Abstract null null We have developed various types of jigs for resources recycling focusing primarily on plastic-plastic separation. The RETAC jig could be used to separate plastics heavier than water (specific gravity (SG) > 1.0) with different SGs while the hybrid jig—a process combining jig and flotation—was developed to separate plastics with similar SGs but different surface wettabilities. Meanwhile the reverse jig—a RETAC jig with a top screen—is used to separate plastics lighter than wate...

Abstract null null The motion of particle-laden bubbles is common in the gas–liquid-solid three-phase process like flotation. In this study, the motion of particle-laden bubbles in the stagnant deionized water was obtained by high-speed dynamic imaging. The experimental ranges of the mean bubble diameter and particle diameter were 2.76–3.95 mm and 58.2–196.35 μm, respectively. Results show that the terminal rising velocity decreases with the increase in the diameter of covering particles and the...

Abstract null null Given the geographical imbalance distribution and supply shortage of rare earth elements (REEs) in renewable energy processes, magnets, many high-tech technologies, etc., researchers are increasingly seeking to recover REEs from unconventional sources such as coal and coal by-products. This article provides a brief overview of the REEs mode of occurrence and its association in coal. It also discusses existing and potential beneficiation strategies for enriching REEs from coal ...

Abstract null null Recycling of waste electrical and electronic equipment (WEEE) is attracting increasing attention, due to the presence of valuable metals and the risk of environmental emissions associated with WEEE disposal. In this study, the distributions of trace elements (Ag, Ni, Co, and Sn) between copper alloy and magnetite/wustite-saturated iron silicate slags were investigated at 1200–1300 °C and PO2 of 10-10-10-6.5 atm, simulating the conditions of WEEE reprocessing through secondary ...
