Executive Summary
This 2022 Feasibility Study by SRK Consulting outlines the processing plant design for the Madaouela Uranium Project in Niger. The project focuses on the Miriam open pit ore body, with provisions for future underground ore treatment. The flowsheet utilizes a traditional approach combined with novel dry milling and ion exchange technologies to recover uranium and molybdenum. The plant is designed for a throughput of 1,000,000 tonnes per annum with a mine life of 15 years.
The processing circuit begins with primary crushing and dry milling using VeRo Liberator units, followed by two-stage acid tank leaching. Uranium recovery is achieved through solvent extraction (SX) and precipitation of Ammonium Diuranate (ADU), while molybdenum is recovered via continuous ion exchange (CIX). The study includes a Class 2 capital cost estimate of approximately $245 million USD, with operating costs estimated at $32.4 million annually.
Processing Profile
- Crushing: Primary Jaw Crusher
- Milling: VeRo Liberator (Dry Milling)
- Leaching: Two-stage Tank Leaching (Sulfuric Acid)
- Molybdenum Recovery: Continuous Ion Exchange (CIX)
- Uranium Recovery: Solvent Extraction (SX) + ADU Precipitation
- Future Additions: Flotation (for underground ore)
