Surface mineral extraction :: Banks Group

2021-10-14 · Quarrying or surface mineral extraction is an operation that involves the recovery of shallow mineral deposits from the ground through the removal of overlying rock by excavators and dump trucks. Typically quarries work to depths of 50 to 100m. Sites are carefully designed to ensure maximum mineral recovery with minimum disruption and where ...

Influence of sample surface height for evaluation of peak ...

The axial resolution of confocal microscopy is not only dependent on optical characteristics but also on the utilized peak extraction algorithms. In previous evaluations of peak extraction algorithms, sample surface height is generally assumed to be zero, and only sampling-noise-induced peak extraction uncertainty was analyzed. Here we propose a sample surface-height-dependent (SHD) evaluation ...

Response Surface Methodology

Response surface methodology (RMS) was applied to determine the best conditions for extraction. RMS was performed employing the Statistical Analysis System Version 8.0 software. A complete factorial design (DFC) was used to investigate the effects of two independent variables (irradiation time and ethanol concentration) at three levels (3, 6, and 9 min, X 1) and (0, 25, and 50% v/v, X 2 ...
