The tailings are often dumped around the industries concerned where they form ...
BFS is a waste slag from smelting iron in steel plants while FA is a powdery ash collected from boiler flue gas in thermal power plants. The main reaction product of alkali-activated BFS binder mainly involves the dissolution of calcium and the formation of C-(A)-S-H gel (CaO-Al 2 O 3-SiO 2-H 2 O).
Consequently, the surface iron ore mining should consider the selection of the stabilization technique for the waste dump slope as an integral part of the industry (Caldwell and Moss 1981; Chaulya et al. 2000; Khandelwal and Mozumdar 1987). The dump stabilization methods can be classified as: (1) mechanical aspects (rock bolting, netting ...
