Sommaire: In this paper the author presents the results of the 1992 CIM survey of graduates in minerals and technology programs in Canadian post-secondary institutions. As usual, the trends are out-of-phase with the economic state of the industry. People who chose a minerals career in the prosperous days of the late 1980s are now entering a labour market in recession.
The cyclical nature of enrollments is illustrated in a series of figures showing the trends since the CIM survey was begun in 1956 (and...

Sommaire: In previous publications by the author, significant advances and generalizations of the theory of sampling of broken ores, prompted and confirmed by experimental results, have been presented. This paper shows how to implement these theoretical results in practice. The models to be used are reviewed, with a description of the various sampling parameters involved. Then the methodology for the experimental assessment of those parameters, including segregation factors, is described in simple and...

Sommaire: Rio Algom's Stanleigh Mine and Mill Operation was officially started up in August 1983. In September 1982, Rio Algom contracted Estonix International Inc., from Lively, Ontario, to develop and implement two innovative programs: (1) Work Renovation Planning, and (2) Systems Performance Training. This paper deals with the development and implementation of these two concepts relative to the plants technology from start-up to present and the exceptional results achieved. This paper discusses how...

Sommaire: This paper tells the story of how the Dome Mine in South Porcupine increased its maintenance effectiveness and reduced its maintenance costs in two phases. In the first phase, a maintenance audit was conducted, and the results led to some changes that improved maintenance, especially in the underground equipment area. The audit methods, and the changes made will be reviewed. In the second phase, management made changes in the maintenance organization and methods, following a prolonged strike...

Sommaire: Water is encountered at the majority of underground mines, both over their lifetime and during each stage of development and production. The dewatering system is one of the most important and costly components of an underground mining operation and it is often not well designed and analyzed. An effective design of a mine dewatering system will greatly reduce its energy cost as well as improve working conditions and reduce production costs. A computer-based system, called Qpump, has been...

Sommaire: Performance testing ofprepartion plants is referred to as plant audit. It evaluates plant performance under normal operating conditions and is aimed at improving yield through knowledge of actual process performance and interactions between different processes in a plant.
This paper describes the program to evaluate the performance of several Canadian preparation plants. The performance test requires the planning of a sampling campaign that would include all circuits in the plant. Samples are...

Sommaire: During the summer of 1989, Les Mines Selbaie, with the cooperation of University Laval initiated a research project to evaluate the column flotation technology for its concentrator near Joutel, Quebec. The experimental work involved both a 5 cm by 11 m laboratory column and a 45 cm by 10 m home-made pilot unit.
Amenability tests were conducted using both units on various streams of the plant. Results showed that columns are not suitable for the copper cleaning circuit because the loss of...
