Combined with numerical simulation, the influence of confining stress on cutting process, fracture conditions and cutting efficiencies of soft and hard rock has
The class of bi-directional optimal velocity models can describe the bi-directional looking effect that usually exists in the reality and is even enhanced with
Cemented tailings backfill(CTB) is made by mixing cement, tailings and water together, thus cement hydration and water seepage flow are the two crucial factors
Simulated heap bioleaching of low-grade high pyrite-bearing chalcocite ore was conducted at 40 °C with aeration of CO2 and N2.Ore samples were collected at
The microstructure and properties of a quarternary Mg-8Er-5Zn-0.5Zr(mass fraction, %) alloy with the low Er/Zn mass ratio of 1.60 were investigated. It is found
