摘要： A PROCESS FOR THE PREPARATION OF SMOOTH, DENSE, FREEFLOWING HIGH PURITY METAL GRANULES BY REDUCTION OF SMOOTH, DENSE, FREE-FLOWING HIGH PURITY METAL OXIDE GRANULES. THE OXIDE GRANULES ARE CONTACTED BY REDUCING GAS AT AN ELEVATED TEMPERATURE AND REDUCED AS A MOVING BODY IN THE PRESENCE OF MINUTE REFRACTORY OXIDE PARTICLES THAT ADHERE TO THE SMOOTH SURFACES OF THE METAL OXIDE GRANULES AND SUBSTANTIALLY PREVENT SINTERING TOGETHER THEREOF DURING

REDUCTION. THE CONCENTRATION OF MINUTE REFRACTORY PARTICLES REQUIRED TO PREVENT INTERGRANULAR SINTERING IS SO SMALL THAT THE PURITY OF THE REDUCED METAL GRANULES IS SIMILAR TO THAT OF THE METAL OXIDE GRANULES WITHOUT THE NEED FOR ANY TREATMENT TO SEPARATE REFRACTORY PARTICLES FROM THE GRANULES AFTER REDUCTION.

摘要： A solvent extraction process for the improved separation of copper from cobalt in chloride solutions in which an organic solution containing an amine solvent, such as tri-iso-octylamine, is cycled around a closed organic circuit comprising in turn co-extraction of cobalt and copper from the chloride solution, preferential stripping of cobalt from the organic solution into water or dilute chloride solution thereby forming a cobalt eluate, stripping of copper from the organic, and return of the regenerated organic to the co-extraction step. The invention comprises dividing the organic into two streams, coextracting cobalt and copper from the chloride solution into one stream, preferentially extracting copper from the cobalt eluate into the other stream, and combining the two streams for preferential cobalt stripping therefrom, thereby forming a closed preferential cobalt stripping, preferential copper extracting circuit and producing a purified cobalt eluate.
摘要翻译：用于在氯化物溶液中改善铜与钴的分离的溶剂萃取方法，其中将含有胺溶剂的有机溶液（例如三异辛基胺）围绕封闭的有机回路循环，所述闭合有机回路包括依次共萃取钴和来自氯化物溶液的铜，优先将钴从有机溶液中汽提到水或稀氯化物溶液中，由此形成钴洗脱液，从有机物中剥离铜，并将再生有机物返回共萃取步骤。本发明包括将有机物分成两股，将氯化物溶液中的钴和铜共萃取成一股料流，优先将铜从钴洗脱液中提取到另一股料流中，并将两股料流合并，从而形成优质的钴封闭的优选钴剥离，优选铜提取回路和生产纯化的钴洗脱液。

摘要： A method and apparatus for thermal treatment of solid particles in fluidized beds and carrying out of heat treatments and other reactions therein at elevated temperatures such as formation of metal oxides by the endothermic reaction of metal chlorides with water. An explosive mixture of gases is supplied to a fluidized bed of solid particles in a reactor as a multiplicity of separated streams, each stream is maintained at a temperature below the ignition temperature of the mixture by cooling a portion thereof outside the reactor, and at a velocity greater than the ignition velocity of the mixture by supplying the mixture under sufficient pressure, and the mixture is then combusted in the bed to produce hot fluidizing gases, thereby maintaining the bed in a fluidized condition at an elevated temperature and providing a suitable environment for the conduct of heat treatments and other reactions.
