Study of the possibility of iron extraction from waste coal by magnetizing roasting

[摘要] The efficiency of magnetizing roasting of waste coal in converting iron, contained in the mineral part, from weak-magnetic and non-magnetic minerals (siderite, pyrite, marcasite) into high-magnetic ones (magnetite, maghemite) is shown. Products of magnetizing roasting are used as raw material for the subsequent magnetic separation.
