Purity Manganese Mine

electrolytic manganese metal is produced through an electrolytic process using manganese sulphate solutions that contain ammonium sulphate typically 35 g/l mn and ~130 g/l of (nh4)2so4.In contrast emd solutions do not contain ammonium sulphate.The resulting product is a conventional emm of 99.7% purity when selenium is added to the.
