 Jambreiro Pilot Plant Confirms High Purity DRPF Concentrate
Key Points
  • Over half a tonne of high-grade DRPF concentrate produced with average product specification of 67.8% Fe, 1.45% silica and 0.48% alumina
  • Product delivered with a mass recovery of 40.3% and a metallurgical recovery of 89.3%
  • Testwork supports the ability to produce a consistent, high-purity product attractive to off-takers
Full Summary

Centaurus Metals is pleased to report highly encouraging results from its recent pilot plant test work program on ore from the 100%-owned Jambreiro Iron Ore Project in south-east Brazil, confirming the potential for the project to produce a high-quality direct reduction (DR) pellet feed product across its entire projected mine life. Over half a tonne of high-grade DR concentrate was successfully produced from the pilot program with an average product specification of 67.8% iron, 1.45% silica and 0.48% alumina (silica + alumina of 1.93%) achieved. This specification comfortably meets the requirements for a DR quality product. The product can be converted into DR pellets and used as a primary ingredient in DR furnaces and electric arc furnace steelmaking - a technology that produces steel at considerably lower carbon emissions when compared to traditional blast furnace and basic oxygen furnace processes. The testwork program has allowed the Company to deliver a robust process flowsheet to support the production of the DR product and has shown areas where capital costs can be reduced from the original process flowsheet design. Tails testing has also been very positive, with results showing that the small volume of slimes tails generated can be blended with rougher spiral tails, self-drained and co-deposited with mine waste. The results from the pilot will now be delivered to potential off-takers for their consideration and assessment, with the Company continuing to advance the re-licensing process with the Minas Gerais environmental agency.

Guidance

The pilot plant testwork has demonstrated the ability to produce a high-grade, low-impurity direct reduction quality pellet feed concentrate product at scale with strong metal and mass recoveries.
