Abstract
The experimental test data on magnetic properties of iron-bearing mineral waste materials under radiation-thermal treatment are presented. It is found that the volume magnetic susceptibility of pyrite- and arsenopyrite-containing waste has increased by 5 times on the average. The authors demonstrate that radiation-thermal magnetization and magnetic separation allows production of KOS-3 grade tin concentrate meeting fuming process requirements from waste of Novosibirsk Tin Works.
