摘要： A process and system are provided for flash-roasting molybdenum sulfide containing slag-forming constituents. The process comprises feeding a pneumatically suspended stream of particulate molybdenum sulfide and a mixture of fuel and oxidizing gases through a nozzle into a confined furnace chamber, the fuel gas-oxidizing gas mixture exiting from the nozzle being ignited to provide a flame thereof, the flame being maintained at a condition to provide a temperature in the furnace chamber sufficient to oxidize the molybdenum sulfide and form a volatile gas comprising molybdenum trioxide. The temperature is at least sufficient to melt the slag-forming constituents such that the slag formed is sufficiently liquid to separate from the gaseous mixture and collect at a selected portion of said chamber for removal therefrom. The resulting gases in the volatile molybdenum trioxide are caused to flow from the furnace chamber to and through a condensing chamber, the temperature of the condensing chamber being controlled to condense the volatilized molybdenum trioxide and separate it from the off-gases.

摘要： A process and system are provided for flash-sublimation of molybdic oxide containing slag-forming constituents. The process comprises feeding a pneumatically suspended stream of particulate molybdic oxide and a mixture of fuel and oxidizing gases through a nozzle into a confined furnace chamber, the fuel gas-oxidizing gas mixture exiting from the nozzle being ignited to provide a flame thereof, the flame being maintained at a condition to provide a temperature in the furnace chamber in excess of that required to sublime molybdic oxide. The temperature is preferably at least sufficient to melt slag-forming constituents contained in said molybdic oxide such that the slag formed is sufficiently liquid to separate from the gaseous mixture and collect at a selected portion of the chamber for removal therefrom. The resulting gases and suspended solids including sublimed molybdenum trioxide are caused to flow from said furnace chamber to and through a condensing chamber, the temperature of the condensing chamber being controlled to above the condensing temperature of the sublimed molybdenum trioxide but below the volatilization temperature of the impurities present and thereby effect a separation of the molybdenum trioxide from the impurities. The separated molybdenum trioxide vapors are then passed to a condenser to condense and recover the molybdenum trioxide as solids and separate it from off-gases.

摘要： An aqueous solution of at least one valuable oxyanion containing molybdenum, tungsten, vanadium, or uranium is refined to lower the content of contaminant anions such as PO.sub.4.sup.-3, SO.sub.4.sup.-2, NO.sub.3.sup.-, Cl.sup.-, ClO.sub.3.sup.-, and ClO.sub.4.sup.-, by subjecting the solution to electrolysis at a pH of from 0.5 to 4.0 between a cation-permselective membrane and an anion-permselective membrane having tertiary amine or quaternary ammonium anion exchange groups, to cause contaminant anions to pass from the solution into the anolyte. Ammonium molybdates, tungstates, vanadates, and uranates are formed from the thus-refined solution by subjecting it to a second stage of electrolysis at a pH of at least 7 between a cation-permselective membrane and an anion-permselective membrane to cause valuable oxyanions to pass from the solution into an anolyte which comprises an aqueous solution of ammonia and to form the desired ammonium compound.
