The amenability of a calcite-bearing ore to the reduction of silica to below 0.2% by physical beneficiation was studied. The objective was to use the ore as a raw material for seawater magnesia production. The ore contains complex gangue minerals such as diopside, forsterite, phlogopite, clinohumite, graphite and quartz. These …

One solution to reduce mine waste is the generation of byproducts or co-products, such as ore-sand, in mineral processing circuits. This approach involves rethinking processes to prevent mine waste production by proactively redirecting silicate-rich (and other) minerals away from waste rock piles or tailings dams.

MICP is a biological process that promotes calcium carbonate (CaCO 3) formation, as a result of biological activity leading to an increase in the saturation state of calcium carbonate (Arias et al., 2017, DeJong et al., 2010, Phillips et al., 2013, Torres-Aravena et al., 2018). Precipitation of calcite can be induced with different purposes.
