In this study, we report our efforts to provide an integrated approach to gold leaching and recovery that is low-cost, sustainable, simple, and safe (Fig. ). In working toward this goal, we report multiple new technologies for the leaching, recovery, and purification of gold from both primary and secondary sources. A pathway for scale is considered at the outset, as well as methods to regenerate and recycle leaching reagents and novel sorbents. The featured leaching reagent is trichloroisocyanuric acid (TCCA), which can be converted to an effective oxidant by reaction with halide catalysts. TCCA is a low-cost compound widely used in water chlorination and disinfection, and as an oxidant in chemical synthesis . We hypothesized TCCA would be an effective and convenient carrier of chlorine for oxidative dissolution of gold, with the potential for regeneration using chlorination methods already established in TCCA manufacture . Additionally, we report two new sorbents that are highly selective for gold, even in complex mixtures of metals. These sorbents are polysulfide polymers, both derived from low-cost elemental sulfur. These sorbents serve a dual purpose: they quench the active oxidants in the leach solution and bind to gold. In one case, a novel continuous flow photochemical ring-opening polymerization was invented to access a linear polysulfide that can bind to gold (Fig. -S20), and then be thermally depolymerized to recycle the regenerated monomer. Finally, an operationally simple gold refining technique is described that coordinates the novel TCCA leaching method with reductive precipitation of gold by ascorbic acid. Following demonstrations on real-world samples of ore, e-waste, and other secondary sources of gold, a discussion is provided on the prospects of uptake in different sectors.
