About This Project


The pilot plant is stage 1 of the new business plan for the Browns Range project. Stage 1 incorporates the construction of a Pilot Plant at Browns Range wotj a 60,000tpa capacity to produce 49,000kg dysprosium, in 590,000kg TREO per annum. The Pilot Plant will de-risk the full scale project. As ore processing occurs via a 2 stage process, the construction of the Pilot Plant will include beneficiation & hydrometallurgical process pilot plants. Beneficiation unit operations are proposed to be a crushing circuit, grinding in semi-autogenous grinding (SAG) mill &/or a ball mill, two stage wet high gradient magnetic separation (WHGMS) process, flotation circuit to produce a mineral concentrate, tailings thickening of residues from the WHGMS & flotation circuits co-mingling with the hydrometallurgical tailings for disposal in the tailings storage facility. The hydrometallurgical plant process comprises drying of the mineral concentrate followed by acidification & roasting to crack the mineral structure, water leaching to bring metals into solution, purification & ion exchange to remove impurities, precipitation of RE using oxalic acid & calcinations to convert RE oxalates to oxides, neutralisation & thickening of waste streams prior to co-mingling with the beneficiation tailings & subsequent delivery to the tailings storage facility.
