Residue from the leaching stage was made available to two thickener vendors to conduct CCD thickener settling tests. Additionally, these vendors also conducted primary leach feed slurry thickening tests. These tests provide all the data required for the specification and design of the pre-leach and CCD thickener stages.Web

Based on the current and historical test work, a 27-meter diameter pre-leach thickener will be required for this application. When PGP ores are campaigned, the fine grinding circuit will be bypassed. Estimated gold and silver recoveries used for the design of the processing facilities are shown in Table 4 below.Web
