The Sherritt-Cominco Copper Process PART III: Commercial Implications

Abstract The operation of the pilot plant for the S-C Copper Process during 1976 has provided the basic data for the design of a commercial-scale plant. This paper introduces the commercial aspects of the S-C Copper Process through the presentation of a process flow diagram, a schematic flow diagram and basic design parameters for 75,000 tonnes per year (tpy) copper rod production from chalcopyrite concentrate. Basic operating requirements are outlined and a preliminary estimate of operating and capital costs for a Western Canadian location are summarized. The results have been compared with a modern smelter/electrorefinery to highlight the advantages and disadvantages of these two alternatives and to show why the new S-C Copper Process technology should be of interest to the copper industry.
Keywords: S-C Process, Copper recovery, Energy requirements, Metallurgical costs, Hydrometallurgy.

Summary: Current treatment and disposal procedures are compared for clay slimes resulting from the extraction of Alberta oil sands, the extraction of Florida phosphate matrix, the recovery of diamonds from kimberlite deposits in South Africa, the recovery of kaolin from clay deposits in southwest England and the upgrading of bauxite ore. Published research in the area is reviewed, and common trends which are emerging in the disposal of clay slimes are discussed.

Summary: Recently, there has been much debate as to the relevance of reporting financial results using the conventional accounting systems, which is based on historical costs, during a period of rapid inflation. In the following paragraphs, the symptoms, if not the causes, of inflation, its detrimental effect on the financial soundness of business in general and the financial reporting changes being advocated to overcome perceived weaknesses in the present financial reporting system in accounting for...

Summary: From the characteristics of the new (1976) electronic components and units that are being marketed, the author has tried to foresee the types and the performances of the near-future slope-monitoring equipment. Much-improved sensors, instruments and systems for pit use can now be developed — sun-powered telemetry remote stations are feasible, very sensitive as well as precise and drift-free liquid level inclinometers will be available, new techniques for distance measurement with lasers...

Summary: Sherritt Gordon and Cominco, with financial assistance from the Canadian Government through PAIT, have developed a hydrometallurgical process for refining copper from sulphide concentrates. The main objective of the project was to develop a process applicable to a wide range of concentrates with respect to copper content, other metals content and impurities, within the economic parameters set by present smelting and refining practice. Other important objectives were to recover sulphur in its...

Summary: High-grade gold-silver mineralization associated with electric and argentite was discovered in a quartz vein at the Chappelle property, 273 km north of Smithers, B.C., in 1969 following a regional geochemical reconnaissance program in the Cassiar-Omineca Mountains. Subsequent exploration resulted in the discovery of numerous quartz veins with associated precious-metal values in a belt 17 by 3 km in area centrally located within Toodoggone Group volcanic and sedimentary rocks of Lower to...

Summary: The present method of shipping potash to the myriad of consumers is inefficient, not only because of the extreme and unpredictable nature of seasonal demand, but also because railway car turnaround times are very lengthy.
The Floating Train system employs unit trains of potash operating from Saskatchewan mines to distribution warehouses located throughout the six corn-belt states of Minnesota, Iowa, Wisconsin, Illinois, Indiana and Ohio, transshipment points at Thunder Bay and the U.S....

Summary: An integrated pilot plant for the development of the S-C Copper Process was constructed at Fort Saskatchewan in 1975 and operated in 1976. The pilot plant was designed to treat 9 tonnes per day of a pyritic copper concentrate. A demonstration run conducted during the last quarter of 1976 averaged 90% on-stream time, and confirmed that the process is operable as a stable and integrated unit. The paper describes the parameters and equipment developed for thermal activation of chalcopyrite...

Summary: Remote and isolated, located in a frigid, hostile environment, the Black Angel mine in Greenland had to create a warm social environment which would help attract and retain a stable work force of miners and support staff. The high cost of personnel turnover plagues many mines and, when the mine is inside the Arctic Circle, accessible by helicopters which are highly vulnerable to unpredictable weather conditions during the long, dark winters, the potential costs of personnel turnover become...
