Iron ore (fines)
Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3 ), goethite (FeO (OH)), limonite ...

Pelletization Solutions
As high-grade iron ore deposits become more limited, it is necessary to upgrade lower quality iron ore resources through concentration. The ground iron ore must be pelletized prior to feeding into a blast furnace or DRI plant. Our pelletizing equipment is designed to produce pellets of highest quality at the lowest cost.

Froth Flotation Process
The process of froth flotation usually involves a series of steps: the preparation of appropriate particle sizes of liberated components in the mixture of solids to be separated; the creation of conditions favourable for the adherence of one or more components in the mixture of solids to attach to air bubbles; and.
Direct reduced iron process
The process gases carbon monoxide ( CO C O) and hydrogen ( H2 H 2) are blown into the furnace at temperatures of approx. 1000 °C and flow through the iron ores. The reduction of iron oxides takes place according to the following chemical equations: Fe2O3 Fe2O3 + 3CO + 3H2 → 2Fe → 2Fe + 3CO2 + 3H2O (1) (2) (1) F e 2 O 3 + 3 C …

The six main steps of iron ore processing
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.
A Detailed Look at Iron Ore Agglomeration
Iron Ore Agglomeration Tests. All lab tests are designed around the distinct qualities of each material, and thus the sample's characteristics should be acknowledged prior to testing. Overall, iron ore is: Heavy. Abrasive. Dusty / easily wind-blown. Varying in composition (some samples contain more clay than others).
