Review on Extraction Methods of Valuable Metals from Copper Smelting Slag
摘要
Abstract
With the rapid development of China's copper industry,a large amount of copper smelting slag is produced every year,and how to deal with copper smelting slag has attracted widespread attention.Copper smelting slag has high copper and iron grades,and al-so contains valuable metals such as zinc,cobalt,nickel,etc.It is a kind of high value-added secondary resources,which is difficult to treat due to its complex mineral structure,and most of the copper slag is mainly piled up,occupying a large amount of land resources.Therefore,in order to fulfil its potential economic and environmental benefits,copper smelting slag needs to be recovered and treated metallurgically,rather than being dumped or discarded without treatment.This paper introduced the current situation of comprehensive recovery of copper smelting slag in China,and gave an overview of three methods of extracting valuable metals from copper smelting slag,namely:flotation,pyrometallurgy,and hydrometallurgy.Water-quenched and slow-cooled slag aspects of flotation were discussed.The reduction and roasting,melt oxidation,and melt sulphation aspects were analyzed for pyrometallurgy while chemical and bioleach-ing were used to analyze the hydrometallurgy with detailed advantages and disadvantages of these various methods.The merits and de-merits of each method were analyzed.The comprehensive utilization path of copper smelting slag was also suggested to achieve the re-covery of valuable metals and the reduction and elimination of bulk solid waste simultaneously.关键词
