Recovery Of Copper From Dust

"AN IMPROVED PROCESS FOR THE RECOVERY OF COPPER

Several investigators have studied hydrometallurgical processes for recovery of copper from copper dust. Reference may be made to K. Jia Jun, Q. R. Yun and C. Chia Yung, Hydrometallurgy, 14, 1984, pp 217-224, wherein it is described that copper dust is leached with sulphuric acid under atmospheric and high pressure to recover metallic values.

Ways to Recover Metals from Electronic Waste

05/12/2012· This involves use of Acids to dissolve and recover metals from E-waste. This process is mainly followed in China, India and Asian countries where E-waste gets exported form developed nations like US, UK and Australia. It can mainly recover metals like copper, gold, lead and iron from E-waste like printed circuit boards, used mobile phones etc.

Efficient removal and recovery of arsenic from copper

25/01/2021· Abstract. The efficient removal and recovery of arsenic from copper smelting flue dust have received widespread attention due to its extremely high toxicity and carcinogenicity. In this research, a roasting method used for treating the dust at a relatively low temperature (300-400 ℃), with adding sulfuric acid and bitumite, was proposed, in

SULPHATION OF CUPROUS AND CUPRIC OXIDE DUSTS AND

Copper smelting with the Outokumpu flash smelting process generates significant amounts of SO 2-rich off-gas and flue dust. From the smelting unit, gases with a dust load are directed into a heat recovery boiler (also known as a waste heat boiler). In the radiation section temperature decreases, sulphates become thermodynamically stable,
