Oxide ores, on the other hand, do not produce the same reaction heats, making necessary the use of energy from other sources for smelting. From sulfide ores. Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Types of copper ore: Oxides. As mentioned, copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade. However, in some cases low-grade copper ...
Mar 10, 2018· When mixed oxide-sulfide nickel ore is treated by the existing process for high-grade nickel sulfide ore, approximately half of the non-ferrous metals including nickel, copper and platinum group metals are lost (Kosyakov et al., 1995), resulting in low recovery of valuable metals and poor economic benefit (Senior and Thomas, 2005).
Mined sulfide ores contain pentlandite, pyrrhotite, chalcopyrite and gangue rock. A high-grade nickel concentrate is produced from these ores by the following minerals-processing techniques: (a) crushing and grinding the ores to liberate the nickel- and cobalt …
Nickel Ore Processing. Nickel ore mainly consists of copper-nickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Copper-nickel sulfide ore beneficiation methods, the most important is the flotation, magnetic and re-election is usually secondary dressing method.
