摘要： Enriched titanium hydrochloric acid extract residue is provided, for use as the feed stock in the preparation of titanium pigment by sulfuric acid process. The present invention belongs to the field of the preparation of titanium pigment and particularly, relates to the enriched titanium hydrochloric acid extract residue prepared from ilmenite by hydrochloric acid leaching, its use and the method of preparing titanium pigment. The method for preparing titanium pigment using the enriched titanium hydrochloric acid extract residue can effectively utilize the fine ilmenite in Panxi area (the utilization rate is almost 100%), obtain the titanium sulfate solution with an ultralow ratio of iron to titanium dioxide (Fe/TiO2) and double the throughput of digesting equipment. Said method can simultaneously spare two steps of iron removal by freezing and titanium sulfate solution concentration with much energy consumption, reduce the times of washing with metatitanic acid, thereby, both of the discharge of acid waste water and the production of FeSO4 are reduced. Said method provides a feed stock selection for preparing titanium pigment by sulfuric acid process.

摘要： This invention relates to a hydrometallurgical process for extracting platinum group metals (PGMs), gold, silver and base metals from a flotation concentrate (10) containing sulphide minerals such as pentlandite and chalcopyrite, along with pyrite and pyrrhotite. The process includes a modified pressure oxidation step (12) to selectively separate base metals into sulphate medium (14), from the PGMs. The modified pressure oxidation step (12) partially or completely oxidizes sulphide minerals to produce a N product slurry (14) containing base metal sulphates in solution and a solid residue containing PGMs along with sulphate and elemental sulphur. The solid residue is subjected to a thermal treatment (18) to remove sulphate and elemental sulphur from the solid residue, and to condition the PGMs to be soluble in chloride medium. The treated solid residue is the subjected to PGM recovery by leaching in chloride leaching medium (20) to recover the PGMs.

摘要： Disclosed is a method and apparatus for recovering rare metal, which separates and collects rare metals by making use of chemical actions in an efficient combination of adsorption and separation, thereby reducing work load and improving work safety. The method for recycling rare metals includes a leaching step in which a rare metal of palladium, platinum, and rhodium is mixed with hydrochloric acid into a hydrochloric acid mixture, which is then stirred at one atmospheric pressure or lower at a temperature from 50 to 90 degrees Centigrade. The vapor resulting from the stirring is condensed, and the hydrochloric acid resulting from the condensing is fed back to the original hydrochloric acid mixture to produce a hydrochloric acid leaching solution. The hydrochloric acid leaching solution produced in the leaching step is used to collect the rare metals.

摘要： The invention relates to non-ferrous metallurgy and can be used for extracting beryllium from genthelvite and bertrandite groups when processing the raw minerals (ores, concentrates) by heap and vat leaching. The objective of the invention is to disclose a method of teaching beryllium from danalite (Fe8(BeSiO4)6S2), genthelvite (Zn8(BeSiO4)6S2), helvite (Mg8(BeSiO4)6S2), chrysoberyl, euclase, and bertrandite, thus expanding the range of raw minerals used for processing and providing more economical production and improved environmental impact via use of an effective reagent at low temperatures by hydrochemical method. The offered method is beneficial both economically and ecologically, as the alternate modern pyrometallurgical method of beryllium extraction has the following drawbacks: emission of toxic gases, high energy requirements, and the need for fireproof materials. The newly developed method is recommended as a basis for the innovative technology of beryllium extraction from genthelvite and bertrandite concentrates and ores.
