摘要： A process for extracting gallium from an aqueous gallium-bearing acidic solution comprises: a) providing a quantity of phosphorus within the aqueous gallium-bearing solution, the phosphorus being provided in an aqueous soluble form and being substantially dissolved within the aqueous solution, the aqueous gallium-bearing solution having dissolved phosphorus defining a first aqueous phase; b) intermixing the aqueous gallium-bearing solution having the quantity of aqueous soluble dissolved phosphorus with a first organic phase comprising a quantity of an alkylated 8-hydroxyquinoline; c) separating the intermixed first aqueous phase and first organic phases into a second aqueous phase and a second organic phase, the quantities of aqueous soluble phosphorus and alkylated 8-hydroxyquinoline being effective to extract gallium from the aqueous gallium-bearing solution to provide a gallium concentration in the second organic phase which is greater than a gallium concentration in the first organic phase and to provide a gallium concentration in the second aqueous phase which is less than a gallium concentration in the first aqueous phase, the gallium concentration in the second organic phase being greater than if no aqueous soluble phosphorus were present in the first aqueous solution; and d) stripping gallium from the second organic phase with an acid solution.

摘要： The present process involves an improvement in the hydrometallurgical recovery of metal values from metal bearing sources such as ores and the like. When subjecting a metal bearing source to a reductive roast in a reducing atmosphere followed by cooling the reduced metal bearing source, extracting the cooled source and recovering the resultant nickel value, it is possible to utilize a smaller amount of an additive which assists in the recovery of metal values by scrubbing the off-gases from the reductive roast utilizing a fresh metal bearing source feed as the scrubbing material.

摘要： The present process involves an improvement in the hydrometallurgical recovery of metal values from metal bearing sources such as ores and the like. The desired metal values are recovered by subjecting a metal bearing source to a reductive roast in a reducing atmosphere after having treated said source with at least one additive. Following the reductive roast the reduced metal bearing source is cooled and extracted by a leaching operation. The separation of various metal values in the metal bearing source may be effected by adding a solid adsorbent to the leach solution whereby selective metal ions are adsorbed thereon. The improvement in the present process comprises pretreating the solid adsorbent prior to use thereof with an acid thereby increasing the loading capacity of the metal ions in the adsorbents as well as kinetics of metal adsorption.
