electricity consumption of zinc electric arc furnace ranges from 35004300kw.h/t crude zinc depending on the zinc concentrate grade. compared with vertical retorting process zinc electric furnace smelting has better adaptability to material especially to high copperironsilica zinc concentrate and higher metal recovery rate.
the vacuum swing adsorption process has found appliion for oxygen requirements of less than 100 t/d at purities of 90%. in this technique nitrogen is removed in two molecular sieve adsorption trains connected in parallel and operating in sequence.
2019105&ensp·&ensphydrometallurgy is a method for obtaining metals from their ores. it is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores concentrates and recycled or residual materials. metal chemical processing techniques that complement hydrometallurgy are pyrometallurgy vapour metallurgy and molten salt electrometallurgy.
the treatment produces saleable products (metals) or intermediate compounds/alloys (impure metals) for further processing (refining). the pyrometallurgical process is suitable for iron ore chromite lead zinc copper tin and tungsten. pyrometallurgy follows one or more of

copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficulttoconcentrate copper oxide ore. traditional copper hydrometallurgy process typically consists of atmospheric leaching solvent extraction (sx) and electrowinning (ew). it can produce either copper hode or copper sulphate crystal.
* extraction using aqueous solution is called hydrometallurgy. * it is a preferential process. * generally low grade or complex ores are extracted using hydrometallurgy. steps in hydrometallurgy : 1. preparation of ore for leaching ( size reduct
in most instances both phases are molten (such as the matte and slag in a conventional copper smelting operation). the gas phase may also be used to advantage either as a means of separating valuable volatile constituents or for removing unwanted volatile impurities. these separation techniques form the basis of thermal smelting and refining operations.
