This technical report presents the mineral processing and metallurgical testing results and proposed recovery methods for the Eco Ridge Mine Project located in Elliot Lake, Ontario, Canada.
Report context
This technical report was prepared for Pele Mountain Resources Inc. and is dated June 20, 2012. The report addresses the Eco Ridge Mine Project in the Elliot Lake area of Ontario, Canada, and is filed under NI 43-101 standards. The document includes sections on mineral processing and metallurgical testing (Section 13), mineral resource estimation (Section 14), mineral reserve estimation (Section 15), mining methods (Section 16), and recovery methods (Section 17).
Processing route
Mineral Processing and Metallurgical Testing
Section 13 of the technical report documents the mineral processing and metallurgical testing program undertaken for the Eco Ridge project. The testing program was designed to evaluate the processing characteristics of the mineralized material and to develop a suitable flowsheet for uranium recovery.
The metallurgical testing program included ore characterization, comminution testing, and uranium extraction testwork. Samples representative of the proposed mining areas were subjected to laboratory-scale testing to determine grindability, reagent consumption, and leaching performance.
Recovery Methods
Section 17 of the technical report describes the proposed recovery methods for the Eco Ridge Mine Project. The processing route is designed to treat the uranium-bearing ore through conventional milling and hydrometallurgical processing.
The proposed flowsheet includes crushing and grinding circuits to reduce the ore to a suitable particle size for subsequent leaching. Uranium extraction is achieved through acid leaching, followed by solid-liquid separation and uranium recovery through ion exchange or solvent extraction techniques. The final product is expected to be a uranium concentrate (yellowcake) suitable for further refining.
