Water containing sulfuric acid and at least one non ionizing surfactant for the extraction of metal materials containing sulfur

摘要

In an aqueous solution at 23 ° C, a surfactant concentration of 0.1% to 0.3% by weight is 2% H2SO4, resulting in a reduction of the glass contact angle between 10 ° and 40 °. Surfactants are non ionizing substances, including: alcoxylatos de alcohol, alcoxilatos de polyphenol, codiploglucidos, n-alcoxidoxi amidas de acido Grasso, oxide propieno and / or oxide de butileno, Estes sorbitan, biglicer, et al; selected sulfuric acid oils, anionico de Grado, alcohol sulphatos alsuffulates, 2. Sulfates, n-acil sarcoinatos, glycerate sulfates, cerates, asphaltenes, etc;2. Cation selected from tetrahedral salts, pyridane salts and amino oxides; or anode selected from preparation consisting of anthrax acid and at least one unsaturated monomer ethylene. The ingredients come into contact with the metal containing material to obtain a metal rich mother liquor. The metal is copper. The mother liquor containing copper is extracted in the organic phase, transferred from the compound forming agent dissolved in the organic environment, and then transferred from the organic solution to the electrochemical method by aqueous sulfuric acid.
