AusIron furnace is designed to produce about 500,000 t/a of hot metal when smelting typical iron concentrates and to generate about 100 MW electric power, of which one-third is consumed by the smelter. The hot metal capacity of the same AusIron furnace can be tripled when smelting hot pre-reduced iron concentrate.
Fig 1 Flowsheet of sintering process. The iron ore fines are natural ore of size 0 mm to 10 mm. The raw mix (also called sinter mix) is made with the weighed amount of iron ore fines, limestone, dolomite, sand or quartzite fines (flux), solid fuel (coke breeze or anthracite) and metallurgical wastes (collected dusts, sludge and mill scale etc).
Zinc extraction residue, a solid waste generated from the treatment of zinc-containing dust in rotary kilns, is commonly stockpiled in steel companies for extended periods. It poses significant disposal challenges and environmental pollution risks. So far, research on the treatment of zinc extraction residues has been slow, inadequate, and sporadic. For this gap, a …
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents and solid fuel (coke).
The processing of beneficiating iron and molybdenum from mineral powder often generates a large number of tailings [1], [2].In 2022, the total amount of metal tailings in China was roughly 31–32 billion tons, of which 18 billion tons of iron ore tailings and 1.0 billion tons of molybdenum ore tailings [3].The accumulation of a large number of tailings not only occupied …
Abstract In the iron ore sintering process, it is desirable to maximize the productivity and quality of sinter while minimizing the fuel consumption for any given raw material (iron ore, flux and solid fuel) quality. However, given the complexity of the sintering process and the large number of manipulated variables, it is not practical for

1. Raw Material Preparation: The first step is to create or acquire the powdered metal needed for sintering. The powders are often produced through atomization or chemical reduction. 2. Compaction: The powder is placed into a die or mold and compacted using high pressure to create a green part. This compacted part is fragile and requires further processing …
Mix into sand and it will help bind the sand together like the clay. I was told to add it to my green sand mix as another additive allong with the clay. It will smoke a little more but it will help keep your molds clean, help hold finer datails such as fingerprints, and keep the mold from falling apart when separating the flasks.
