Abstract: A method of measuring froth stability (as described herein) of a froth in a cell of a flotation circuit for a slurry of a mined mineral containing valuable material and gangue materials is disclosed. The method includes a step of measuring one or more than one froth stability parameter using a measurement column arranged to extend downwardly through the froth in the cell to a location below an interface between the froth and the slurry in the cell. A method of controlling the operation of a flotation cell that is based on the froth stability measurement method is also disclosed.

Abstract: A vessel which produces metal from a metalliferous feed material by a direct smelting process is disclosed. The vessel contains a molten bath having a metal layer (15) and a slag layer (16) on the metal layer and has a gas continuous space (31) above the slag layer. The vessel includes a hearth formed of refractory material having a base (3) and sides (55) in contact with the molten metal and side walls (5) which extend upwardly from the sides (55) of the hearth and are in contact with the slag layer and the gas continuous space. The side walls that contact the gas continuous space include water cooled panels (57) and a layer of slag on the panels. The vessel also includes one or more than one lance/tuyere (13) extending downwardly into the vessel and injecting an oxygen-containing gas into the vessel above the metal layer and a plurality of lances/tuyeres (11) injecting at least part of the metalliferous feed material and a carbonaceous material with a carrier gas into the molten bath so as to penetrate the metal layer.

Abstract: A method and an apparatus for analysing a material, such as coal and iron ore, particularly with a view to identifying contaminants, is disclosed. The method and apparatus are based on the use of multiple (particularly dual) energy x-ray analysis with x-rays at different photon energies. X-rays are transmitted through a material and the detected x-rays are processed to produce an image of the material that combines together the separate images produced by the different photon energy x-rays. The combined image has enhanced contrast which minimises the affects of non-compositional factors that otherwise would affect identifying constituents of the material.

Abstract: The production of highly metallised feed, an intermediate product produced solely by gaseous reductants in two stage reduction processes of that kind, encounters sticking problems, which interfere with continuous processing and productivity. This problem has been overcome by exploiting a high volatile carbonaceous material, such as coal, as the reducing agent for the (partially reduced) oxide ore starting material in the solid state prereduction stage of a duplex process, in which the final stage consists of smelting, to produce the final metal (alloy). Intermediate products of the first stage are char from the coal, which avoids the sticking problem, partially reduced ore and CO and H2, which participate in the prereduction. The process has particular application to iron ores, such as haematite and magnetite and similar derivatives, namely, chromite and oxidic nickel ores. The process may be extended to a triplex, which includes drying, preheating and partial reduction in the first stage, followed by further partial reduction and finally the smelting step. Plant for the process may consist of a shaft furnace or fluidised bed for the prereduction sequence, preferably the latter. For the triplex process, two associated fluidised beds (3, 5) are preferred. Any suitable furnace (7) may be used for smelting, as long as it is equipped for the injection of partially reduced ore, char and fluxes, hot air lancing, off gas and the tapping of molten metal and slag. The final stage of solid state reduction takes place at a temperature of at least 550 DEG C, preferably 750-900 DEG C. At least 50 % of metallisation is essential for satisfactory processing, preferably at least 80 %.

Abstract: A method and an apparatus for producing metals and metal alloys from metal oxides in a metallurgical vessel containing a molten bath having a metal layer and a slag layer is disclosed. The method is characterised by injecting a carrier gas and a solid carbonaceous material and/or metal oxides into the molten bath from a side of the vessel that is in contact with the molten bath or from above the molten bath so that the solids penetrate the molten bath and cause molten metal to be projected into the gas space above the molten bath to form a transition zone. The method is also characterised by injecting an oxygen-containing gas into the gas space to post-combust reaction gases released from the molten bath into the transition zone.
