摘要： A process for recovery of precious metals from ores or concentrates containing refractory carbonaceous material by cyanidation leaching. The process involves addition to the ores or concentrates at least one cationic surfactant before or during the addition of cyanide-containing solution. The agent enables the recovery of precious metals by cyanidation from high preg- robbing carbonaceous ores and improves the recovery of precious metals by cyanidation from medium to low preg-robbing carbonaceous ores. The agent also prevents froth and foaming formation during the cyanidation process.

摘要： The invention relates to a method for processing pyritic copper sulphide concentrate, in which, in addition to copper, there is arsenic and gold bound to the sulphide minerals, or invisible gold. In the method concentrate is leached into a chloride-containing solution. Raw material leaching is performed in conditions where the copper, iron and arsenic of the raw material dissolve, but the gold-containing material remains undissolved. The chloride solution obtained is routed to neutralisation, where the iron and arsenic in it are precipitated. The purified copper solution is routed to liquid- liquid extraction, in the stripping stage of which copper is transferred to a sulphate solution, which is routed to copper electrowinning. Gold is recovered from the leaching residue by some known method.

摘要： This invention relates to a method of removing cyanide in the form of free cyanide (cyanide ions i.e. CN") and weak acid dissociable cyanide (WAD) from an aqueous stream. WAD is cyanide complexed with metals such as Cu. The method finds particular application in removing cyanide from a tail stream from a carbon in leach (CIL) mining operation. The method of the invention is carried out by contacting an aqueous stream containing cyanide with carbon, under conditions wherein the Eh (oxygen reduction potential (ORP) measured in mV) of the aqueous stream is O or above. Advantageously the pH of the solution is buffered to from 7 - 9.

摘要： A trench leaching system (10, 10') including a tank (14) containing a charge of ore (50) flooded with a liquid solvent (94) up to the level of a gutter (90). A pump (42) recirculates the liquid solvent (94) upwardly through the charge of ore (50) via a sparging array (80) for dissolving valuable minerals which are reclaimed through a series of cyclones (44 and 46) and stripped out of the pregnant solvent by a carbon column (100). The rate and pressure of the liquid solvent (94) flowing through the sparging array (80) upwardly though the charge of ore (50) are kept below the amount that would fluidise the charge of ore (50) and at an amount that produces channels (114, 122) which follow random paths that vary with time through the charge of ore (50), wherein particles of ore in the channels (114, 122) are agitated by the liquid solvent (94) and wherein particles of ore outside the channels (114, 122) are maintained substantially static and in contact with the liquid solvent (94). Such a system (10, 10') can process low grade ore (50) at low operating and capital costs.

摘要： A method for the recovery of metal values from a metal value-bearing material containing arsenic and/or antimony and a source of sulphate ions such as sulphide ore or concentrate is disclosed. In one form the method comprises the steps of: (a) providing a feed stream comprising a metal value-bearing material containing arsenic and/or antimony and a source of sulphate ions; (b) subjecting the feed stream to oxidative conditions under elevated temperature and pressure conditions in the presence of at least one component selected to decrease the effective concentration of free acid generated during the pressure oxidation step and promote the formation of pH-stable iron (III) sulphate products, thereby forming a slurry comprising a metal value-containing leach solution and a solid leach residue containing pH-stable iron (III) sulphate products and environmentally stable iron-arsenic and/or iron-antimony products; (c) separating the metal value-containing leach solution from the solid leach residue; (d) recovering the metal value (s) from the metal value-containing leach solution; and (e) recovering precious metal values, if present, in the solid leach residue by cyanide leaching.
