摘要： An arsenic-recovery process primarily for use in conjunction with the hydrometallurgical processing of arsenic-containing materials for metal recovery. Arsenic is recovered from ferric arsenate by reaction with sodium hydroxide in accordance with the following general reaction:3NaOH+FeAsO.sub.4 .fwdarw.Na.sub.3 AsO.sub.4 +Fe(OH).sub.3During the processing of high arsenic materials such as smelter flue dust, extremely insoluble ferric-arsenic compounds are generated to immobilize the arsenic during leaching of the metals. The arsenic may be recovered in saleable form from the arsenic-containing residues by leaching with sodium hydroxide and crystallizing the arsenic salts from the leach residue.

摘要： An improvement in conventional processes for recovering metal values from sulfide ores containing lead, zinc and silver sulfides in which process the metal sulfides are converted to chlorides by chlorination followed by solubilization of the chlorides with a sodium chloride leach and subsequent recovery of the metals from their chlorides in accordance with a conventional flow sheet including crystallization, cementation, precipitation, fused salt electrolysis, etc., with chlorine being recovered for reuse by electrolysis of the sodium chloride leach solution substantially depleted of lead, silver and zinc, the improvement being a pollution-free process which comprises:1. recycling the sodium chloride solution depleted of a major percentage of lead and silver to the sodium chloride or brine leaching step; and2. controlling the concentration of zinc and other impurities in the sodium chloride or brine leaching solution by bleeding a portion from the recycle stream of (1) above, removing lead, zinc and other metal impurities from the bleed stream, electrolyzing the bleed stream to produce chlorine, sodium hydroxide and a weak sodium chloride solution followed by recycle of the chlorine to the dry chlorination step and weak sodium chloride solution, after concentration, to the leach solution to control the concentration of zinc chloride and other impurities in the leach solution. A further improvement is the use of an alternate dry chlorination procedure for the sulfide ores and, particularly, ores such as the tetrahedrite-tennantite series which are more satisfactorily chloridized by dry chlorination than by wet chlorination. Another improvement is use of a flow sheet by which no impurities are removed from the process in the form of chlorides so that no chlorine is lost from the system.

摘要： This invention discloses processes for the treatment of coal and coal derivatives in order to remove contaminates to produce a high purity coal product. The processes generally comprise a sequential acid leaching in which a hydrofluoric acid leach is followed by a hydrochloric acid leach. The pyrite and other heavy metals from the coal are removed by physical separation, either gravity or magnetic separation. The leached coal is then treated either by a washing and drying step or by a heat treatment to remove volatile halides. The HF acid and the HCl acid leachates are recovered for regeneration of the respective leachates and are recycled for use in the leaching steps. In additional processing, the coal may be pre-treated by a mild HCl acid leach and by pre-drying or physical beneficiation of the coal feedstock.

摘要： A process for separating precious metals from an MnO.sub.2, sulfidic or carbonaceous refractory ore or refractory feed such as tailings is provided. The process includes the step of leaching a feed with a leach liquor that includes an acid selected from the group of HCl and H.sub.2 SO.sub.4 in the presence of MnO.sub.2 and a reductant. A source of chloride ion is added to the leach sufficient to dissolve at least about 50% of the precious metals present in the ore. A portion of the leach is removed and precious metals are recovered from the removed portion. A portion of the chloride carrier is recycled to the leach to carry chloride values to the leach. In one embodiment, HCl is regenerated by pyrohydrolysis, which minimizes harmful waste products. The present process can advantageously avoid the use of noxious reagents.

摘要： The present invention provides processes for the continuous removal of contaminants from coal to produce a clean purified fuel. The processes generally comprise producing a clean coal product having a mineral matter content of less than about 5 percent by weight from coal and coal derivatives by leaching feed coal crushed or sized to less than about 1 inch with a mixture of hydrochloric and hydrofluoric acids comprising less than about 70 weight percent HF and less than about 38 weight percent HCl at atmospheric pressure and at a temperature below the boiling point of the acid mixture. One embodiment of the present invention provides a process for producing a coal product with 5 percent ash content or less comprising comminuting raw coal or other coal-derived feed material to a size less than about 10 mm; leaching the comminuted coal with a mixture of HF and HCl comprising less than about 70 percent by weight HF and less than 38 percent by weight HCl at atmospheric pressure and a temperature below boiling, preferably ambient; separating the leached residue from the spent acid; washing the leached residue substantially free of spent acids and dissolved solids; separating pyrite from the coal by physical means; reducing halogens on the coal to an acceptable level by thermal treatment; and regenerating the mixture of HF and HCl by dual pyrohydrolysis and sulfation of the spent acids to recover substantially all of the fluorine value except for that reporting to waste as MgF.sub.2, either as HF or as volatile fluorides which are recycled. Another embodiment of the invention provides processes for producing HF, HCl, and mixtures thereof from complex aqueous streams containing at least two metal halide salts one of which will pyrohydrolyze in the presence of water vapor to form hydrogen halide and the metal oxide and one of which will not, but will in the presence of water vapor, SO.sub.2 and oxygen form hydrogen halide and metal sulfate.

摘要： A novel process for the recovery of alumina and potassium sulfate from alunite is provided comprising leaching the alunite with potassium hydroxide to which no sodium materials have been added, said leach solution being saturated with potassium sulfate. Aluminum values are solubilized into the leachate, and potassium and sulfur values are rendered soluble, but remain in the residue. The leachate is desilicated if necessary, preferably with lime, and aluminum trihydroxide is precipitated therefrom, followed by calcining to alumina product. The residue is leached to solubilize potassium sulfate in a secondary leach and the potassium sulfate product crystallized therefrom. Potassium hydroxide is regenerated from a portion of the potassium sulfate secondary leachate by several methods.Novel procedures for regenerating alkali metal hydroxides from the corresponding sulfates are also provided including routes involving formates and carbonates as intermediates and pyrohydrolysis.
