  • Publication number: 20130287942
    Abstract: 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.

  • Patent number: 8372179
    Abstract: 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

  • Patent number: 8323801
    Abstract: A process for forming a low emissivity, moisture vapor permeable metallized composite sheet by coating a moisture vapor permeable sheet with at least one metal and exposing the freshly deposited metal to an oxidizing plasma thereby forming a protective synthetic metal oxide over the metal. The composite sheet material is suitable for use as a building construction barrier layer such as roof lining and house wrap.
