Refractory-grade magnesia in Canada: M34-20/163E-PDF

“The increasing demand for magnesia refractories is a direct result of the increasing use of the basic oxygen furnace in the steel industry. This trend may be expected to continue, at least until the open-hearth furnace has been phased out. At the same time, the specifications for refractory-grade magnesia are becoming more rigid, particularly with respect to iron oxide and to boron, which is present in seawater magnesia. As a result, more interest is being shown in the beneficiation of natural magnesitic ores to produce high-purity magnesia free from boron and very low in iron oxide. This bulletin discusses the properties of refractory grade magnesia, reviews the magnesia industry in Canada both past and present, and lists known Canadian sources of magnesitic rock"--Abstract, p. i.
