Sep 30, 2020· The removal of iron ion from leaching solution is critical for the recovery of value metals, with the method of choice commonly being crystallization (precipitation). This paper summarized the new improvements in iron removal by precipitation methods in recent years and proposed a novel process, magnetic seeding and separation. The new process can promote iron precipitate aggregation and ...
Jun 02, 2017· The cooled slag was then crushed, milled and separated by wet magnetic separation method. Since the magnetic properties differ for different phases, it is possible to separate each phase with the aid of magnetic separation. By applying magnetic field to the crushed slag sample, phosphorus lean and rich phases may be notably separated.
refining plants that achieve recovery rates of more than 90%, established an industrial practice in the field of e-waste recycling relies mostly on the mechanical operations and as such has remained more or less the same in the past two decades.
