![]() ![]() This value was then input into Equation (3) of this manuscript to calculate ANC therm-carb. C neut (wt%) was calculated using the C emission at 800 or 1000 ☌ minus the C emission at 400, 450 or 500 ☌ and the weight of sample prior to decomposition (Equation (2) of this manuscript). C emission (CO 2 and CO) was measured using IR in a N 2 atmosphere. Standard titration-based methods for ANC can be compromised due to contributions from silicate minerals, ion exchange, Fe-rich carbonates, and other transition metal carbonates. ![]() This study developed an industry-applicable, thermal decomposition methodology for quantification of carbonate mineral acid neutralisation capacity (ANC therm-carb) for waste rock, tailings, and other mined materials. ![]()
