Comminution and floatation test work was undertaken to determine the appropriate process flow for the ore to be liberated. The project processing plant is designed to treat 0.4-0.5 Mt/y of high-grade ore. The ROM ore will be two-stage crushed, followed by grinding in a rod mill, with graphite recovered by flotation.Web
