Mixed collector compositions

摘要

Collector compositions and methods for making and using same are provided. The collector can include one or more etheramines and one or more amidoamines. A liquid suspension or slurry comprising one or more particulates can be contacted with the collector to produce a treated mixture. A product can be recovered from the treated mixture that includes a purified liquid having a reduced concentration of the particulates relative to the treated mixture, a purified particulate product having a reduced concentration of liquid relative to the treated mixture, or both.

1. A process for beneficiation of an iron-containing ore, comprising:
contacting an aqueous suspension or slurry comprising an ore with a collector to produce a treated mixture, wherein:
the ore comprises iron and silica,the collector comprises a mixture of an amidoamine and an etheramine,the amidoamine comprises a reaction product of a tall oil fatty acid and a polyamine,the polyamine comprises diethylenetriamine, 1,3-diaminopentane, or a mixture thereof, andthe mixture of the amidoamine and the etheramine has a weight ratio of the amidoamine to the etheramine of about 35:65 to about 65:35; and recovering a purified iron product from the treated mixture, wherein the purified iron product has a reduced concentration of the silica relative to the treated mixture.
