摘要： Processes are provided for the selective recovery of lithium from brines using aqueous redox reactions, involving lithium extraction into a particulate ferric phosphate solid in the form of an iron (III) heterosite, in the presence of a reducing agent capable of reducing ionic lithium, at a controlled lithium extraction pH. Lithium elution involves exposing the loaded lithium ferrous phosphate solids, in the form of lithium iron (II) triphylite, to an oxidizing agent capable of mediating the oxidation of the sequestered atomic lithium. This is carried out at a controlled acidic lithium elution pH. Conditions in the lithium extraction and elution steps are provided so that a concentrated liquid lithium eluate is provided to subsequent steps of impurity removal and lithium carbonate precipitation.

摘要： Niobate-based octahedral molecular sieves having significant activity for multivalent cations and a method for synthesizing such sieves are disclosed. The sieves have a net negatively charged octahedral framework, comprising niobium, oxygen, and octahedrally coordinated lower valence transition metals. The framework can be charge balanced by the occluded alkali cation from the synthesis method. The alkali cation can be exchanged for other contaminant metal ions. The ion-exchanged niobate-based octahedral molecular sieve can be backexchanged in acidic solutions to yield a solution concentrated in the contaminant metal. Alternatively, the ion-exchanged niobate-based octahedral molecular sieve can be thermally converted to a durable perovskite phase waste form.

摘要： A process is provided for recovering a saline mineral from an ore containing the saline mineral and impurities. In one aspect, the process generally includes the steps of separating a first portion of impurities from the ore by density separation, electrostatically separating a second portion of impurities from the ore, and magnetically separating a third portion of impurities from the ore. The process can further include the steps of crushing the ore and dividing the crushed ore into a plurality of size fractions before the above-referenced separating steps. In another aspect, the process includes the steps of calcining the ore and subsequently separating a first portion of impurities by density separation. Indirect heating may be utilized for the calcining process and, preferably, calcining gases are recycled and utilized for heating fluidizing another portion of ore. Water vapor may be condensed from the calcining gas and utilized for other purposes.
