Only one incubation step is required. Direct magnetic labeling requires a minimal number of washing steps and therefore minimizes cell loss. Highly specific cell separation reagents for direct labeling of numerous cell types with MACS MicroBeads are available for human, mouse, rat, and non-human primate cells.
2018-2-3 · Lead, zinc, and iron were recovered from jarosite residues using direct reduction followed by magnetic separation. The influence of the coal dosage, reduction temperature, and reduction time on the volatilization rates of lead and zinc and the metallization rate of iron were investigated. The results show that the volatilization rates of lead and zinc were 96.97% and …
Highlights We conducted a soil washing feasibility study at a Pb mining-metallurgy site. Soil contained heavy metals associated with lead slag fragments. Magnetic characterization of the slag shows a weak ferro/ferri magnetic response. Dry high intensity magnetic separation was successful for sands. Wet high intensity magnetic separation was effective for finer fractions.
2018-6-15 · Magnetic separation is a possible way of recovering an Fe-rich product out of solid residues from secondary lead production, given the ferromagnetic (FeS and Fe 3 O 4) or strong paramagnetic (FeO) properties of the iron phases in contrast to the diamagnetic properties of the lead phases (Pb, PbS and PbSO 4) present in these residues (Svoboda ...
