Dry Magnetic Separation Recovery Iron from Steel Slag Powder

recovery and rational utilization of steel slag powder. Introduction Steel slag is a by-product in the production of iron and steel, its main compositions are dicalcium silicate, tricalcium silicate, metallic iron, ferric oxide, etc[1]. At present, the ratio of utilization of the steel slag is only 50~60 wt. % [2].

CHROMIC: NEW PROCESSES TO RECOVER METALS FROM

to recover Cr and V from stainless steel and FeCr slag materials based on alkaline leaching [2, 3]. A potential route towards alkaline heap leaching of SS slag and FeCr slag was developed on lab scale whereby NaOCl was added as an oxidizing agent [4]. Within CHROMIC, VITO will use microwaves as well to improve the efficiency

Recovery of metal values from copper slag and reuse of

12/1/2017· According to them, using a two-stage flotation process, 80–87% Cu can be recovered from the copper slag. Using additives with ground copper slag, Guo et al. (2016) performed re-melting followed by flotation and magnetic separation to recover Cu and Fe. They indicated that a slow cooling of the molten product helped in enhancing metal recoveries.
