Peter Hayes, Pyrometallurgy Innovation Centre (PYROSEARCH), School of Chemical Engineering, The University of Queensland, Australia. Abstract Copper feed streams chemistries continue to be increasingly complex due to the growing metal demand, corresponding shortage of primary sources and increasing recycling.

Arsenic in copper flash smelting (FS) systems not only affects the quality of products but also poses significant technological and environmental problems. Based on the assessment of arsenic mass partitioning in the FS system, arsenic elimination in off-gassing and tailings is 22%, and most of the arsenic output (69%) is recycled in the FS system. Circulating …

Within this paper, application options, the environmental behavior, and ways to treat copper slag in order to remove hazardous and recover valuable metals are critically reviewed.

For example, Li et al. [12] used LCA to compare the environmental impact of precious metal and copper recovery from electronic waste by three processes: (1) pyrometallurgy, (2) chemical leaching with conventional chemicals, and (3) chemical leaching with a novel copper leaching technique. We consider scenarios 2 and 3 to both be ...

A critical review of the pre-processing and metals recovery methods from e-wastes. Rima Kumari, Sukha Ranjan Samadder, in Journal of Environmental Management, 2022. 4.1 Pyrometallurgical process. Pyrometallurgical process is a traditional approach of metal recovery where, different thermal treatments such as incineration, roasting, sintering, …

This process consumes 2,500 to 3,000 kWh · t –1 of copper produced. The copper is deposited on the cathode and the gases produced at the anode (O 2, Cℓ 2) are recovered selectively and returned to the process. This method produces an extremely pure copper that can then be rolled (hot or cold), drawn or even formed into tubes before being sold.

In the last 75 years, the pyrometallurgical industry worldwide has made great strides in this direction. For example, Weidenhammer [] has provided a history of development of Metallurgy in Canada since 1900.Diaz et al. [] have provided a history of innovation in pyrometallurgy in Canada between 1960 and 2011.Dalvi and Bacon [] …

Pyrometallurgy is an extractive metallurgy field that uses high-temperature techniques to extract and purify metals, alloys, or mattes from primary ores and/or secondary resources. Because operating temperatures frequently near 1500°C, pyrometallurgical processes are difficult, high-risk, and energy-intensive.

Pyrometallurgy is considered to be an environmentally friendly technology in processing of primary and secondary raw materials. The continuous development of pyrometallurgical processes to treat more complex raw materials requires direct support from fundamental research. In this reprint, 18 papers focusing on recent investigations into the existing and …

Abstract. The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel. Plant operations may be either batch, semi-continuous, or fully continuous to produce blister copper or other end product.

In this work, we used life cycle assessment to compare the environmental impact of four copper and gold recovery processes. We evaluated pyrometallurgy, chemical leaching, and bioleaching, as well as a hybrid leaching process that uses bioleaching to recover copper and chemical leaching to recover gold.

Conventional methods to extract copper from sulfide ores using pyrometallurgy have been used for decades and about 75% of primary copper is recovered using these methods [I]. Even though conventional processing is highly efficient, the depletion of clean copper sulfide ore reserves requires new strategies to extract the copper with certain ...
