This abstract first appeared for US patent application 20250146102 titled 'OXIDATIVE LEACHING METHODS

==Original Abstract Submitted==

disclosed are methods for leaching a material comprising copper in a zero oxidation state, wherein the method comprises contacting the material with an acidic aqueous solution having a ph less than 6 to form a leaching mixture, and oxidizing the copper with an oxidizing agent of formula limm′o. m comprises one or more metals chosen from nickel, manganese, and cobalt, m′ comprises one or more metals chosen from mg, ca, ba, al, ti, zr, zn, fe, v, mo, and w; p ranges from 1 to 1.4; q ranges from 0.6 to 2; r ranges from 0 to 1; s ranges from 2 to 4; and a total amount of copper present in the material before leaching in moles divided by a total amount of the oxidizing agent in moles, mols(cu)/mois(oa), ranges from n(m)/8 to 2 n(m); n(m)_=2(s-q)-p-roxm′ and ox is the average oxidation number of m′ determined by calculating the molar average of the most stable oxidation number for each metal, as an oxide, comprised by m′.
