Improved method for prediction of heavy metal recoveries

1998-8-1  Sometimes, however, those strategies fail for a number of reasons and as a result cleaning targets are not met. Therefore, some soil cleaning facilities have experimented with HIMS as an alternative process step. This paper describes a prediction method based on magnetic separation techniques for use of HIMS separators in soil cleaning plants.

High intensity magnetic separation for the clean-up of a

2013-3-15  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.
