Abstract:

For the gold concentrate which bearing high copper and lead，We use alkalization and oxidation before eyanide leaching．Adding two typies of leaching agent selected from experiments，can obviously improve leaching enviroment and gold leaching result，reduce the consumption of cyanide 1．1 kg／t．

Key words: Gold concentrate bearing copper and lead, Leaching rate, Leaching agent, Alkalization
