Executive Summary
This section of the 2013 Technical Report outlines the proposed processing plant design for the Tulseah Chief Property. The mine is classified as an underground operation, feeding primary crushed ore from a storage silo into a grinding circuit. The plant design includes a SAG mill followed by two stages of ball milling, targeting a cyclone overflow product of P80 45 µm. The ore is characterized as sulphide, containing chalcopyrite, galena, sphalerite, and pyrite, with gold present as free electrum.
The recovery process features a gravity gold circuit using Knelson concentrators to recover electrum, which is then intensively leached to produce doré. The main flotation circuit is sequential, treating copper, lead, zinc, and pyrite in discrete stages. The design incorporates a flotation scale-up factor of 3.0 to ensure effective control of pulling rates. Concentrates are thickened and pressure filtered before storage and transport, with pyrite concentrate designated for mine backfill.
Process control is managed via an on-stream analyzer system within a distributed digital control system, emphasizing the importance of visual line of sight for flotation circuit operators. The report details mineralogy, grinding parameters, flotation reagents, and concentrate handling procedures, providing a comprehensive overview of the metallurgical recovery strategy for the project.
