Methods and compositions for separating materials are provided. The present invention provides a method of separating a first material from a second material such as mixing the first material and the second material in a slurry with a beneficiation composition. The beneficiation composition can comprise methyl isobutyl carbinol mixture derived from a methyl isobutyl ketone and/or methyl isobutyl carbinol manufacturing process. Additionally air bubbles can be provided in the slurry to form bubble-particle aggregates with the first material and the bubble-particle aggregates can be allowed to be separated from the second material.
La présente invention concerne des procédés et compositions permettant de séparer des matériaux. La présente invention fournit un procédé permettant de séparer un premier matériau d'un second matériau tel que le fait de mélanger le premier matériau et le second matériau dans une suspension avec une composition d'enrichissement. La composition d'enrichissement peut contenir du mélange de méthylisobutylcarbinol provenant d'un processus de fabrication de méthylisobutylcétone et/ou de méthylisobutylcarbinol. En outre, des bulles d'air peuvent être contenues dans la suspension afin de former des agrégats bulles-particules avec le premier matériau, et les agrégats bulles-particules pouvant être séparés du second matériau.
