Dissolution experiments on dolerite quarry fines at low liquid
In this study, the calcium release and reusability of calcium-rich silicate quarry fines, dolerite, were investigated in closed (batch reactor) and open (permeability test) systems at liquid-to-solid (L/S) mass ratios ≤ 15 for MICP applications.

On the potential use of quarry waste material for CO2
01.12.2016The quarry waste was subjected to wet milling in an 80 mL tungsten carbide bowl using ethanol as process control agent (PCA). The ball-to-powder mass ratio was 20:1 w/w, the fluid-to-powder mass ratio 1:2, and the rotation speed 300 rpm. The process was carried out using 30 tungsten carbide balls with a diameter of 10 mm.

Release of Ca and Mg into water occurring during weathering of the rock accompanied by the basic pH of the mineral surface favours capture of inorganic carbon dissolved in water as calcium bicarbonate, and to some extent precipitation of inorganic carbon as the secondary mineral calcium carbonate or calcite.

effectively managing dolerite quarry
Nov 02, 2018 The raw materials from quarry are now routed in plant laboratory where, they are analysed and proper proportioning of limestone and dolerite are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the dolerite. Raw mix is stored in a pre-homogenization pile after grinding raw mix to fine powder.
