Sommaire: This report presents the results of a laboratory study undertaken to evaluate ground granulated blast-furnace slag from Algoma Steel Corporation, as a replacement for Portland cement in cemented mine backfill. The evaluation was based on the results of compressive strength tests performed on cylinders cast from mixtures made with a granulated blast-furnace slag and tailings from four different mines in the Sudbury basin. Various percentages of slags and various binder to tailings ratios were...

Sommaire: Many plants use computers for process control, and most have computerized Management Information Systems, but few have been able to have these systems interact with one another. Developing this system interaction is not a one-step process but requires careful planning and implementation. This paper describes two projects that were implemented to provide the bridge between the process control and management information systems of Cominco Limited. Both projects include the replacement of...

Sommaire: The Red Dog deposit of the western Brooks Range, Alaska was discovered in the 1970s. Two mineralized areas are present, the Main and Hilltop deposits. With indicated and inferred reserves of 77 million tonnes of 17.1 % zinc, 5.0% lead and 82 g/tonne silver, the Main deposit of Red Dog represents one of the world's largest zinc-lead deposits. Since serious evaluation by Cominco commenced in 1980, a better understanding of deposit geology has been gained through 10 715 m of diamond drilling and...

Sommaire: The Agnew (also known as the Perseverance) nickel deposit and its northern extension, the Rocky's Reward deposit, form one of the world's largest accumulations of nickel sulphides hosted by komatiites. Agnew was previously classified as an "intrusive dunite-associated" deposit. It has now been shown that the sulphides are hosted by komatiite flows which underlie an adcumulate-textured dunite body that crystallized in a large lava channel.
The rocks of the mine area have been...
