ammonium carbonate vs ammonium sulfate copper leaching

The oxidative leaching of chalcopyrite in ammoniacal solutions has been evaluated using electro-analytical techniques The anodic dissolution process has been established to be a seven-electron transfer process under nitrogen in ammonia–ammonium sulphate solutions and ammonia–ammonium carbonate solutions The number of electrons Muby Chemicals of Mubychem Group established in 1976 is the original manufacturers of Specialty Chemicals Pharmaceutical Excipient Fragrance Flavor chemicals Shale Gas Fracturing Chemicals in India Mubychem Group has several manufacturing facilities spread across Western India and world wide contacts and toll manufacturers

Solubility table

The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature at one atmosphere pressure Units of solubility are given in grams per 100 millilitres of water (g/100 ml) unless shown otherwise The substances are listed in alphabetical order

Copper(II) sulfate also known as copper sulphate are the inorganic compounds with the chemical formula Cu SO 4 (H 2 O) x where x can range from 0 to 5 The pentahydrate (x = 5) is the most common form Older names for this compound include blue vitriol bluestone vitriol of copper and Roman vitriol
