  • Publication number: 20100074836
    Abstract: Systems and methods for the recovery of iodine are described. In particular, recovery systems and methods produce an iodine complex from an aqueous brine containing iodide. A head tank for maintains a supply of the brine, a pH controller acidifies brine received from the head tank and an oxidizer converts iodide in the acidified brine to elemental iodine. At least one activated carbon contactor module is removably inserted into a stream of the oxidized brine provided by the oxidizer and binds the molecular iodine to form the iodine complex. A container may enclose the head tank, the pH controller and the oxidizer in order to facilitate transportation of the system and performance of the methods and processes in proximity to a brine source. The brine may be employed or associated with oilfield operations.

  • Patent number: 5232490
    Abstract: 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.

  • Patent number: 4743271
    Abstract: 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.

  • Patent number: 4695290
    Abstract: 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.

  • Patent number: 4618480
    Abstract: 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.

  • Patent number: 4428912
    Abstract: Alkali and alkaline earth metal chlorides contained in a residue of a chlorination process of a feed material of bauxite or clay associated with coal are removed by the addition of sulfuric acid which causes their conversion to their sulfate form, and the simultaneous production of hydrochloric acid. The residue, which has been rendered environmentally acceptable, can be disposed of readily, for example, to an ash pond or disposal area for flue gas desulfurization sludges. The hydrochloric acid is then recycled to the chlorination process. The hydrochloric acid may be utilized, for example, as a binder of the feed material, to prechloridize the feed material or as a portion of the leach solution when the chlorination process is a hydrochloric acid leach.

  • Patent number: 4423012
    Abstract: Improvement in electrowinning manganese dioxide, or zinc in which the relative concentration of manganese or zinc ions to impurities is enhanced by selectively extracting manganese or zinc ions from a bleed taken from the electrowinning feed stream with an organic extractant, while rejecting impurities, stripping the loaded organics with spent electrolyte, and recycling loaded strip to the electrowinning feed. Stripped organic may be regenerated with an alkaline agent such as calcium oxide or magnesium oxide prior to recycle, and pH may be controlled during extraction by the same means.

  • Patent number: 4288414
    Abstract: A process for recovering aluminum from clays associated with coal or bauxite containing iron, siliceous material and titanium which comprises: (a) chlorinating the clay or bauxite in an oxidizing atmosphere to selectively chlorinate and vaporize iron chloride from the remaining chlorides, (b) chlorinating the residue from step (a) in a reducing atmosphere or carbon monoxide and vaporizing the chlorides of aluminum, silicon, titanium, and the residual iron, (c) separating and recovering the formed vaporized chlorides by selective condensation. Silicon tetrachloride may be added to step (b) to suppress the chlorination of silicon. If the clay contains alkali or alkaline earth metals, then the residue of step (b) is treated with sulfuric acid to convert the soluble chlorides, e.g., gypsum, to sulfates and to regenerate a chloridizing and binder solution for pelletizing the clay or bauxite.

  • Patent number: 4276084
    Abstract: A hydrometallurgical process is used to recover lead from a lead-bearing ore concentrate. The lead-bearing ore concentrate is leached with a solution of cupric chloride in order to precipitate lead as lead chloride, produce elemental sulfur and substantially leave the balance of the ore concentrate sulfides in unreacted form. The residue of the cupric chloride leach is leached with a brine solution in order to solubilize the lead chloride to the exclusion of the balance of the residue. Thereafter, the lead chloride is crystallized from the brine solution. Elemental lead may be obtained by the reduction of the lead chloride crystals.The present process avoids air pollution problems inherent to smelting processes, allows for a high recovery of lead of 97% or greater and allows for the direct production of a high purity lead.

  • Patent number: 4244927
    Abstract: 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.
