摘要： A process for treating thermally activated metal sulfides containing copper, iron and zinc for separate recovery of zinc as zinc sulfide in which the metal sulfides are subjected to a two-stage countercurrent acid leach for the formation of copper sulfide containing acid leach residue and ferrous sulfate solution. The second-stage acid leach is performed in two steps; the first step is operated at a relatively high pulp density and high acid concentration for iron and zinc extraction, the resulting slurry diluted, and the second step is operated at a relatively low pulp density and low acid concentration for dissolution of precipitated ferrous sulfate and precipitation of any dissolved copper values by H.sub.2 S. The diluent solution for the slurry from the second-stage first step preferably is generated sulfuric acid solution from a jarosite precipitation and iron and zinc-containing solution from a subsequent activation leach. Zinc in solution from the acid leach and activation leach is precipitated as zinc sulfide in substantially pure form.

摘要： This invention relates to a process for hydrometallurgical treatment of concentrates of sulphides of copper, nickel, cobalt, lead and iron and copper-containing mattes. A first embodiment of the process includes subjecting a finely ground slurry of a sulphide concentrate to an oxidation leach at elevated temperature and pressure in the presence of an oxygen-bearing gas to preferentially leach cobalt and nickel and to convert galena to lead sulphate. The reaction mixture is heated to a further elevated temperature, in the absence of oxygen, to convert a portion of chalcopyrite to insoluble simple copper sulphides and ferrous sulphate solution and to decompose complex insoluble ferric compounds. The resulting mixture is subjected to differential flotation whereby a lead concentrate and a copper concentrate are obtained. The solution is reduced in acid content by addition of limestone, the iron is precipitated and removed, and nickel and cobalt are precipitated in the remaining solution as sulphides and recovered as a concentrate.The second embodiment of the process includes subjecting a copper-containing matte to an oxidation leach at elevated temperature and under pressure of an oxygen-bearing gas whereby a copper sulphate-containing solution is formed for use in the process of the first embodiment and solids residue is recovered as a concentrate.

摘要： An improved spacer clip for mounting on an anode header bar joined to and supporting a planar anode sheet in an electrolytic cell containing a plurality of anodes and cathodes provides improved protection against direct anode-to-cathode contact and maintenance of more uniform spacing between adjacent anodes and cathodes. The spacer clip, formed of a resilient electrically non-conducting material such as medium density polypropylene, comprises a central body defining a vertex, a pair of arms extending from the vertex adapted to fit over the header bar, and a pair of exterior wings depending from the arms and diverging to a maximum spacing coextensive with the ends of the arms and thence converging towards each other to terminate in ends substantially tangential to the supported anode sheet.

摘要： A hydrometallurgical process for treating iron containing metal sulfides for rendering iron and non-ferrous metal values active and amenable for selective extraction and separate recovery. Sulfur values can be controllably produced as elemental sulfur or as sulfuric acid to supply acid requirements of the process, while substantially obviating the discharge of sulfur-containing gases to the atmosphere. Ores and concentrates of the sulfides are thermally activated by sequentially heating and reducing said sulfides in a countercurrent flow of heating and reducing gases respectively in a reactor whereby the reaction products of the reducing gas and sulfides, together with liberated labile sulfur, are controllably combusted with oxygen to satisfy heat requirements of the thermal activation process and to convert sulfur values to SO.sub.2 gas. The activated sulfides are subjected to an acid leach in aqueous sulfuric acid for production of ferrous sulfate and evolution of H.sub.2 S gas which are separated from the solid sulfide residue containing concentrated non-ferrous metal values. The ferrous sulfate is oxidized and hydrolysed to precipitate the iron, which is removed from the system, and to regenerate sulfuric acid. At least a portion of the SO.sub.2 gas from said heating step and at least a portion of the H.sub.2 S from the acid leach are converted to sulfuric acid to satisfy the acid requirements of the process, and remaining SO.sub.2 is combined and catalytically reacted with remaining H.sub.2 S to produce elemental sulfur.The solids residue from the acid leach is subsequently subjected to further treatment for recovery of metal values.

摘要： Absorption of treatment composition into a surface layer of particulate material in a moving bed is substantially increased by spraying a major portion of the composition through a first group of nozzles and a minor portion of the composition through a second group of nozzles, the nozzles being attached to the top of a common transverse spray header which is oscillated across the moving bed. The first group of nozzles directs a plurality of substantially parallel vertical jets onto the surface of the moving bed to form therein, on combined motion of the bed and spray header, a zigzag pattern of trenches. The treatment composition is retained in these trenches as it is absorbed by adjoining particulate material. Loss of treatment composition due to run-off over a sloping or insufficiently wetted surface is avoided. The second group of nozzles is provided with deflectors which cause downwardly discharging fluid to fan out in spray curtains which together extend across the moving bed to ensure wetting of areas between the zigzag trenches.

摘要： A process for the hydrometallurigical extraction of copper values and sulphur in elemental form from copper-iron sulphides in which the sulphides are subjected to an activation leach with an acidic copper sulphate solution whereby insoluble simple copper sulphides and a solution of ferrous sulphate are obtained. After a liquid-solids separation, for the effective separation of iron from copper values, the ferrous sulphate in the solution is oxidized and hydrolyzed to precipitate the iron, which is removed from the process, and to regenerate acid solution containing sulphuric acid. The copper sulphides are treated with an oxygenbearing gas and with said regenerated sulphuric acid solution in a multiple-stage oxidizing leach to oxidize the sulphide sulphur to elemental sulphur and to liberate the copper as cupric ion for subsequent recovery in metallic form.

摘要： PARTICULATE POTASH IS GRANULATED IN A PAN GRANULATOR. THE MOIST GRANULES FROM THE PAN ARE MIXED WITH WARM RECYCLED DRY GRANULES AND TUMBLED IN A ROTATING DRUM WHEREBY THE GRANULES BECOME EQUILIBRATED IN BOTH MOISTURE CONTENT AND TEMPERATURE. THE EQUILIBRATED GRANULES ARE DRIED IN A FLUID BED DRYER AND SIZED BY SCREENING. THE OVERSIZE AND UNDERSIZE GRANULES ARE RECYCLED, VIA A PULVERIZER, TO THE PAN AND THE PRODUCT SIZE GRANULES GO TO STORAGE. THE RECYCLED DRY GRANULES ARE EITHER TAKEN FROM THE DRYER DISCHARGE OR FROM THE PRODUCT SIZE GRANULES GOING TO STORAGE. THE FINAL PRODUCT IS A GRANULATED POTASH OF IMPROVED BULK DENSITY, HARDNESS AND GRANULE SHAPE WHICH IS SUITABLE FOR USE IN BULK BLEND FERTILIZERS.
