    • The present invention process and compositions remove heavy metal ions, such as cadmium, copper, lead, nickel, arsenic, manganese and mercury ions from wet-process phosphoric acid by providing a simple, single-step process that uses relatively small amounts of reagent. The process involves treating either the crude acid prior to gypsum filtration or the filtered acid with an organic precipitating agent composition, precipitating metals such as copper, cadmium, nickel, mercury, zinc, and separating the precipitate by either filtration or flotation, to produce phosphoric acid with reduced levels of the metals. The compositions of the present invention include a diorgano dithiophosphinic acid (or alkali metal or ammonia salts thereof), a first dithiophosphoric acid (of alkali metal or ammonia salts thereof) with alkyl or alkylaryl or aralkyl moieties, and optionally a second diaryl dithiophosphoric acid (or alkali metal or ammonia salts thereof).

    • The invention includes methods of separating actinides from lanthanides. A regio-/stereo-specific dithiophosphinic acid having organic moieties is provided in an organic solvent which is then contacted with an acidic media containing an actinide and a lanthanide. The method can extend to separating actinides from one another. Actinides are extracted as a complex with the dithiophosphinic acid. Separation compositions include an aqueous phase, an organic phase, dithiophosphinic acid, and at least one actinide. The compositions may include additional actinides and/or lanthanides. The invention includes a method of producing a dithiophosphinic acid comprising at least two organic moieties selected from aromatics and alkyls, each moiety having at least one functional group. A source of sulfur is reacted with a halophosphine. An ammonium salt of the dithiophosphinic acid product is precipitated out of the reaction mixture. The precipitated salt is dissolved in ether. The ether is removed to yield the dithiophosphinic acid.

    • The invention is a novel process arrangement for producing pure zinc chemicals from the minor flow of a calcining-dissolving-electrolysis type of a preparation process of zinc. The invention is based on the fact that part of the production of the zinc sulphate-containing solution obtained from the dissolution of the calcining-dissolving-electrolysis plant is directed to the preparation of zinc chemicals. The actual recovery process of zinc, which is based on electrolysis, is not disturbed, as only part of the production of the zinc sulphate solution is directed to the preparation of zinc chemicals. The extraction process is based on the use of any organically substituted phosphoric acid or organically substituted thiophosphinic acid. The strong acid solution, which is generated as a by-product in the extraction process of zinc, is recycled back to the calcining-dissolving-electrolysis type of a preparation process of zinc.

    • A process for separating metallic ions, in particular nickel ions, from aqueous solutions comprises a first stage in which the solutions undergo liquid membrane permeation and a second stage in which the enriched solutions undergo ordinary solvent extraction. The membrane phase from the first stage is used as the solvent phase during the second stage. The membrane phase contains a sulphur-containing organic phosphate compounds, the aqueous stripping phase has a mineral acid content between 1 and 5 mol/l, the ratio of the aqueous solution phase used to the solvent phase and the membrane phase is always greater than 1, and the liquid membrane permeation and the solvent extraction are carried out in a mixer-separator type of apparatus in which the separators are vertical and the static differential height between the mixer and separator can be chosen at will.
