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： Metallic lead is obtained from lead sulfide ores or concentrates by subjecting the concentrate to a drying step followed by halogenating the dried concentrate in a dry atmosphere at a temperature in the range of 90.degree. to about 120.degree. C. Thereafter the halogenated mixture is subjected to a water wash and leached with a brine solution. The brine solution is then filtered to separate elemental sulfur and residue from the solubilized lead halide, the latter being then crystallized and subjected to fused salt electrolysis to recover metallic lead.

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.

摘要： Lead values may be recovered from lead bearing sources such as lead sulfide in improved purity. The improved purity is obtained by subjecting soluble lead halides formed by the halogenation of lead sulfide and brine leaching the chlorinated product prior to treatment with a reducing agent followed by filtration and further treatment with an oxidizing agent whereby impurities as represented by other metal values are removed.
