Abstract
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.
