摘要： Provided is a method of manufacturing high-purity, high-quality manganese sulfate which can be immediately used for manufacturing a lithium ion secondary battery from manganese sulfate waste liquid of a wasted battery. Since impurities are removed from the manganese sulfate waste liquid by using sulfides causing no secondary contamination in the manganese sulfate waste liquid and the manganese sulfate is manufactured by performing evaporation concentration through heating, the manufacturing method is very environment-friendly and economical. Since the manganese recovering process improving the manufacturing yield of the manganese sulfate and the waste water treatment process capable of recycling the source materials and discharging waste water are integrated, the manufacturing method is very efficient and environment-friendly. The manufacturing method is applied to the recycling industry, and thus, it is possible to obtain effects of preventing environmental pollution and facilitating recycling the resources.

摘要： A process for enhancing recovery of metals, especially cobalt, from spent hydroprocessing catalysts when the spent catalyst particles are first roasted at between 400.degree. C. and 600.degree. C. and then contacted with a first aqueous solution of ammonia and an ammonium salt to recover nickel, cobalt, molybdenum, tungsten, and vanadium. The once-leached spent hydroprocessing catalysts are again leached by contacting them with a second aqueous solution of ammonium sulfate at a pH of 1 to 4.

摘要： A process for extracting a nickel product having a predetermined nickel to cobalt ratio and a mixed nickel-cobalt sulphide product having a low nickel to cobalt ratio from reduced nickel and cobalt bearing lateritic and garnieritic ores. The reduced ores are leached in one or more stages under oxidizing conditions in an aqueous ammoniacal ammonium carbonate solution. Solution from the leaching operation is treated in a multi-stage cobalt removal operation in which excess sulphidizing agent is added to one stage to effect extraction of a large quantity of cobalt from solution as a mixed nickel-cobalt sulphide precipitate. The amount of sulphidizing agent added to another stage is restricted to produce a mixed nickel-cobalt sulphide precipitate with a low Ni:Co weight ratio. The mixed sulphide precipitate is removed from each stage solution and a portion is recycled to the solution from which it was removed.

摘要： A method for preparing a cobalt sulfide/reduced graphite oxide composite includes: preparing a glycerol-cobalt precursor by taking a water-soluble cobalt salt, a micromolecular alcohol solvent, and glycerol as raw materials; mixing the glycerol-cobalt precursor with an alkali liquor to prepare a Co(OH)2 nanoflower; calcining the Co(OH)2 nanoflower to obtain a Co3O4 nanoflower; subjecting the Co3O4 nanoflower to a reaction with a water-soluble sulfur salt to obtain a COS nanoflower, and mixing the COS nanoflower with graphite oxide and carrying out a heat treatment to obtain the composite. The response characteristics of a gas sensor to NO2 gas are studied at room temperature, and the graphite is complexed with a transition metal sulfide with unique morphology to construct a unique heterostructure. While expanding the specific surface area to increase the number of adsorption sites, the heterostructure of a contact surface is used to greatly enhance the charge-transfer efficiency.

摘要： A process for preparing a molybdenum sulfide-based catalyst comprises drying a precipitated molybdenum sulfide-based catalyst precursor, for example, a wet filter cake, such that a particulate catalyst precursor, containing from 12 to 15 percent by weight water, is formed. The particulate catalyst precursor is desirably in the form of free-flowing particles. The particulate catalyst precursor is then auto-reduced. A rotary furnace that subjects the catalyst precursor to at least two zones having distinct temperatures may be conveniently used for drying, auto-reduction, or both. The staged drying and auto-reduction steps reduce the tendency of the precursor to self-heat, which is undesirable because it reduces both the activity and selectivity of the final catalyst.
