Eroding Confidence in Gully Location Risk Prediction in Mine Pit Rehabilitation
Land Degradation &Development, EarlyView.ABSTRACT Understanding how rehabilitation measures, such as landform shaping, and surface finishes impact gully erosion risk could assist in designing less erosive rehabilitation. In this study we use high resolution digital elevation models of rehabilitated mine pits to explore risk factors for gully formation.

Potential of Saudi Arabian bauxite to produce low-carbon cement
CementTo produce calcium aluminate cement (CAC), bauxites are usually fused with lime/limestone at high temperature (1600 °C). At this temperature, the bauxite´s hydrates of alumina break down - dehydroxylation - and combine with calcium forming monocalcium ...
