Abstract
La presente invención se relaciona con el campo de la minería, en particular con procesos que involucran microorganismos para obtener cobre a partir de minerales y proporciona un reactivo para aumentar la recuperación de cobre en procesos de flotación de sulfuros de cobre que se caracteriza porque comprende células de microorganismos acidófilos que se seleccionan del conjunto formado por Acidithiobacillus sp, Leptospirilum ferriphilum y Acidiphillum sp, así como combinaciones de las mismas. La presente invención proporciona, además, un método para obtener un reactivo para aumentar la recuperación de cobre en procesos de flotación de sulfuros de cobre que se caracteriza porque comprende los pasos de: cultivar en condiciones apropiadas células de microorganismos acidófilos que se seleccionan del conjunto formado por Acidithiobacillus sp, Leptospirilum ferriphilum y Acidiphillum sp, así como combinaciones de las mismas; y recuperar las células después de dicho cultivo. Por último, la presente invención proporciona un método para aumentar la recuperación de cobre en procesos de flotación de sulfuros de cobre que se caracteriza porque comprende añadir a un mineral de cobre un reactivo que comprende células de microorganismos acidófilos que se seleccionan del conjunto formado por Acidithiobacillus sp, Leptospirilum ferriphilum y Acidiphillum sp, así como combinaciones de las mismas.The present invention relates to the field of mining, in particular with processes involving microorganisms to obtain copper from minerals and provides a reagent to increase copper recovery in flotation processes of copper sulphides characterized in that it comprises cells of acidophilic microorganisms that are selected from the set consisting of Acidithiobacillus sp, Leptospirilum ferriphilum and Acidiphillum sp, as well as combinations thereof. The present invention also provides a method for obtaining a reagent to increase the recovery of copper in flotation processes of copper sulphides characterized in that it comprises the steps of: cultivating under appropriate conditions cells of acidophilic microorganisms that are selected from the set formed by Acidithiobacillus sp, Leptospirilum ferriphilum and Acidiphillum sp, as well as combinations thereof; and recover the cells after said culture. Finally, the present invention provides a method for increasing the recovery of copper in flotation processes of copper sulphides characterized in that it comprises adding a reagent to a copper ore comprising cells of acidophilic microorganisms that are selected from the set formed by Acidithiobacillus sp, Leptospirilum ferriphilum and Acidiphillum sp, as well as combinations thereof.
