Abstract

Angouran lead and Zinc FLOTATION Plant is located about 95 km away from Zanjan city. This plant is one of the largest lead and zinc concentrates producers in Iran the feed which contains two types of low and high-grade zinc ore. The high-grade feed contains more than 33% zinc and less than the low-grade one. The low-grade ore is screened into two size fractions, -2 mm and +2 mm. The -2 mm fraction goes to the Pb FLOTATION circuit. The tailing from the -2 mm fraction circuit, which contains 20-23% of zinc, is sent to tailing dams. In this research zinc was recovered from this tailings by using SULFURIC ACID.The tails sample was first calcined at 800°C for an hour and then subjected to quantitative and qualitative analysis. The results show that the sample contains 28.89% of zinc and zincite and willimite are major zinc minerals bearing.The effects of factors such as stirring rate, temperature, initial acid concentration and solid/liquid ratio, on ZINC RECOVERY were studied. The results obtained show that in the best conditions, about 91% of zinc were recovered using a stirring rate of 800 rpm, a reaction temperature of 50°C, a 30 minutes reaction time, a 100 g/l initial SULFURIC ACID concentration and solid/liquid ratio of 1/6 g/ml.
