    摘要： 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.

    摘要： The present invention is one or more processes for producing separable iron and titanium oxides from an ore comprising titanium oxide and iron oxide, comprising: (a) forming agglomerates comprising carbon-based material and the ore, the quantity of carbon of the agglomerates being at least sufficient for forming a ferrous oxide-containing molten slag, at an elevated temperature; (b) introducing the agglomerates onto a bed of carbon-based material in a moving hearth furnace, wherein the carbon-based materials used for both the agglomerates and the bed have a low sulfur content; (c) heating the agglomerates in the moving hearth furnace to a temperature sufficient for liquefying the agglomerates to produce a liquid comprising ferrous oxide-containing slag; (d) metallizing the ferrous oxide of the slag by reaction of the ferrous oxide and the carbon of the carbon bed at a furnace temperature sufficient for maintaining the slag in a liquid state; (e) solidifying the slag after metallization of the ferrous oxide to form a matrix of titanium oxide-rich slag having a plurality of metallic iron granules distributed there through; and (f) separating the metallic iron granules from the slag, the slag comprising greater than 85% titanium dioxide based on the entire weight of the matrix after separation of the metallic iron.
