Copper ores compared to the gold ores RY1 and SYW1 which are marginally low indicating uranium is less associated with gold Of the copper rich ore samples uranium levels are high in RGY1 with moderate amounts in RG8 and RR7 RRG4 is the only high grade ore fairly low in uranium similarly with low grade ore SGW1 Figure 3.
These results are compared in Table 12 17 The bulk flowsheet gave superior gold recovery to that of the conventional selective flotation flowsheet The applicability of the bulk flowsheet depends on the amount of pyrite present in the ore In the case of high pyrite coppergold ore the bulk flotation flowsheet does not work as well.
