Sommaire: This paper reviews the types of selective continuous miners (SCMs) available at present, and compares their main features. Furthermore, operating practices and mine planning aspects of the SCMs applications are reviewed and conditions for efficient application of this equipment are defined. Finally, the potential applications of the SCMs in surface mining of oil sands are discussed.

Sommaire: The Nova Scotia Department of Mines and Energy located a drillhole at Riverside Corner, Hants County, Nova Scotia, to examine the stratigraphy, structure and potash potential of the Kennetcook River gravity low. This evaporite-related gravity anomaly is one of the largest virtually unexplored gravity anomalies in Nova Scotia. The drillhole intersected a structurally complex sequence of lower Windsor Group ('B' Subzone) evaporites. Downhole geophysical wireline logs were used, in conjunction...

Sommaire: A detailed study of the compositional relationships of the U-and Th-bearing minerals in Elliot Lake uranium ores has been conducted, particularly with regard to uranothorite, which clearly plays a critical role in hydrometallurgical processing. Application of the rotating disc progressive-leaching technique to individual mineral grains and intergrowths of known compositions has defined for the first time the solubilization behaviour of the minerals in question.
