Any iron that is chemically tied up with other metals will probably not provide a satisfactory feed for the simple magnetic reduction roasting technique considered today. In general the type of ore that would be treated by magnetic roasting is not listed as measured ore reserves especially in certain areas of the country where taxes are levied on any ore reported.

Magnetic Separation and Iron Ore Beneficiation – IspatGuru

Magnetic separators are integral part of the low grade iron ore beneficiation systems. Roasting of low grade iron ores to increase their magnetization (i.e. hematite to magnetite conversion) extends the applicability of conventional magnetic separators. Magnetic separators are also used in certain iron recycling applications.

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores. More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation. The concentrate is mixed with other materials to facilitate the process. The technology is useful but is also a serious source of air pollu…
