1. Cleaner pump has two slurry streams discharge. Cleaner 1 stream has a flowrate of 5.0 m3/h and contains 52% solids. Cleaner 2 stream has a flowrate of 3.3 m3/h and contains 55% solids. Density of solids is 3000 kg/m3. a. Calculate the tonnage of dry solids pumped per hour (t/h) per stream. b. Weighted average of Cu and Au of Cleaner Assay given that Cleaner 1 has an assay grade of 23.65% Cu, 45.2 g/t Au. Cleaner 2 has an assay grade of 25.83% and 42.8 g/t Au.
