摘要： A reactor comprises an outer sidewall and a bottom wall enclosing a hollow chamber comprising a lower fluidized bed zone and an upper freeboard zone. A plurality of inlets is provided for injecting at least one fluidizing medium into the fluidized bed zone and creating a swirling flow. At least one feed inlet communicates with the fluidized bed zone; and at least one product outlet is provided for removing a product from the chamber, the outlet(s) communicating with either the fluidized bed zone or the freeboard zone. The reactor has at least one internal barrier located inside the hollow chamber, and at least partly located in the fluidized bed zone. The internal barrier(s) have at least one opening within the fluidized bed zone, such as an underflow opening, to permit internal recirculation of material from the product zone to the feed zone, thereby simplifying reactor structure.

摘要： The ore which contains gold and at least one of the metals silver, copper, nickel, zinc or iron is calcined at temperatures in the range from 500.degree. to 900.degree. C. with the addition of oxygen-containing gas, thereby producing a metal-oxide-containing solids mixture and a SO.sub.2 -containing exhaust gas. The SO.sub.2 containing exhaust gas is brought in contact with aqueous solution, thereby producing a sulfite-containing solution. The solids mixture from the calcination is cooled to temperatures in the range from 50.degree. to 300.degree. C. and is stirred up with the sulfite-containing solution. Metal oxides are dissolved, and a sulfate-containing solution os formed. In a first separating zone, the sulfate-containing solution is separated from the solids, and either the solids are supplied to a gold leaching or the sulfate-containing solution is subjected to a further treatment for the separation of nonferrous metals.

摘要： A process and apparatus for forming a hardened outer shell (40) on a refractory metal workpiece (36) preferably heated in a fluidized bed of metallic oxide particles (38) in an environment of an inert gas and a reactive gas with the reactive gas either oxygen or nitrogen. The workpieces (36) are heated in the fluidized bed to a temperature between 800 F. and 1600 F. for a period of over two hours to form hardened outer shell (40) in two layers (42, 44). Outer layer (42) is an oxide or nitride layer having a thickness (T1) between 10 microns and 25 microns. Inner layer (44) is a case hardened layer of the refractory metal having a thickness (T2) between 25 microns and 75 microns. In one embodiment workpieces (56) may be cold worked by peening from finely divided metal oxide particles (54) to provide a uniform surface texture for subsequent hardening.

摘要： The invention pertains to an entrained-downflow chlorination process of fine metalliferous ores particularly containing alkali and/or alkaline earth metals greater than about 0.3% by weight as the oxide. The process includes a quenching step following the chlorination step where the chlorinated products are quenched by liquid cooling fluid spray patterns adapted to prevent solidification of the alkali and/or alkaline earth materials onto the reactor walls. The chlorinator unit of this invention prevents disruption of the chlorination process due to presence of liquids or sticky particles and it contains a quenching spray means disposed below the chlorination zone in the entrained-downflow chlorinator unit, whereby the quenching sprays prevent reactor wall buildup.

摘要： A burner for the flash oxidation of particles of metal concentrates has three downwardly directed, concentrically mounted tubes each having a venturi nozzle on the discharge end thereof. Finely divided metal concentrates introduced into the annular space between the inner tube and the intermediate tube are accelerated by high pressure oxygen introduced through the inner tube to substantially the velocity of an oxidizing gas introduced into the annular space between the intermediate tube and the outer tube. Means are provided for adjusting the extent that the nozzles on the ends of the inner tube and intermediate tube extend into the nozzles on the ends of the intermediate and outer tubes respectively.
