Executive Summary
The Cerro Blanco Gold Project Technical Report outlines the process plant design for treating gold- and silver-bearing ore to produce doré. The flowsheet is based on metallurgical testwork and conventional unit operations, targeting a nominal throughput of 4.0 million tonnes per year. The design includes comminution, cyanide leaching, carbon adsorption via carbon-in-pulp (CIP), elution, and gold recovery circuits, with tailings treated in a cyanide destruction circuit.
Key operational criteria include a crushing plant availability of 75% and grinding/leach availability of 92%. The process utilizes a C160 Jaw Crusher, a SAG and ball mill grinding circuit, and a 36-hour leach residence time. The plant is designed to achieve 93% overall gold recovery and 84.3% silver recovery, with tailings filtered to a moisture content of 16-18% for dry stack storage.
