Special Issue Information
Dear Colleagues,
Metal resources are more crucial than ever in current global energy transition efforts. Thus, the growing demand for critical metals has increased the price of precious metals, which has promoted interest into processing tailings to recover cobalt, rare earths, nickel, gold, silver, and platinum, among others. Furthermore, environmentally friendly metallurgical processing of these tailings could be an opportunity to remediate these deposits, particularly when they are abandoned or located near to communities, as well as to obtain new sources for metal supplies by applying the circular economy concept to tailings. However, there are still many challenges to overcome for developing a sustainable industry of metal recovery from tailings, such as (i) geochemical and micro-chemical characterization to quantify concentrations of metals and to determine the preferential host mineral for each metal; (ii) metal endowment in the tailings; (iii) the poly-metallic approach for processing and extraction; (iv) concerns about the toxicity of conventional reagents used to extract metals; (v) the large size of processing plants, which limits its use as a mobile system for different deposits; and (vi) the environmental impact of processing and the final residues produced, among others. Overcomingof these challengues could generate a good synchronicity between the economic benefits and the tailings remediation in the mining value chain.
In this regard, the folowing topics are welcome to this Special Issue: (i) novel studies and developments in advanced geo-chemical and micro-chemical characterization of metal-host minerals; (ii) new proposals on the use of alternative reagents to extract critical and precious metals; (iii) novel developments to optimize the current methods of metal extraction, including reagent recovery processes; (iv) studies focused on developing compact and mobile unit operations; (v) examples of and developments in tailings remediation; and (v) studies to support the poly-metallic processing approach and process integration, as well as life cycle assessment focused on tailing processing. Industrial experiences dealing with critical and precious metal recovery from tailings are also welcome.
