An undergraduate pilot plant experience

Abstract Pilot Plant Operations is a final-year core course given to the Metallurgy and Materials Science students at the University of Toronto. This course involves a laboratory study of an industrial project at an industrial site. Details of this program are discussed and reviewed after eight years of experience.
Keywords: Pilot plants, Metallurgy, Materials science, Education, Stelco, Arc spray process, Zinc coatings.

Summary: The authors make recommendations that they believe will improve the efficiency of a mining company's use of a mining contractor's services. The recommendations are in the form of specific "DO" or "DO NOT" instructions, giving explanations and covering the contracting process from the end of the feasibility study to the end of the job.

Summary: Hydraulic mining consists of coal erosion by powerful jets of water from hydraulic monitors operated by remote control. The broken coal is crushed and mixed with water and then transported from the face to the surface using gravity whenever possible. This is a simple, safe and productive method. It will easily satisfy North American productivity standards if the structural features and coal properties are favourable for water jet cutting technology (Kaiser Resources Ltd., hydraulic mine).

Summary: This paper describes the development of a dynamic model for a full-scale (64 tonnes/hr) grinding circuit consisting of an open-circuit rod mill feeding a ball mill operating in closed circuit. The object of constructing such a model is to investigate the static and dynamic behaviour of potential control schemes. Model selection, data processing and parameter estimation are discussed, and static and dynamic results of simulations are presented. Conclusions are drawn with regard to the adequacy...

Summary: The Kemess porphyry copper-molybdenum deposit occurs in the Intermontane Belt of north-central British Columbia. The deposit is in andesitic to basaltic flows and tuffs which may be correlated with the Savage Mountain Formation of the Upper Triassic Takla Group. Most known chalcopyrite and molybdenite is associated closely with a 500-m-diameter zone of intense quartz-sericite-pyrite alteration. A zone of supergene enrichment, up to 30 m thick, underlies a leached capping about 20 m thick. The...

Summary: On the north shore of the St. Lawrence River, in Quebec, are located orebodies of low-grade titaniferous magnetite.   The Quebec Mining Exploration Company (SOQUEM), who have an interest in the deposits, believed that beneflciation of the could generate sufficient revenue to defray the mining costs and the costs of transporting the ore to a steel production facility. A joint research project of SOQUEM and CANMET investigated alkaline roasting of a magnetic concentrate, followed by...

Summary: Tungsten skarn deposits on the Clea property in the Selwyn Mountains, Y. T., are related genetically to a quartz monzonite stock, about 500 metres in diameter at the surface. Lower Paleozoic sedimentary rocks are metamorphosed for a distance of 3 km from the stock. Tungsten-bearing skarn mineralization within the altered sedimentary rocks is of two types: sulphide-rich pods and calc-silicate beds. The most significant scheelite concentration is in calc-silicate beds near or adjacent to the...

Summary: World metallurgical coal imports totalled 110 million tonnes in 1978. Of this amount, Japan imported 50 million tonnes, making it by far the largest and most important coking coal market. British Columbia and Alberta exported 12.0 million tonnes of coking coal in 1978, or 11% of the world total. Virtually all of these exports were directed to Japan, making up 22% of total imports.Some observers have suggested that because Japan is almost the exclusive buyer of British Columbia and Alberta...
