Terrace Mining Operations in Stratified Deposits
By A C. Carter
The increasing need for alternative energy sources as well as the less clearly perceived but equally increasing demand for non-fuel minerals has resulted in extensive exploitation of near surface depo

The Reduction of Nickeliferous Laterites: Thermodynamic Considerations
By Turnbull A. G
Thermodynamic calculations based on the ideal system NiO - Fe203 - H2(g) - CO(g) - H2O(g) - CO2(g) show that it is not possible to selectively reduce nickel oxide in the presence of hematite because f
