Sampling of run-of-mine mill feed— A practical approach

A sample tree experiment involves splitting at different top sizes, followed by comminution and assaying5. Figure 1 shows the sample tree flowsheet. Two ores were evaluated via this sampling technique. The first sample was a low-grade gold ore (about 5 g/t gold) mill feed sample from a South African gold mine. The particle size was 95% -12 mm.
