    Abstract: A process for the production of metal fluorides comprising introducing a predetermined weight of anhydrous hydrofluoric acid into a reaction vessel and initiate a mixing action, preheating a predetermined weight of anhydrous metal to a predetermined reaction temperature, introducing aliquots of the anhydrous metal into the reaction vessel at intervals until the entire predetermined weight of the anhydrous metal has been added, removing excess anhydrous hydrofluoric acid from the reaction vessel, and remove a metal fluoride resultant product from the reaction vessel.

    Abstract: The present invention relates to a field of preparing high-purity ferric chloride from hydrochloric solutions containing impurities. More specifically the invention concerns a ferric iron extraction from water solutions as a result of concentrated hydrochloric acid interaction with iron-containing concentrates, as a result of multi-stage extraction of ferric chloride from solutions of complicated composition and due to processing of industrial wastes, including spent etching solutions of metallurgical plants after chlorination. The essence of the invention is that the proposed method includes two stages of concentration, extraction, and stripping steps. As an extracting agent use is made of aliphatic alcohol, predominantly octanol-1, octanol-2, 2-ethylgexanol, and decanol-1 or their mixtures. The alcohol content in organic phase is up to 100 %. Attained technical result consists in obtaining high-purity ferric chloride solution with not less than 300 kg/m3 FeCl3 concentration. Ferric chloride recovery is 96-98 % irrespective of the nature of impurities present in a feed hydrochloric solution concurrently with the limitation of waste solutions and optimization of material flows and equipment used. The resulting ferric chloride solutions are feasible for further processing in high performance installations of spray roasting which permit combine in one process receiving of high-purity ferric oxide and regenerated hydrochloric acid of high concentration.
