Entry details
Role, as stated
SECONDARY refiner — a RECYCLER by the hub's own definition. Its parent group's description of its feed is an inventory of secondary material only: jewellery-manufacturing scrap and waste, mixed-fineness bullion, polishing sweeps, wash waters, wet and dry filing sweeps, blasting waters, spent electroplating bath effluent, used crucibles, slags and floor sweepings. No source describes it processing newly mined dore.
