This study comprises a comparative review of the effect of ball milling on the CO2 uptake of ultramafic/mafic lithologies, which are the most promising rocks for the mineralization of …
— The failure to further consider and measure the effect of drilling errors can render good face assessment useless, as drilling errors have the same effect as poor burden estimation and add to the danger of boreholes encroaching too close to neighbouring hole positions. The common errors are: 1. Incompatible face/drill. 2. Side …
