Hydromet TechnologyThe nickel industry worldwide has traditionally smelted concentrates produced from nickel, copper and cobalt sulphide ores to make an intermediate sulphide product called matte. Hydrometallurgy has been used for refining the matte to produce high purity nickel, copper and cobalt for the market.
Commodity NickelNickel mined from lateritic ore is mined from various depths beneath the surface using large earthmoving equipment. The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground. Nickel from lateritic ore is extracted trough extractive metallurgy.

NickelNickel is recovered through extractive metallurgy. Nickel is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel appliions, 75% pure nickel can be used without further purifiion, depending on the composition of the impurities. Most sulfide ores ...

Extractive Metallurgy | Natural Resources Research ...Extractive Metallurgy. ... Previous research included coppernickelsulfide flotation and hydrometallurgical processing for recovery of highpurity iron, copper, nickel, and platinumgroup metals. Currently, ilmenite processing is conducted via gravity (spiral) separation and hydrometallurgical techniques for recovery of highpurity iron ...
copper extraction and purifiionExtracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silie, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2. Chalcopyrite (also known as copper pyrites) and similar sulphide ...
Nickel processingNickel processing Nickel processing Extraction and refining: 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 highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
Process review and electrochemistry of nickel sulphides ...Jul 18, 2013 · Abstract. Analysis of several nickel mattes from around the world shows a significant variation in their nickel and copper content. Typically, matte contains an alloy, heazlewoodite (Ni 3 S 2) and a copper sulphide various commercial methods of processing these mattes are reviewed and some of the fundamental factors that determine the choice of leaching system are discussed.
Extraction of copper from its sulphide ore.In the extraction of copper from chalcopyrites, the impurity of iron sulphide is removed as FeSiO3 in : asked Oct 23, 2019 in Chemistry by KumarManish ( points) metallurgy
Copper Ore Types: Sulfides vs. Oxides | An Investor's ...Nov 09, 2020 · Copper sulfide ores are typically the most profitable copper ore type to mine. That is because they have high copper content, and the copper .
Nickel metallurgy | Article about Nickel metallurgy by The ...Selective concentration of the ore by flotation yields copper, nickel, and pyrrhotine concentrates. The nickel ore concentrate is smelted in the presence of fluxes in electric or reverberatory furnaces to isolate the barren ore and extract the nickel in the form of a sulfide melt (matte), which contains 10–15 percent Ni.
Explain the following:Partial roasting of sulphide ore is ...Partial roasting of sulphide ore is done in the metallurgy of copper. Partial reduction of sulphide ores give copper oxide which further reacts with copper sulphide to show auto reduction. 2CuS + 3O 2 .
