Abstract
A method for generating metal peroxides from metal-containing raw materials is provided. The raw material is initially treated with a lixiviant salt, generating a soluble metal salt and a lixiviant base. Subsequent application of a peroxide or a source of peroxide generates the metal peroxide and also regenerates the lixiviant salt. This regenerated lixiviant salt can be recycled for application to additional raw material. Both stepwise and continuous processes are described.
Claims22
A method for producing a metal peroxide, comprising:
- obtaining a first portion of a raw material comprising an insoluble metal salt;
- contacting the raw material with a lixiviant salt to extract a metal from the raw material as a first solution comprising a soluble metal salt comprising the metal;
- contacting the first solution with a peroxide or a source of peroxide to generate a suspension comprising a solid product comprising a metal peroxide comprising the metal and to generate a second solution comprising a regenerated lixiviant salt;
- and
- separating the solid product from the second solution.

A method for producing a metal peroxide, comprising:
- obtaining a first portion of a raw material comprising a first metal in the form of an insoluble metal salt;
- contacting the raw material with a lixiviant salt to extract the first metal from the raw material as a soluble metal salt, thereby generating a first suspension comprising an extracted solid and a first solution comprising the soluble metal salt and a lixiviant base;
- separating the extracted solid from the first solution;
- contacting the first solution with a peroxide or a source of peroxide to generate a second suspension comprising a metal peroxide and to generate a second solution comprising a regenerated lixiviant salt;
- and
- separating the metal peroxide from the regenerated lixiviant salt.
