ammonia. The water balance is controlled by evapora-tion after the ammonia regeneration. Calcium chloride is regenerated into hydrochloric acid and the solution is returned to leaching. In total, the leaching process takes about 10 to 15 hours to complete. The leaching residue weight is about 25 percent of that of the matte fed into the process.

01-05-2007 · The detailed chemistry of the oxidative ammonia leach is quite complex and multistep, but the basic principles are reasonably established . Briefly, the sulphide component is oxidized to a soluble species, predominantly sulphate (SO 4 − 2 ) together with some lower oxidation state species such as thiosulphate (S 2 O 3 − 2 ), tri-thionate (S 3 O 6 − 2 ) and sulphamate (NH 4 SO 3 NH 2 ).
