    Abstract: A unique production of titanium compounds and metal by sustainable methods using iron-titanium oxide starting material such as ilmenite, leucoxene, or rutile is described. Here the iron-titanium oxide compound is prepared by converting the iron portion of the compound to ferrous chloride at low temperatures by using close to stoichiometric amounts of sulfur and chlorine required for all the iron oxides and the other non-titanium oxides. The ferrous chloride thus formed is removed recovering a marketable product of ferrous chloride and the ‘sustainable’ titanium oxide starting material by additional process steps. This can be converted to ‘sustainable’ titanium metal, or titanium tetra-chloride by process shown herein for further conversions to titanium dioxide pigment by present chloride process or supplied to existing titanium sponge producers, benefitting them in having a ‘sustainable process’.

    Abstract: A fuel for splitting water into hydrogen and an oxide component comprises a substantially solid pellet formed from a solid-like mixture of a solid-state source material capable of oxidizing in water to form hydrogen and a passivation surface layer of the oxide component, and a passivation preventing agent that is substantially inert to water in an effective amount to prevent passivation of the solid-state material during oxidation. The pellets may be introduced into water or other suitable oxidizer in a controlled rate to control the rate of reaction of the source material with the oxidizer, and thereby control the rate of formation of hydrogen. Methods are described for producing the solid-like mixture in varying weight percent of source material to passivation preventing agent.

    Abstract: Apparatus and methods for mercury and precious metal recovery are provided. The apparatus includes a granulometric separator for separating a feed by particle size; a centrifugal concentrator in flow communication with the granulometric separator for isolating and concentrating an elemental mercury-containing fraction of the feed; and an accumulator tank for collecting elemental mercury from the elemental mercury-containing fraction. The accumulator tank has an inlet in flow communication with the centrifugal concentrator; an outlet; a plurality of baffles defining a serpentine flow path to slow the flow of the elemental mercury-containing fraction from the inlet to the outlet; and a mercury accumulation area for collecting elemental mercury settling from the elemental mercury-containing fraction.

  • Publication number: 20110011216
    Abstract: A process for recovering metals involving ion exchange comprising the step of recovering metal species from an ion exchange resin by elution of the resin with an eluent system containing (i) a first sulphite component comprising at least one of sulphite and bisulphite ion; and (ii) a second eluting component comprising any species which favours the ion exchange or desorption of a metal species from the resin during elution wherein the presence of the sulphite component (i) increases metal elution efficiency relative to the situation where an eluent comprises the second eluting component alone.

  • Publication number: 20100307292
    Abstract: A method by which the amount of nickel contained in an alloy having a composition represented by Sn—X—Ni can be regulated. The method of nickel concentration regulation comprises adding phosphorus to Sn—X—Ni in a molten state (wherein X is one or more elements selected from the group consisting of Ag, Zn, Cu, Bi, Au, Ti, Ge, Ga, Si, and Ce), holding the mixture at 250-400° C., and removing the resultant dross floating on the surface of the liquid phase and containing a P—Ni compound and a P—Sn—Ni compound. An example of X is copper, and the content thereof may be 0.3-5 wt %. The phosphorus may be added in the state of a Sn—P alloy. The upper limit of the amount of the phosphorus to be added may be about half the nickel amount in terms of atomic amount.

  • Patent number: 7837760
    Abstract: The invention publishes a process to increase the bioleaching speed of ores or concentrates of sulfide metal species in heaps, tailing dams, dumps, or other on-site operations. The process is characterized by the continuous inoculation of the ores or concentrates with isolated microorganisms of the Acidithiobacillus thiooxidans type, together with isolated microorganisms of the Acidithiobacillus ferrooxidans type, with or without native microorganisms, in such a way that the total concentration of microorganisms in the continuous inoculation flow is of around 1×107 cells/ml to 5,6×107 cells/ml. In particular, the invention publishes the continuous inoculation of Acidithiobacillus thiooxidans Licanantay DSM 17318 together with Acidithiobacillus ferrooxidans Wenelen DSM 16786 microorganisms, or with other native microorganisms at a concentration higher than 5×107 cells/ml.
