Table 7 shows the enrichment and yield calculations for
the frother type experiments at 50 g/t. Results for terpineol
showed a yield of 34.06%, Te enrichment of 1.5, Au enrich-
ment of 0.8, and Ag enrichment of 1.31. OREPREP X-237
yielded 58.09%, Te enrichment of 1.5, Au enrichment of
0.68, and Ag enrichment of 1.60. Therefore, the results
suggest that the most effective collector and frother com-
bination to address the loss of Te Au-Ag to CT is 150 g/t
AERO 8989 with 50 g/t MIBC.
