Abstract
MÉTODO E UMA DISPOSIÇÃO PARA APERFEIÇOAR UM PROCESSO DE FLOTAÇÃO MINERAL. O relatório descritivo se refere a um método para aperfeiçoar um processo de flotação mineral. O método compreende adicionar coagulante(s) e/ou floculante(s) e/ou produto(s) químico(s) de flotação a uma corrente aquosa (100, 200a, 300a, 400b) de uma planta de processamento de minerais a fim de facilitar a formação de flocos incluindo partículas coloidais compreendendo metal(is) eletroquimicamente ativo(s), e a fim de formar uma corrente aquosa tratada (101, 201, 301, 401), submeter a corrente aquosa tratada (101, 201, 301, 401) à flotação de limpeza a fim de separar pelo menos algumas das partículas coloidais compreendendo metal(is) eletroquimicamente ativo(s) e pelo menos alguns dos micróbios contidos pela corrente aquosa tratada (101, 201, 301, 401) como um overflow de flotação de limpeza (103, 203, 303, 403) e a fim de formar um underflow de flotação de limpeza (104, 204, 304, 404), remover o overflow de flotação de limpeza (103, 203, 303, 403), e utilizar pelo menos parte do underflow de flotação de limpeza (104, 204, 304, 404) como água de processo em processamento de minerais. A flotação de limpeza compreende bolhas de gás, pelo menos 90% das bolhas de gás tendo um diâmetro de 0,2 a 250 µm.METHOD AND ARRANGEMENT FOR IMPROVING A MINERAL FLOTATION PROCESS. The specification relates to a method for improving a mineral flotation process. The method comprises adding coagulant(s) and/or flocculant(s) and/or flotation chemical(s) to an aqueous stream (100, 200a, 300a, 400b) of a mineral processing plant in order to to facilitate the formation of flakes including colloidal particles comprising electrochemically active metal(s), and in order to form a treated aqueous stream (101, 201, 301, 401), subjecting the treated aqueous stream (101, 201, 301 , 401) to cleaning flotation in order to separate at least some of the colloidal particles comprising electrochemically active metal(s) and at least some of the microbes contained by the aqueous stream treated (101, 201, 301, 401) as an overflow cleaning flotation (103, 203, 303, 403) and in order to form a cleaning flotation underflow (104, 204, 304, 404), remove the cleaning flotation overflow (103, 203, 303, 403) , and using at least part of the cleaning flotation underflow (104, 204, 304, 404) as process water in mineral processing. The cleaning flotation comprises gas bubbles, at least 90% of the gas bubbles having a diameter of 0.2 to 250 µm.
