The Kilmar Magnesite Mine and Heavy Media Separation Plant

Canadian Refractories, Limited, produce a wide range of basic refractories. The chief raw material used in their manufacture is the magnesite which Is mimed, and beneficiated in a heavy media separation plant! at Kilmar, Que. This paper describes the underground operation and the plant and explains how the gravity separation of light, siliceous gangue from the ore has changed the mining practice, increased the ore reserves, and improved the chemical uniformity of the crushed ore.
