Ore Dressing Methods

Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or wet methods). Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk.

Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them. The ore is first ground into fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt.

Iron ore beneficiation: an overview

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 high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …

From Ore to Iron with Smelting and Direct Iron Reduction

In the smelting reduction process, pelletized iron oxide ore or fine ore powders are pre-reduced in a fluidized bed or reduction shaft. The reduced iron along with coal and lime is fed to a gasifier-melter, which completes the reduction process and produces pig iron or hot metal of the same quality as a blast furnace.
