Unlocking maximum value saleable tons from iron

2021-5-4  Commissioned in late 2017, the two CDE processing plants wash, separate and gravity beneficiate about 17 Mt of low grade overburden iron ore that was stockpiled in waste dumps into a high-grade saleable product with a 63% iron content upgraded from an average low-grade grade of between 45% and 50% iron content in the waste dumps, explains Warren.

Iron Ore ScienceDirect

Waste gases from iron ore fine preparations for blast furnace ironmaking, or sintering, contain minute quantities of acidic species, dust, and dioxin pollutants, but because of the very large quantities of iron ore processed and the large volume throughput of air involved, sintering is a major source of these emissions and also CO 2 into the atmosphere.

Treatment and Recycling of the Process Water in Iron

The annual processing capacity of iron ore reaches 22 million tons, and the wastewater from mineral processing is about 400 thousand m 3 every day. If the dressing wastewater is directly discharged into the nature, it will not only pollute the surrounding environment but also has a great potential safety risk.

Green Processing of Iron-Based Materials

Currently, 10% of iron ore ends up as steel mill waste that amounts to 100 million tons annually. Furthermore, there exist numerous waste streams that are potential sources of iron including spent iron oxide catalysts (e.g. from styrene and ammonia synthesis), red

Characterization of Chromite Ore Processing Residue

The test results revealed that major phases of COPR were CaCO 3, iron/chromium containing spinel, and SiO 2. Concentrations of iron-containing phases, calculated as Fe 2 O 3, ranged from 10 to 33% by weight. The COPR samples from nine sites can be divided into two groups, one with high concentration of iron oxide (20–33%) in a form of spinel having magnetic property, and another with low concentration of iron

XRD, FTIR, and thermal analysis of bauxite ore

The present work shows the results of X-ray diffraction (XRD), Fourier transform infrared (FTIR), and thermal analysis of untreated (RM nt) and acid-treated red mud (RM a), a bauxite ore-processing waste, exchanged with Pb 2+, Cd 2+, and Zn 2+ cations. These studies were performed in order to investigate the changes in the sorbent structure caused by the exchange with metals of different ionic radii.

Unique chemical helps salvage iron ore from mining

“Some iron ore processing plants in the Pilbara experience issues separating valuable iron ore from undesired materials in wet processing situations,” Professor Leong said. "We have demonstrated a more efficient way of extracting iron ore from waste, which will reduce material thrown away in tailings dams and save millions of dollars per year."

Reuse of iron ore mineral wastes in civil engineering

2008-9-1  The iron ore is predominantly mined by opencast mining throughout the country. The solid material generated in large quantities by iron ore extraction is the material that overlies the ore body and the processed tailings . These wastes contain minerals associated with the ore body and host rock, mainly the laterite, and sometimes the clays.
