Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium to highgrade (+62% Fe) and are directly used in blast furnace and in directreduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and agglomerated pellets (Iron and SteelVision, 2020).

The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the highgrade ores depleting very fast, the focus is on the beneficiation of lowgrade resources. However, most of these ores do not respond well to the conventional beneficiation techniques used to achieve a suitable ...

Openpit mining differs from quarrying (with the possible exception of iron ore) in that the valuable mineral constitutes only a small proportion of the total tonnage of rock produced. In quarrying, the rock itself is the valuable commodity, with virtually all of the raw rock that is won being processed (often only by crushing and screening) to ...
