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.
