Abstract

"MéTODO DE MODIFICAçãO DE VISCOSIDADE DE LAMA DE MINéRIO". A invenção refere-se a um método de diminuição da viscosidade de uma lama de minério. O método compreende a adição a uma lama de minério de um tratamento de modificação de viscosidade, como: copolímeros de anidrido maléico e diisobutileno; copolímeros de ácido acrílico e alil hidroxipropil sulfonato éter; terpolímeros de ácido acrílico, sal de ácido 2-acrilamida-2-metilpropano sulfónico e t-butil acrilamida; copolímeros de ácido acrílico e polietilenoglicol monoalil éter sulfato; e copolímeros de ácido acrílico e sal de ácido 2-acrilamida-2-metilpropano sulfónico; pentafosfonatos; polimetacrilatos; e suas misturas.
