agglomeration of iron ores and concentrates

US4465510A - Agglomeration of iron ores and

A process for improving the compressive strength of iron ore agglomerates, such as pellets or briquettes, used as a feed to an iron blast furnace, in which the particulate iron ore is treated, either before or after agglomeration with sufficient liquid or gaseous iron pentacarbonyl to provide about 2-5% carbonyl iron on the surfaces of the iron ore particles, following decomposition of the ...

Agglomeration Of Iron Ores And Concentrates

Agglomeration Of Iron Ores And Concentrates. Abstract.Low-grade iron ores are finely ground and processed to recover iron-bearing minerals.However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called pellets.

2017-12-20  Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...

Biomineralization of metal-containing ores and concentrates

Biomining is the use of microorganisms to extract metals from sulfide and/or iron-containing ores and mineral concentrates. The iron and sulfide is microbially oxidized to produce ferric iron and sulfuric acid, and these chemicals convert the insoluble sulfides of metals such as copper, nickel and zinc to soluble metal sulfates that can be readily recovered from solution.
