Abstract: The invention provides a mining tool (30) for mining an underground substantially horizontal seam of material comprising an eductor module (60) and a fluidising module (62). The fluidising module (62) includes a plenum (66) adapted to receive high pressure fluid from a mining string, and one or more fluid jet nozzles (42,43.44) for emitting the high pressure fluid to mobilise material of the seam. The eductor module (60) includes an eductor assembly (69) adapted to recover the mined material to return it as a slurry along the string. In use, the tool is connected to a mining pipe or string (35) extending from the surface to supplying said high pressure fluid to the eductor arrangement and fluidising nozzles. The eductor assembly is positioned toward the proximal side of the tool which is connected to mining pipe (35). The fluidising jet nozzles are positioned more towards the distal end of the tool, such that when in use, eductor recovers the slurry at said proximal position relative to the string. While the mining tool is continuously withdrawn towards the ground surface along the substantially horizontal borehole, high pressure fluid is fed to the tool to fluidise the material in the seam via the fluidising jet nozzles (42,43,44), and recover the material as a slurry via the eductor arrangement positioned “upstream” from the jet nozzles.

Abstract: A foundry sand comprises a blend that includes a silica sand and a zircon aggregate. The zircon aggregate exhibiting a sharp rise in linear thermal expansion coefficient in a temperature band above 1200° C. A method of casting an article in molten metal at a temperature above 1200° C. includes forming a single or multi-part mold for the article from the above-described foundry sand, admitting molten metal to the mold at a temperature such that at least one or more regions of the foundry sand in contact with the admitted metal are heated to a temperature within the temperature band, and cooling the mold and metal to obtain a cast article.

Abstract: This invention relates broadly to the production of titanium alloys by electrolytic reduction processes, and is concerned in one or more aspects with the preparation of a feedstock for such processes. In other aspects, the invention relates to a novel synthetic rutile (SR) product and to methods of producing titanium alloy from titaniferous material.

Abstract: A process for improving the grade and optical quality of zircon, comprising: baking a mixture of a zircon feed and concentrated sulphuric acid at a baking temperature in the range of from 200 up to 400° C., and for a time to form water leachable sulphates with impurities therein including at least iron and titanium; leaching the baked mixture to dissolve the leachable sulphates; and separating the zircon from the leachate containing the leached sulphates, which separated zircon is thereby of improved grade and optical quality.
