摘要： A family of amine mining collectors that uses alkoxylates allows for the easy adjustment of solubility and molecular weight useful because anionic and cationic mineral collectors require such varying degrees of solubility and molecular weight. The family of the present invention allows for the optimization of both parameters and an increase in collector efficiency.

摘要： A transportable modular system for enhanced minerals recovery from tailings lines and deposits, features two transportable mineral recovery modules (TMRM), each TMRM for transporting as a truck mounted module to a remote site as an independently-operable mineral recovery module, each TMRM to couple to another TMRM on-site at the remote site and used together to provide enhanced minerals recovery. One TMRM having a central engineered polymer mineral recovery module that receives tailings fluid having a mineral particle of interest, processes the tailings fluid using an engineered polymer configuration, and provides recovered mineral processing fluids having the mineral particle of interest and a tailings disposal fluid. One other TMRM is selected from a group of TMRMs that includes another central engineered polymer mineral recovery module, a tailings fluid management module, an additive/chemical treatment polymer management module, a tailings disposal module and a recovery mineral processing module.

摘要： Methods for purifying one or more value materials are provided. The method can include contacting an aqueous mixture comprising a value material and a contaminant with a dispersant and a depressant to produce a treated mixture. A weight ratio of the dispersant to the depressant can be from about 1:1 to about 30:1. The method can also include recovering a purified product comprising the value material from the treated mixture. The purified product can have a reduced concentration of the contaminant relative to the aqueous slurry.

For example, the method can comprise mixing the first material and the second material in a slurry with a beneficiation composition. The beneficiation composition can comprise one or more fatty acid by-products derived from a biodiesel manufacturing process or derived from transesterification reactions involving triglycerides. Air bubbles can be provided in the slurry to form bubble-particle aggregates with the first material and the bubble-particle aggregates can be separated from the second material.
