SEMIBATCH FLOTATION TESTS - RELIABILITY OF PERFORMANCE INDEXES

This paper describes a method to calculate confidence intervals for cu mulative recovery and grade obtained from semi-batch flotation test re sults. The method is based on the analysis of the propagation of measu rement errors through the calculations. The advantage of using reconci led data from material balancing over raw data is discussed, with refe rence to results of semi-batch rougher flotation tests conducted using a complex Cu-Pb-Zn ore.
