The depletion of mining resources forces the industry to process more heterogeneous and complex orebodies. inherent heterogeneity these orebodies their relation processing recoveries have received considerable interest in recent years. properties ores, such as mineral composition association, are known affect flotation performance. Even ores with similar compositions can vary significantly rega...

Abstract The mining industry needs a low-cost and reliable breakage characterization test which can rapidly process large number of samples for geometallurgical modelling. more are tested, the better is understanding ore hardness variability lower design or production risks. proposed solution new testing device, herein named Geopyora, variation roll crusher with an adjustable gap instrumentatio...

Abstract Four different Cu-rich polymetallic concentrates are tested for volatilization of Sb and As during laboratory-scale roasting. The experiments performed between 200 °C 700 °C, at intervals 100 in an inert atmosphere. is much less (maximum approximately 45 pct) than 95 these conditions °C. however limited from the concentrate having mainly a tetrahedrite solid solution ((Cu,Ag,Fe,Zn) 12 ...

The use of geometallurgical modelling is becoming common in the design a concentrator plant and during its operational phase. Predictive aims to define optimized process parameters for accommodate variability ore feed characteristics. main objective this study simulate metallurgical response distinct unit types their blends using kinetic models derived from experimental flotation tests. Kinetic...

Demand for mineral resources is increasing, necessitating exploitation of lower grade and more heterogeneous orebodies. The high variability inherent in such orebodies leads to an increase the cost, complexity environmental footprint associated with mining processing. Enhanced knowledge orebody characteristics thus vital companies optimize profitability. We present a pilot study investigate pre...
