Abstract: DONDE EL AGENTE TENSIOACTIVO, EN UNA CONCENTRACION DE 0,1% A 0,3% EN PESO EN UNA SOLUCION ACUOSA 2% H2SO4, A 23°C CONDUCE A UNA REDUCCION DEL ANGULO DE CONTACTO EN EL VIDRIO DESPUES DE 1 s ENTRE 10° Y 40°. EL AGENTE TENSIOACTIVO ES NO IONICO SELECCIONADO DE ALCOXILATOS DE ALCOHOL, ALCOXILATOS DE ALQUILFENOL, ALQUILPOLIGLUCOSIDOS, N-ALCOXIPOLIHIDROXI-AMIDAS DE ACIDO GRASO, OXIDO DE PROPILENO Y/O OXIDO DE BUTILENO, ESTERES SORBITAN, BISGLICERIDOS, ENTRE OTROS; ANIONICO SELECCIONADO DE SULFATOS DE ALCOHOL GRASO, ALCOHOLES ALIFATICOS SULFATADOS, ALCANSULFONATOS, N-ACIL SARCOSINATOS, SULFONATOS DE GLICERIL ESTER DE ACIDO GRASO, TAURATOS DE ACILO, ACIDO ALQUILSUCCINICO, ENTRE OTROS; CATIONICO SELECCIONADO DE SALES TETRAAQUILAMONIO, SAL IMIDAZOLINIO Y OXIDOS DE AMINA; O ANFOTERO SELECCIONADO DE AGENTES QUE COMPRENDEN ACIDOS CARBOXILICOS Y POR LO MENOS UNA UNIDAD DE MONOMERO ETILENICAMENTE NO SATURADO. LA COMPOSICION SE PONE EN CONTACTO CON MATERIALES QUE CONTIENEN METALES, PARA OBTENER UN LICOR MADRE ENRIQUECIDO CON METAL. EL METAL ES COBRE, Y EL LICOR MADRE QUE LO CONTIENE ES TRANSFERIDO EN UNA FASE ORGANICA POR EXTRACCION CON UN AGENTE FORMADOR DE COMPLEJO SOLUBLE EN UN MEDIO ORGANICO, SIENDO TRANSFERIDO DE LA SOLUCION ORGANICA POR MEDIO DE ACIDO SULFURICO EN UNA FASE ACUOSA PARA SER OBTENIDO DEL MISMO POR UN METODO ELECTROQUIMICO

Abstract: Disclosed is an aqueous composition which comprises sulfuric acid and at least one surfactant, wherein the surfactant, in a concentration of from 0.1 to 0.3% by weight in a 2% strength aqueous H2SO4 solution, at 23 degrees C, leads to a reduction in the contact angle on glass after 1 second by at least 10 degrees, wherein the composition has a contact angle on glass of less than 40 degrees, and wherein the surfactant is selected from a list as described in the specification. Also disclosed is a process for extracting metal from metal-containing materials, comprising: (a) provision of an optionally milled metal-containing material, (b) provision of the above composition, (c) bringing of the metal-containing material into contact with the composition and obtaining a mother liquor enriched with metal.
