Hydrometallurgical Process an overview ScienceDirect
Hydrometallurgical processes allow to obtain as final products base metals (Cu, Zn) and salts of critical metals like yttrium and europium oxalates with high purity that could be sent to the market or sold to companies for refining From: Waste Electrical and Electronic Equipment Recycling, 2018Traditional 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 WEEEHydrometallurgy an overview ScienceDirect Topicshydrometallurgical operations These include: 9 difficulties in solid tliquid separation 9 effect of impurities on the ease of purification 9 The principal disadvantage of hydrometallurgical operations is probably the process times required to achieve high metal recovery since these processesStages of Hydrometallurgical Processes

Hydrometallurgy involves the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materialsThis process is used in extraction of less electro positive or less reactive metals like gold and silverIn addition to the previously discussed processes, many ores are processed using the hydrometallurgical method, including uranium, gold, silver Figure 61 illustrates the layout of these systems and highlights specific points where certain technologies can achieve or facilitate one of the stages in the process (see shaded boxes)hydrometallurgical processes in general Industrial Hydrometallurgy, extraction of metal from ore by preparing an aqueous solution of a salt of the metal and recovering the metal from the solutionHydrometallurgy science Britannica
Stages of hydrometallurgical processes
Apr 05, 2013 Process Stages• Agitation leaching :A process where the soil is slurried with the extraction fluid for a period of time When equilibrium between the metal on the soils surface and the metal contained by the solution is approached, the solubilization of the metal in the soil is slowed, and the extraction is considered to be completeIt is an auto reduction reaction The remaining reactions are hydro metallurgical processes in which the metals are extracted by converting their ores into aqueous solutions of metal compounds and reduction of these solutions using suitable reducing agents Answer verified by Toppr Upvote (0)Which step is not involved in hydrometallurgical process?Apr 05, 2013 Process Stages• Agitation leaching :A process where the soil is slurried with the extraction fluid for a period of time When equilibrium between the metal on the soils surface and the metal contained by the solution is approached, the solubilization Stages of hydrometallurgical processes
