Executive Summary
This technical report outlines the recovery methods for the Monterde Project, based on metallurgical testwork and engineering design appropriate for a preliminary economic assessment. The proposed processing plant is designed to treat 2,800 tonnes per day of ore, utilizing a conventional gold and silver recovery circuit. The design focuses on maximizing metal recovery while minimizing capital and operating costs through the use of agitated tank cyanide leaching, counter current decantation, and a Merrill Crowe finishing step.
The comminution circuit involves a jaw crusher followed by semi-autogenous grinding (SAG) with a pebble cone crusher. A gravity circuit is integrated to recover coarse gold and silver, bleeding 25% of the grinding load to a shaking table cleaning operation. The leaching process utilizes slaked lime and cyanide solution in agitated tanks with a 48-hour retention time, followed by washing in CCD thickeners.
Final metal recovery is estimated at 95.6% for gold and 61.8% for silver from mill feed. The precipitate from the Merrill Crowe circuit, along with gravity concentrates, is refined in a propane-fired plant to produce gold/silver doré bars. Tailings are treated for cyanide destruction before disposal in a tailings storage facility, with water reclaimed for reuse in the process plant.
