The objective of the MFT test is to measure the flotation pulp kinetics for all the minerals (ore and gangue) using a standard set of operating conditions. The MFT test provides the industry with a proven solution to the difficult challenge of scaling-up laboratory flotation results to full plant performance. The rigorous scale-up of batch results is achieved by measuring the recovery and kinetics of flotation in the pulp along with the calibration of froth effects in the plant. The MFT test is unique in that it determines the kinetics of mineral separation in the pulp phase exclusively. Froth effects in the plant are later accounted for using Flotation Economic Evaluation Tool (FLEET) modeling. The information obtained from a single MFT test for each mineral in the sample is described by the three MFT test parameters:
The analysis of each MFT test yields the following information:
SGS’s core philosophy is to understand the variability of the ore parameters that affect flotation performance. This arises due to the natural geologic distribution of minerals through a deposit. Once the variability is assessed, we design, optimize or forecast plant performance based on these parameters.
The objective of the MFT test is to have a test program that is simple, standard, quick and can be done at the lowest possible cost. The combination of these benefits means that:
The MFT tests are carried out in two forms: the full MFT test and the mapping MFT test. The only difference between these tests is the number of samples submitted for chemical analysis.
Full MFT tests are conducted to provide sufficient information about the kinetics of the mineral components in the orebody. When this is determined, then numerous mapping MFT tests are conducted, providing many variability data points to the block resource model. The mapping tests are considerably cheaper because fewer samples are submitted for chemical analysis. These savings in assay costs mean that more drill core samples can be tested at the same project cost. The large number of drill core results distributed across the block resource model lead to a robust geometallurgical model and overall better accuracy in both design and production forecasting.
