Pressure hydrometallurgy has attracted much attention for its characteristics, such as the high adaptability of raw materials and environmental friendliness. Flashing (flash boiling or flash evaporation) refers to phase change phenomenon from liquid gas triggered by depressurization, which is an important connection between high-pressure processes atmospheric ones in pressure hydrometallurgy. T...

the recovery process of selenium from iranian sar-cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. the copper anode slimes are made up of those components of  the anodes, which are not soluble in the electrolyte. they contain varying quantities of precious metals like gold, silver, selenium and tellurium. they are being extracted as a by product in the co...

The exponential growth of electric and hybrid vehicles in the last five years forecasts a waste problem when their batteries achieve end-of-life. Li-ion for have been assembled using materials from natural resources (as Li, Fe, Al, Cu Co, Mn P). Among them, LiFePO4 cathode demonstrated advantages such as charge–discharge cycles, thermal stability, surface area raw availability (against Ni Co sy...

Waste water purification is shown to be an important field of environmental hygiene for non-ferrous metal industries. Hydrometallurgy becomes of greater importance for metal production and refining. Quality standards for drinking water and rivers require a minimum of some harmful impurities, e.g. metal compounds. The unit operations of hydrometallurgy technologically parallel the methods of eff...
