Chemical process for recovering alkali metals and alkaline earth metals

Halides of alkali metals and of alkaline earth metals ("metals") are reduced by gallium, indium or thallium ("reducing metals") at temperatures below their boiling points at vapour pressures at which the gaseous monohalides of the reducing metals are formed. The amount of the reducing metals is calculated to be large enough both for the reduction of the metal halides and also for the simultaneous dissolution of the metals formed. For example: MgCl2(s) + 2Ga(1) = <0> Mg <0> (1)GaCl(g); 900 DEG K, 0.02 mm Hg From the melt formed, the metal is distilled off and condensed, and the metal-free reducing metal is reused for the metal halide reduction. The monohalide of the reducing metal is oxidised, the reducing metal oxide is reduced to the reducing metal and this is also reused in the halide reduction. The continuous process conditions, the loss-free circulation of the reducing metal, the utilisation of the heat of exothermic processes and a minimal requirement of electrical transport energy enable a high economic efficiency of the recovery of alkali metals and alkali earth metals according to the invention.

Process for removing, separating and concentrating lead, thallium, alkali metals and alkaline earth metals from concentrated matrices using macrocyclic polyether cryptand ligands bonded to inorganic supports

A method for the removal, separation, and concentration of alkali metal, alkaline earth metal, Pb and/or Tl cations from a source solution which may contain larger concentrations of other ions comprises bringing the source solution into contact with a compound comprising an oxygen donor macrocycle-containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The ligand portion(s) of the compound has affinity for alkali metal, alkaline earth metal, Pb and/or Tl thereby removing them from the source solution. The alkali metal, alkaline earth metal, Pb and/or Tl cations are then removed from the compound through contact with a much smaller volume of a receiving solution in which these cations are either soluble or which has greater affinity for such cations than does the oxygen donor macrocyclic ligand thereby quantitatively stripping the complexed cations from the ligand and recovering them in concentrated form in said receiving solution. The concentrated cations thus removed may be further separated and recovered by known methods. The process is useful in the removal of alkali metal, alkaline earth metal, Pb and Tl cations from a variety of source solutions such as from semiconductor, nuclear waste cleanup, metals refining, electric power, and other industrial enterprises. The invention is also drawn to the oxygen donor macrocycle-containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

Autogenous roasting of iron ore

Iron ore concentrate is converted to magnetic gamma hematite in an autogenous roasting operation which is self-sustaining. The iron ore concentrate is preheated and contained magnetite is oxidized to hematite. Hematite is reduced to magnetite using carbon monoxide. After cooling, the magnetite is oxidatively exothermically converted to magnetic gamma hematite. The thermal energy resulting from the latter step is recycled to the preheating and reduction steps while thermal energy resulting from the cooling step also is recycled to those steps. The magnetic gamma hematite may be subjected to magnetic separation to produce a very low silica high purity iron oxide concentrate, which may be blended with high silica concentrate to provide a pellet feed for making blast furnace feed pellets. <IMAGE>
