摘要 |
<p>Methods for removing particulates from an aqueous suspension are provided. In at least one specific embodiment, the method can include mixing a polyamidoamine-epihalohydrin resin with an aqueous suspension comprising one or more first particulates to produce a treated mixture. An amount of the polyamidoamine-epihalohydrin resin in the treated mixture can be less than 500 g/tonne of the one or more first particulates. The method can also include recovering from the treated mixture a purified water having a reduced concentration of the one or more first particulates relative to the aqueous suspension, a purified first particulate product having a reduced concentration of water relative to the aqueous suspension, or both.</p> |
