HIsarna ironmaking process - Wikipedia

The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.

Iron Ore Pelletization - FEECO International Inc.

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

Sponge Iron - an overview | ScienceDirect Topics

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.

2. Scrub. Scrub is to use the mechanical force and friction between the quartz sand grains to remove the thin film iron, bond and muddy impurity minerals on the surface of the quartz sand, and further crush the mineral aggregates that have not become monomers to achieve further purification effect. At present, there are mainly two methods for scrubbing quartz sand: rod friction cleaning and ...
