| Abstract: | Waste slag from environment protection section in smelting plant is a complex material containing gold.Gold grade is about 1000 g/t,and silver grade is 500 g/t.There are copper,sulphur and carbon in it too.The wet process consisted of roasting,sulfur acid pretreatment and chlorination leaching of gold is examined.The results show that gold leaching rate is 97.95% and silver leaching rate is 79.86%. |
