This article offers a personal and independent view on the threats to the sustainability of the South African minerals industry. It argues that if the six identified threats of insufficient spending on research and development, general standard of education, nationalization, inadequate infrastructure, Aids prevalence and labour inefficiency are not acted upon as a matter of urgency, the future of the mining industry, along with its important contribution to the economy, is at risk.

The ability to perform three dimensional imaging at micron-scale resolution of real mineral floc sediments and structures using commercially available Micro X-ray Tomography (XMT) instrumentation can be used for the analysis of aggregates and granules, liberation and dewatering of sediments. This paper presents are view of recent work by the authors relevant to the mining and minerals industries. It covers three main topics: X-ray imaging of agglomerates and multi-component mineralic particles,, permeability of sediments, and dissolution of granules with potential application to heap leaching.

Abstract This paper introduces the test results of dark-gray calcium-shale, discusses the infection of strength characteristic and deformation characteristic due to the angle between structural planes. Keywords calcium-shale, failure form, strength, deformation characteristic, structural planes. Zusammenfassung: basier auf der Anwendung von Problematik des Felsenbauprojektes und Beschaffenheit Felsen unter Beaugnshme auf den Zustand des Druckes von einzeler Welle legt dieser Text dar, wie der Winkel der Schichtstrukturflaeche des schwarzgrau kalziumhaltigen Schieferblocks auf die Zerstoerungs-, Intensitaets- und Deformationseigenschaften einwirkt. Schluesselwoerter: schwarzgrau kalziumhaltigen Schiefer, Zerstoerungseigenschften, Intensitaetseigenschften, Deformationseigenschaften, Flaeche dar Schichtstruktur. Résumé – En fonction de la configuration du massif rocheux sous l’état de la contrainte de pression axiale simple et de la pratique de l’ingénierie de roches, le présent article fait la déscription concernant l’influence de l’inclinaison ? de la couche de structure stratifiée du bloc de schiste calcaire gris noir sur ses caractéristiques de destruction, sa spécificité de résistance ainsi que sa nature de déformation. Mot clés – Schiste calcaire gris noir, Caractéristiques de destruction, Spécificité de résistance, Nature de déformation, Couche de structure stratifiée
