Sommaire: The Red Dog mine has increased mill
throughput most years since start-up. Although flotation equipment has been added over the last 10 years, the Red Dog metallurgical performance has been restricted by a lack of adequate flotation capacity. Two reduced tonnage trials conducted in 1997 as well as numerous SAG relines have consistently indicated the potential to significantly increase both zinc concentrate recovery and grade with additional flotation capacity. Later in 1999, a new circuit was...

Sommaire: A cornerstone of any successful mining
project is an understanding of the mineral
assemblage and metal distribution comprising the deposit. Knowledge of the precise mineral/metal zoning enables an operation to utilize different mining and processing methods optimized for different parts of the deposit. The Lac des Iles mine, located in northwestern Ontario, is one operation that depends on a good understanding of these issues. Current
resources for the Roby Zone total 94.1 Mt
grading 1.66 g/t...

Sommaire: Geological and technical problems are
often considered the most important ones
affecting new mining projects. Typical problems and likely causes are reviewed based on current Quality Management and Continuous Improvement (QMCI) perspectives, giving particular attention to the work of W.E. Deming. As the “system approach” is an essential part of these policies, its characteristics are described with particular attention given to cultural-
behavioural, organizational and systembased
constraints...
