and usually requires as little processing as crushing and screening. Lump ore is manly hematite. Sinter fines, usually below ca 10 mm in size, may or may not require processing beyond comminution. Gravity separation (jigging) is common for hematite, while dry magnetic (dry LIMS) separation is the preferred method for magnetite.

Application: Mainly used in the cement industry: the back-grinding coarse powder after the powder separator and the clinker pre-pulverization before the fine powder before iron removal, to prevent iron. Iron particles accumulate in the mill, thereby improving the production efficiency of the mill and the specific surface area of the cement: iron removal before the cement filling process can.
