Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores leaching. An ore is a type of rock that contains minerals with
normally each ore is different from another relative to the exposure of the valuable mineral targeted, for example gold is free at size range from 10 to 25mm in highly oxidized ore. and a recovery of around 70% can be reached . However I suggest you do several column test for different sizes to obtain the best recovery at the least cost.

properties. For example, iron ore, mineral sands, coal, and diamonds are some minerals that use at least one of these extraction processes. The product can then be further upgraded by chemical (hydrometallurgy) techniques. meTallurgical TesTing for iron ore
hydrometallurgy, extraction of metalfrom oreby preparing an aqueous solution of a salt of the metal and recovering the metal from the solution. The operations usually involved are leaching, or dissolution of the metal or metal compoundin water, commonly with additional agents separation of the waste and purification of the leach solution and the precipitation of the metal or one of its pure compoundsfrom
Traditional hydrometallurgical extraction processes include acid leaching to recover metals. HNO3 /HCl/HClO 4 /H 2 SO 4 was used for extracting Cu, Pb, Zn, etc. Aqua regia (AR) was also used for nonselective and aggressive digestion of BMs (Cu, Pb, and Zn) and PMs (Ag and Au) from WEEE.

Feb 16, 2020 The leaching process uses an aqueous solution to extract metal from the ore. The solution that is used specifically in hydrometallurgy is named as the lixiviant solution. It may have different pH values, oxidation-reduction potentials, chelating agent composition, temperature and other properties depending on the type of metal we are going to extract. These reaction conditions are
