| Company | Coeur Mining |
| Date | 2015-11-02 |
Executive Summary
The Palmarejo Complex, located in Chihuahua State, Mexico, is a significant mining operation utilizing both underground and open pit mining methods. The processing facility is designed for a throughput of 6,000 tonnes per day, employing a complex flowsheet to maximize recovery of gold and silver. The plant integrates crushing, grinding, flotation, and intensive leaching of concentrates.
Key processing milestones include the transition away from Carbon-in-Leach (CIL) to an agitated cyanidation circuit for flotation tailings, completed in 2014, and the expansion of the Merrill Crowe circuit to improve precious metal recovery from pregnant solutions. The operation achieves an overall recovery of approximately 94.0% for gold and 91.0% for silver as doré.
