Abstract

Patente de Invenção: "PROCESSO PARA RECUPERAçãO DE PARTìCULAS MINERAIS, PARTìCULAS METáLICAS OU PEQUENAS PEDRAS PRECIOSAS DE UMA LAMA AQUOSA ASSOCIADA COM UM CORPO DE MINéRIO OU UM DEPóSITO MINERAL OU SEU PROCESSAMENTO". Um processo para recuperação de partículas minerais, partículas metálicas ou pequenas pedras preciosas de uma lama aquosa associada com um corpo de minério ou depósito mineral ou seu processamento, a mencionada lama aquosa contendo partículas minerais, partículas metálicas ou pequenas pedras preciosas em suspensão com partículas de lama. O processo inclui adicionar uma quantidade suficiente de um agente de desfloculação à lama aquosa para causar a desfloculação das partículas de lama e produzir uma suspensão desfloculada contendo as partículas minerais, as partículas metálicas ou as pequenas pedras preciosas. A suspensão desfloculada é deixada assentar, e o material assentado contendo as partículas minerais, partículas metálicas ou pequenas pedras preciosas é recuperado.Invention Patent: "PROCESS FOR THE RECOVERY OF MINERAL PARTICLES, METALLIC PARTICLES OR SMALL PRECIOUS STONES FROM A WATER MUD ASSOCIATED WITH A BODY OF ORE OR A MINERAL DEPOSIT OR ITS PROCESSING". A process for recovering mineral particles, metallic particles or small precious stones from an aqueous sludge associated with an ore body or mineral deposit or its processing, the aforementioned aqueous sludge containing mineral particles, metallic particles or small precious stones suspended with particles of mud. The process includes adding a sufficient amount of a deflocculating agent to the aqueous slurry to cause the deflocculation of the sludge particles and producing a deflocculated suspension containing mineral particles, metal particles or small gemstones. The deflocculated suspension is allowed to settle, and the settled material containing mineral particles, metallic particles or small precious stones is recovered.
