摘要： A process for removing molybdenum from uranium bearing solutions reduces molybdenum contamination of uranium product. The process employs solvent extraction techniques to remove molybdenum by using a molybdenum-selective extraction reagent of the chelating hydroxy-oxime type. The molybdenum-loaded extractant is stripped with dilute alkali for reuse. Where the uranium bearing solution originates from a solvent extraction process, a pretreatment stage is applied using an agent to remove entrained uranium extractant.

摘要： Nickel and cobalt is leached selectively from a copper-nickel-cobalt sulphide concentrate by the use of chlorine gas and oxygen gas (air) at 130 C - 160 C in an autoclave. A good separation is achieved between nickel and cobalt which goes into solution, and the copper which remains in the residue as a sulphide. This is achieved by controlling the amount of chlorine/oxygen gas into the autoclave by using the concentration of copper (II)-ions, (Cu -ions), in the filtrate coming from the autoclave as a controller/adjuster. The ratio between chlorine gas and oxygen gas in the gas mixture is controlled by the pH-value, the acid content, in the filtrate from the autoclave.
摘要翻译：通过在高压釜中使用氯气和氧气（空气）在130℃-160℃下，从铜 - 镍 - 钴硫化物浓缩物中选择性地浸出镍和钴。在进入溶液的镍和钴之间实现良好的分离，残留物中作为硫化物保留的铜。通过使用来自高压釜的滤液中的铜（II） - （Cu ++离子）的浓度作为控制器/调节器，通过控制氯/氧气进入高压釜的量来实现。气体混合物中氯气与氧气之间的比例由高压釜中的滤液中的pH值（酸含量）来控制。

摘要： A hydrometallurgical process for the recovery of precious metal values from refractory precious metal ore materials containing organic carbonaceous matter in which solubilized gold complexes are absorbed by leaching the ore with a thiosulfate lixiviant. A heap (1) of such particulate ore material is contacted with a lixiviant solution (10) at conditions conducive to the formation of stable precious metal thiosulfate complexes. Thiosulfate lixiviant is then recovered from the body of the ore particulates after a period of contact sufficient for the lixiviant solution to become pregnant (20) with precious metal values, which values are then recovered from the lixiviant solution (80).

摘要： Method for the recovery of zinc, copper and lead of oxidized and/or sulfurized ores and materials from various feedstocks by lixiviation with a concentrated solution of sal ammoniac, resulting in the formation of the corresponding amines, and separation of those metals from the fertile solution obtained by means of organic acid extractants (cationic extractants and/or chelators) which are neutralized by the amine regenerating the original solution of sal ammoniac. The copper and zinc which separately have passed the corresponding organic phase are reextracted therefrom taking advantage of the sulphuric acid obtained in the electrolysis of the corresponding solution. The lead is separated by crystallization and obtained in the form of chloride.

摘要： In a method for separating interfering elements, namely arsenic, antimony, bismuth and/or iron, from valuable metal electrolyte solutions by solvent extraction and subsequent recovery of the above-mentioned interfering elements, an aqueous mineral acid solution of the valuable metal electrolytes is added to a slightly water-soluble organic solvent containing one or more hydroxamic acids and the two phases are intimately mixed. The sulphides of arsenic, antimony and bismuth are precipitated from the organic phase, the sulphides are separated and the extracted iron is then re-extracted and recovered in an aqueous phase with a water-soluble complex builder. Before the sulphide precipitation, the organic phase is placed in contact with water for a sufficient time to permit re-extraction and if necessary the re-extracted arsenic and/or antimony in the aqueous phase is precipitated by reduction in a manner known per se and reprocessed as a by-product.
