The disclosure relates to a refractory which is resistant to corrosion which degrades the refractory during titanium-ore beneficiation in a furnace, particularly a rotary hearth furnace. In particular, the disclosure relates to a layered refractory lining for a furnace, for use in a titanium ore beneficiation process wherein a titanium oxide-rich molten slag is formed, comprising: (a) a first layer comprising a major proportion of alumina and a minor proportion of zirconia; (b) a second layer comprising a resistant agent for the molten slag; wherein the second layer is between the slag and the first layer.
