The presence of arsenic in zinc sulphide concentrates is particularly harmful, because it creates problems in zinc electrolysis. The main source of arsenic in non-ferrous metallurgy is arsenopyrite (FeAsS). In oxidative roasting of zinc concentrates,

Bulgaria is a major producer of zinc in the Balkans (about 100,000 tons per year). The two zinc plants (KCM S.A., Plovdiv, and LZC S.A., Kardzhali) deliver the necessary raw materials from Bulgaria and abroad. But the zinc production at LZC Kardzhali
