Abstract
The article presents data of experimental studies into magnetic properties of iron-bearing sulfide and nonsulfide minerals under radiation and heating. It is found that bulk magnetic susceptibility has increased more than 100 times in pyrite and by 6 times in bauxite ore. Usefulness of radiation-and-heating magnetization in modification and processing of bauxite and tin-bearing minerals is demonstrated.
