zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. at temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it.

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.
as in all mining operations, the ore must usually be beneficiated (concentrated). the processing techniques depend on the nature of the ore. if the ore is primarily sulfide copper minerals (such as chalcopyrite), th · text under ccbysa licenseextraction of metals from concentrated ore reduction ofafter concentration of ores, we must now extract metal from in it. this step will give us metal in its pure form i.e. the native form of metal. first, we must convert the ore to a suitable form. the metals need to be in an oxide form for the reduction process to be easier. hence the ores are converted to oxides, so it is ideal for reduction.process optimization of a chrome ore gravity concentrationprocess optimization of a chrome ore gravity concentration plant for sustainable development y. rama murthy1 and s.k. tripathy1,2 synopsis india has resources of chromite. to optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. most of these plants suffer chromite
