Abstract
Described herein is a method of adding one or more boronic acid functional compounds to a mineral ore to result in a treated mineral ore. Where the mineral ore is a bauxite ore, and the ore is subsequently processed according to the Bayer process to obtain alumina, adding a boronic acid functional compound to the bauxite ore or a Bayer product followed by processing the treated bauxite ore or treated Bayer product using one or more processes associated with the Bayer process results in an increased yield of alumina product, increased alumina content (purity) in the alumina product obtained, or both when compared to the same bauxite ore or Bayer product subjected to the same process(es) but in the absence of a boronic acid functional compound.
