摘要： A process for recovering valuable metals from laterite ores and concentrates that are contaminated with iron is disclosed. The process includes reducing ferric ions to ferrous ions in a leach liquor containing a valuable metal and iron in solution using a reductant, neutralising the liquor to reduce the free acid concentration in solution to levels suitable for nickel precipitation; and precipitating the valuable metal using the reductant and seed particles under process conditions, including one or more of seed particle size, seed composition, and temperature, that are selected to maximise nickel precipitation and to minimise iron precipitation.

摘要： A continuous flotation process and apparatus for iron-containing sulphides in ores and concentrates of ores are disclosed. The process includes adjusting the pH of an aqueous pulp of the ores or concentrates of the ores to be in the range of 6.5-8.5 and thereafter adding a reducing agent to modify an iron hydroxide film on the surface of iron-containing sulphides in the ores or ore concentrates to enable adsorption of a collector onto iron-containing sulphides. The process also includes adding the collector to the pulp prior to, during, or after adding the reducing agent. The process also includes aerating the pulp to increase the pulp potential to a level sufficient to allow collector adsorption onto the iron-containing sulphides and thereafter bubbling gas through the pulp and subjecting the aqueous pulp to froth flotation to produce a froth containing said sulphide containing minerals.

摘要： The present invention provides a two-step dust leaching process. The first step includes a first leach followed by solid/liquid separation. The "liquid" phase from the solid/liquid separation has a relatively high concentration of a valuable metal (such as copper) and a relatively low concentration of polonium mostly. The "solid" phase from the solid/liquid separation contains valuable metals (such as copper, gold and silver) and polonium and has a relatively high concentration of polonium compared to the liquid phase. The "solid" phase is transferred to the second step. The second step includes a second leach followed by a solid/liquid separation. The "liquid" phase has a relatively high concentration of polonium and a low concentration of valuable metal (such as copper). The "solid" phase contains valuable metals (such as copper, gold and silver) and polonium and has a relatively low concentration of polonium. The liquid phase from the first step and the solid and liquid phases from the second step can be used beneficially in other processing steps in a refining plant for recovering the valuable metals.

摘要： The present invention relates generally to a process for flotation of sulphide minerals where a flotation pulp is separated into a coarse stream and a fine stream, preferably containing particles coarser than about 30 micron and particles finer than about 30 micron, respectively. Typically, alkali and depressant are added to the coarse flotation stream only and acid and activator are added to the fine flotation stream only. During flotation of the fine stream, acid and/or activator may be added at the conditioning, cleaning, re-cleaning, cleaner-scavenging or third cleaning stage. During flotation of the coarse stream, alkali and/or depressant may be added at the conditioning or cleaning stage.

摘要： Traditionally, processes to produce ferronickel, nickel iron and stainless steel are excessively multistepped, energy consuming, have refining difficulties and result in the formation of a slag, which cannot be usefully exploited as an aggregate in road material or in concrete. All of these drawbacks contribute to high manufacturing costs. These disadvantages can be overcome by using a direct smelting procedure, followed by a refining step. The source material consists of a nickel bearing ore and/or concentrate, together with an iron source as make up material, which is charged into a bath smelter (50) operating in a reduction/oxidising mode, continuously or intermittently. A reducing slag (57) containing carbonaceous material is formed over molten metal alloy (55), and oxygen (60, 61) is blown through tuyeres (58, 59) into the carbonaceous slag (57) to produce reducing gas and the space above the slag (57) to oxidise any excess carbon monoxide, so that a quiescent slag layer (56) exists between the turbulent slag layer (57) and the molten metal layer (55). Reduction to metal droplets occurs in the upper slag layer (57) and these percolate down through quiescent slag layer (56) to metal layer (55), both of which are siphoned or tapped off, as they fill to capacity. Mineral feed may consist of dried and/or calcined ores and/or concentrates of nickel sulphide and/or nickel laterite with/without iron ore and optionally chromite as a source of chromium. Fluxes such as calcium oxide are added to maintain a basic slag, which is kept fluid at the elevated temperature range of 1700 DEG C to 2000 DEG C. The second refining and finishing step is carried out in an argon oxygen decarburiser and/or a converter.

摘要： The present invention relates to a gravity/flotation circuit where a mineral stream, such as a flotation rougher or cleaner concentrate, undergoes a two stage size separation wherein: i) the screen of the first stage provides a coarse stream of particles greater than 110 microns and a fines stream of particles less than 110 microns; and ii) the fines stream of less than 110 microns is subjected to the second stage separation whereupon a cyclone provides an ultrafine/slimes stream of p80 less than about 25 microns and a middlings stream of p80 greater than around 25 microns. The middlings stream is subjected to flotation to recover nickel sulphide which is sent to final concentrate, and reject or depress magnesia which undergoes gravity separation to concentrate the MgO. It has been discovered that a large proportion of the MgO minerals in the concentrate are contained in the 30 to 100 micron size fraction and that they are well liberated making physical separation possible. Furthermore, the nickel sulphide minerals and magnesia minerals have a significantly different specific gravity which can be exploited using gravity separation equipment to achieve magnesia rejection.
