Abstract
In one embodiment, the present disclosure relates generally to a method for recovering an element from a mixture of the element with an ionic halide. In one embodiment, the method includes treating the mixture of the element and the ionic halide with an acidic solution to dissolve the ionic halide, wherein the acidic solution comprises water and an acid and has a pH of less than 1.0 and removing the element from an aqueous solution that results after the treating step.
Claims20
A method for recovering an element from a mixture of the element with an ionic halide, the method comprising:
- treating the mixture of the element and the ionic halide with an acidic solution to dissolve the ionic halide, wherein the acidic solution comprises water and an acid and has a pH of less than 1.0;
- and
- removing the element from an aqueous solution that results after the treating.
A method for recovering silicon (Si) from a mixture of Si and sodium fluoride (NaF), the method comprising:
- treating the mixture of the Si and the NaF with an acidic solution to dissolve the NaF, wherein the acidic solution comprises water and an acid and has a pH of less than 1.0;
- and
- removing the Si from an aqueous solution that results after the treating.
A method for recovering an element from a mixture of the element with an ionic halide, the method comprising:
- producing the mixture of the element and the ionic halide during a reduction of a precursor halide formed from a complex precursor salt used to produce the element;
- treating the mixture of the element and the ionic halide with an acidic solution to dissolve the ionic halide, wherein the acidic solution comprises of water and an acid and has a pH of less than 1.0;
- and
- removing the element from an aqueous solution that results after the treating.
