Feasibility of iron recovery from Mount Wright tailing material

Abstract Oleic acid flotation of Mount Wright thickener underflow tailing material has been shown to be capable of increasing plant recovery by 3%. High levels of oleic acid addition (1.5 kg/t) are required, which limit the economic practicality of the system at this time. Nevertheless, from a technical viewpoint, the process is stable with respect to extreme fluctuations in oleic acid requirements, pulp pH and pulp temperature. Methods to reduce the average consumption of oleic acid need to be found. One technique that merits further testwork uses the "piggy-back" principle to float hematite fines with coarsegrained hematite particles.

Summary: The paper discusses coal research in relation to the special needs of Western Canada, with its large resources of lignite and subbituminous coals. Research programs are presented under the following headings: Coal Liquefaction, Pyrolysis, Fluidized-Bed Technology, Underground Coal Gasification and Supporting Investigations. Typical processes are presented and their relevance to Canadian coals is described. The long-term plan of the Alberta Research Council for coal research and the steps...

Summary: Research and development on the production of liquid fuels from coal is rapidly expanding worldwide. Almost every industrialized country is engaged in coal liquefaction research and process development. In Canada, the federal government, through CANMET, is actively supporting coal liquefaction research and development in a number of areas.A review of the basic principles and some of the processes in the production of liquid fuels from coal is presented with reference to the characteristics of...

Summary: This paper traces the introduction and use of fire-resistant (FR) fluids in hydraulic systems at underground mines in British Columbia. Reasons are given for the decision to make compulsory the use of such fluids in underground mines after January 1, 1975 by provincial government legislation. Examples are quoted of fires caused, or supported by, mineral oils which have resulted in loss of life and property.The basic principles of hydraulic systems are reviewed in order to present the effects...

Summary: Texasgulf's 25-foot-diameter Kidd Creek No. 2 Shaft is situated next to the company's No. 1 Shaft, so that both shafts can share common surface and underground facilities. Shaft construction, covering a span of five years from collaring to commissioning, started by freezing the 50 feet of grey varved clay covering the bedrock. After first completing the concrete headframe, sinking to the 5100-foot horizon utilized two different shaft construction methods. The top 2800 feet was excavated by...

Summary: The Strathcona Mine is located in Levack Township on the North Range of the Sudbury Basin. The main orebody consists of pyrrhotite-pentlandite-chalcopyrite mineralization associated with an embayment of the footwall of the Sudbury Irruptive. A zone of massive chalcopyrite-cubanite-pentlandite mineralization occurs in a complex vein system in a series of mixed gneisses and breccias in the footwall. Vein widths vary from a few millimetres to 6 metres. In December 1979, this zone was estimated...

Summary: There has been considerable output over the last three decades from the social sciences concerning man and his working environment. In the mining industry at large, however, authoritarian, hierarchical control systems remain the norm, and it can be argued that something less than optimum effectiveness in terms of both productivity and worker satisfaction has resulted.Recently (1975), Campbell Chibougamau Mines Ltd. devised a most interesting organization and incentive system that links the...
