BHP's 2 million tonne per annum nominal capacity Hot Briquetted Iron (HBI) plant at Port Hedland in the Pilbara region of Western Australia is based on FINMET direct reduction technology.
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
insufficient oxygen supply, and extensive debottlenecking of the process plant was required. From all accounts it was hard technical work and required many changes, improvements and additional capital for new equipment. The process plant is now exceeding design performance and the gold recovery is currently 72% and they are

Consequently, flotation pilot plant testing allows a digital twin (DT) to be generated by combining ore characteristics, process information, and a digital architectural platform.
The magnetic products from the LIMS, MIMS, and SLon units are combined to generate the feed for reverse flotation, which produces the final iron ore concentrate. From the plant operating results for this flow sheet, an iron ore concentrate containing 67.5% Fe was produced from a run-of-mine ore containing 30.5% Fe, at a mass yield of 35.7% to ...
In the present study a detailed characterization followed by beneficiation of low grade iron ore was studied. The Run of Mine (R.O.M) sample assayed 21.91 % Fe, which is very low grade in nature.
Fig. 1 shows a typical flow sheet of a conventional high capacity itabirite iron ore processing plant in Brazil. As previously discussed, it comprises a multi-staged crushing plant followed by grinding in ball mills and desliming stages, together with concentration carried out by reverse flotation.
The main stages of the steel making process flow chart include iron ore extraction and processing, smelting in a blast furnace or electric arc furnace, primary steelmaking in a basic oxygen furnace or through electric arc refining, secondary metallurgy for quality control and adjustment, continuous casting, as well as the final rolling and ...
Gas flow through stack is done by two fans 42 and 32 connected to ESP. The ESP 42 and ESP 32 are designed to blow 400,000 m 3 /h and 1400,000 m 3 /h of air, respectively. The main raw material for the pellet plant is iron ore, which comes as slurry from the beneficiation plant through the pipe line.
