    Abstract: SE REFIERE A UN PROCESO PARA LA CONCENTRACION DE UNA SUSPENSION DE PARTICULAS SOLIDAS EN UN MEDIO ACUOSO, EL CUAL COMPRENDE LA INTRODUCCION EN LA SUSPENSION DE UN FLOCULANTE POLIMERICO ORGANICO TAL COMO EL HOMOPOLIMERO DE ACRILATO DE SODIO, HOMOPOLIMERO DE ACRILAMIDA, ENTRE OTROS, Y LA ADICION DE UN SISTEMA DE AGENTES QUE COMPRENDE a) UN AGENTE OXIDANTE TAL COMO AGUA DE OZONO O PEROXIDO DE HIDROGENO, Y b) UN AGENTE DE CONTROL QUE CONTIENE i) UN COMPONENTE ACTIVADOR TAL COMO IONES DE HIERRO (II)(Fe2+), IONES DE COBRE (II)(Cu2+), ENTRE OTROS, QUE AUMENTA LA ACTIVIDAD DEL AGENTE OXIDANTE, Y ii) UN COMPONENTE SUPRESOR QUE DISMINUYE LA CONCENTRACION DEL COMPONENTE ACTIVADOR; EN DONDE LAS PARTICULAS SOLIDAS EN LA SUSPENSION SE FLOCULAN Y LUEGO SE SEDIMENTAN PARA FORMAR UNA CAPA SEDIMENTADA DE SOLIDOS EN EL MEDIO ACUOSO. DICHA SUSPENSION DE PARTICULAS SOLIDAS SE DERIVA DE OPERACIONES DE PROCESAMIENTO MINERAL, DE ENERGIA O SUSTRATOS DE RESIDUOS

    Abstract: The invention concerns a process for enriching an iron mineral from a silicate containing iron ore by inverse flotation comprising the addition of a collector or collector composition comprising at least one of the compounds of formulae RC(0)N(Z-0-X-NH2)2 (la); RC(0)N(Z-0-X-NH2)2H+ Y- (lb); in which X is an aliphatic alkylene group containing 2 to 6 carbon atoms; Z is an aliphatic alkylene group containing 2 to 6 carbon atoms; Y- is an anion; and R is a saturated or unsaturated, linear or branched, aliphatic or aromatic moiety having between 7 and 23 carbon atoms. The invention also relates to the novel compounds according to formulae (la) and (lb), compositions comprising said compounds and the use of compounds and formulations as collectors for enriching of iron mineral.
