Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through threestage crushing and thus segregated by screening into 1040 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has been ...

Direct reduction (DR) of iron ore with hydrogen is a potential route for nearzero CO 2 steelmaking, but vertical shaft DR reactors require that iron ore fines must first be pelletized. This study reports an investigation of the pelletization and subsequent sintering behaviour of titanomagnetite (TTM) ironsand, which is the main iron ore feedstock for New Zealand's steel industry.

Grinding tests were conducted on an oxidized coppercobalt ore using a pearshaped ball mill. Twelve monosized ore fractions were prepared and wet ground batchwise. The mill was run for to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
