There is a compelling need across several industries to substitute non‐degradable, intentionally added microplastics with biodegradable alternatives. Nonetheless, stringent performance criteria in actives’ controlled release and manufacturing at scale of emerging materials hinder the replacement of polymers used for microplastics fabrication with circular ones. Here, the authors demonstrate that active...
A new hydrometallurgical leaching process, which dissolves lead concentrates with acidic ferric methanesulfonate solution, was proposed and investigated. The leaching kinetics of galena-containing concentrate from Red Dog Mine (Teck) was studied with respect to variables such as stirring speed, temperature, concentrations of free acid and ferric ions as well as particle size. It was found that stirring...
Cerussite (PbCO 3 ) concentrates may be recovered from oxidized lead ores. A hydro-electrometallurgical process to treat cerussite concentrate by methanesulfonic acid (MSA) is proposed. Cerussite concentrate was first leached with MSA. The parameters of temperature, stirring speed, acid concentration, particle size and solid to liquid ratio were considered in this study. After the primary...
