Table 13.6 is the mineral liberation data from QEMSCAN. A large quanitity of the<br />

unliberated pentlandyte and chalcopyrite are in a binary structure with non-sulphide<br />

gangue. The liberation of the chalcopyrite and pentlandyte was 34% and 35%<br />

respectively. The BMAL was performed at a grind of 93 µm. Based on this sample,<br />

a finer grind may be required to liberate the valuable minerals.<br />
