Limestone was used as an additive to adjust the slag composition for lowering the slag melting point. The ferronickel product was recovered by means of a magnetic separator from semi-molten slag and metal after water quenching. To increase the efficiency of magnetic separation, a large particle size of ferronickel is desired.

The magnetic mineralogy of a limestone is difficult to describe optically because of the small grain size and low concentration; magnetic techniques are more convenient. Direct analysis of extracted magnetic minerals is handicapped by the difficulty of obtaining a representative extract. A particularly useful technique involves combined ...

Magnetic resonance imaging (MRI) is used to quantify in situ the recovery of crude oil from a strongly oil-wet microporous limestone core-plug. We demonstrate the capability of low-field MRI to continuously monitor oil saturation distribution by obtaining a series of spatially resolved transverse relaxation time (T 2) distributions using the robust …

A magnetic polarity sequence has been developed for the Late Cretaceous from about 500 stratigraphic samples of the Scaglia Rossa limestone from a 250-m thick section near Gubbio, Italy. Although a large soft component is present in all samples, it is possible to remove it by alternating field magnetic cleaning.

Magnetic separation uses magnets to attract magnetic substances, while gravity separation exploits differences in the specific gravity of materials.
