effective grind ability of iron ore

Iron ore grindability improvement by microwave pre-treatment ...

However, based on energy saving alone, microwaving to improve the grindability of the iron ore was not cost effective. By improving the grindability, changes occur in the grinding circuit that may decrease comminution costs. If the iron ore is easier to grind, there would be less wear of the mill, mill liner, and milling medium.


This complex sequence is not cost effective for many low-grade ores that are resistant to physical concentration. For example, many ores contain iron oxide in a nonmagnetic form and are so fine-grained that it is uneconomical to grind them to a fine enough size to separate the iron oxides from the gangue.

Increasing the grind size for effective liberation and ...

However, the ability to exploit microwave-induced fracture by improving flotation recovery and grade, and/or increasing the primary grind size to effect liberation has significant potential benefits in terms of increasing plant throughput and metal production while reducing metal specific energy consumption, even without significant reductions in ore competency.

Beneficiation of Iron Ores – IspatGuru

For beneficiation of a particular iron ore the emphasis is usually to develop a cost effective flow sheet incorporating necessary crushing, grinding, screening and beneficiating techniques which are necessary for the upgrading of the iron ore. A typical flow sheet for iron ore beneficiation plant is shown in Fig 1.

Crushing and Grinding Process - JXSC Machine

The ore material with less than 80 mm and more than 20 mm has poor grinding ability, and it is not easily broken by large ore materials, sometimes When the material is crushed, a steel ball of about 4% to 8% of the volume of the mill is often added to the mill, which improves the grinding efficiency of the mill, and thus semi-self-grinding occurs.
