Sampling and flotation testing of Sudbury Basin drill core for process mineralogy modelling

The PGM flotation predictor: Predicting PGM ore flotation performance using results from automated mineralogy systems

“…Similar approaches to predicting floatability and recovery of ores using mineral particle properties determined by automated SEM systems have been documented (Evans et al, 2011;Evans, 2010;Ford et al, 2007;Hunt et al, 2008;Lotter et al, 2003;Wightman et al, 2010Wightman et al, , 2008. These, however, apply largely to base metal sulphide recovery, and do not involve the development of custom designed software to interrogate the mineralogical data.…”

The effect of frother type and dosage on flotation performance in the presence of high depressant concentrations

“…The volume of froth obtained in these tests, as indicated by the water recovery, was substantially greater than that obtained from tests conducted in the presence of solids. This is as a result of the destabilising effects of the solids even in the absence of a depressant where the maximum amount of froth stabilising NFG was present or possibly the adsorption of frother onto the solids (Lotter et al, 2003).…”

“…This suggests that there may have been some interaction of DOW 250 with NFG in that the increase in frother chain-length has led to an adsorption of the frother onto NFG which may have resulted in some NFG depression. In testwork conducted by Lotter et al (2003) it was shown using ToF-SIMS (time of flight secondary ion mass spectrometry) that DOW 250 had an affinity for Mg silicates in that these particles were covered by a surface layer of DOW 250. Surrounding sulphide mineral particles were unaffected.…”

Nanoscale Automated Quantitative Mineralogy: A 200-nm Quantitative Mineralogy Assessment of Fault Gouge Using Mineralogic

“…The key application area of this technique was to provide an automated and routine analysis capability to quantify the mineralogy and textures of ore mineralogy (modal mineralogy, liberation, association, etc.) to aid mineral processing plant development, optimization, and troubleshooting [1,3].…”
