leaching, counter-current decantation and product
Nickel laterite ore is one of the main primary sources of nickel which contributes to about 70% of world land- based nickel resources [Dalvi, D.A. et. al. 2004]. In term of processing route, the ...
The source of the sulphur in these ore bodies is either from the magma itself or from the pre-existing rock where it was present as sulphate. The most common nickel mineral in these ores is pentlandite, (Ni,Fe) 9 S 8. The atomic ratio of nickel to iron in pentlandite ranges …
upgrading of the mined ore rejects hard, precursor rock using the techniques of mineral processing, such as crushing, grinding and screening. The precursor rock is generally low in nickel and cobalt. The nickel content of the ore might be doubled during upgrading. Method of Extraction from Saprolite Ore
The primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy ...
metal ores (<1% copper, <1g/ton gold, < 0.5% nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009).
