Abstract
SE REFIERE A UN PROCEDIMIENTO PARA SEPARAR EL METAL SELECCIONADO DE ENTRE EL GRUPO DE COMPUESTOS Ag, Au, Pt, Rh, ENTRE OTROS, DE LA ESCORIA QUE CONSISTE EN: A) TRITURAR LA ESCORIA PREPARADA ARTIFICIALMENTE PARA OBTENER PARTICULAS; B) PONER EN CONTACTO LA ESCORIA TRITURADA DEL PASO A) CON UNA PARTICULA MAGNETICA Y/O UNA SUSTANCIA ALTERADORA DE LA SUPERFICIE, EN PRESENCIA DE UN DISPERSANTE DANDO COMO RESULTADO LA FORMACION DE AGLOMERADOS DEL METAL Y LA PARTICULA MAGNETICA, A CAUSA DE INTERACCIONES MAGNETICAS Y/O HIDROFOBICAS; C) ANADIR UN DISPERSANTE A LA MEZCLA OBTENIDA EN EL PASO A) O B), A FIN DE QUE SE DE UNA DISPERSION QUE TENGA UNA CONCENTRACION APROPIADA; D) SEPARAR LAS PARTICULAS DE LA MEZCLA DEL PASO A) O LOS AGLOMERADOS DE LA MEZCLA DEL PASO B) O C) MEDIANTE APLICACION DE UN CAMPO MAGNETICO; E)PROCESAR LAS PARTICULAS O LOS AGLOMERADOS DEL PASO D) POR VIA DE FUNDICION, EXTRACCION Y/O REFINACION QUIMICA HUMEDA; F) DESCOMPONER LOS AGLOMERADOS DEL PASO D) Y PROCESAR EL METAL POR VIA DE FUNDICION, EXTRACCION Y/O REFINACION QUIMICA HUMEDA.IT REFERS TO A PROCEDURE TO SEPARATE THE SELECTED METAL FROM AMONG THE GROUP OF COMPOUNDS Ag, Au, Pt, Rh, AMONG OTHERS, FROM THE SLAG WHICH CONSISTS OF: A) CRUSHING THE ARTIFICIALLY PREPARED SLAG TO OBTAIN PARTICLES; B) TO CONTACT THE CRUSHED SLAG FROM STEP A) WITH A MAGNETIC PARTICLE AND / OR A SURFACE ALTERING SUBSTANCE, IN THE PRESENCE OF A DISPERSANT, RESULTING IN THE FORMATION OF AGGLOMERATES OF THE METAL AND THE MAGNETIC PARTICLE, CAUSED BY MAGNETIC INTERACTIONS AND / OR HYDROPHOBIC; C) ADD A DISPERSANT TO THE MIXTURE OBTAINED IN STEP A) OR B), IN ORDER TO GIVE A DISPERSION THAT HAS AN APPROPRIATE CONCENTRATION; D) SEPARATE THE PARTICLES FROM THE MIXTURE FROM STEP A) OR THE AGGLOMERATES FROM THE MIXTURE FROM STEP B) OR C) BY APPLYING A MAGNETIC FIELD; E) PROCESSING THE PARTICLES OR AGGLOMERATES FROM STEP D) BY METHOD OF CASTING, EXTRACTION AND / OR WET CHEMICAL REFINING; F) DECOMPOSE THE AGGLOMERATES FROM STEP D) AND PROCESS THE METAL BY WAY OF CASTING, EXTRACTION AND / OR WET CHEMICAL REFINING.
