    Abstract: The invention provides methods and compositions for the addition of a CGM to precipitation liquor of a Bayer process. The CGM comprises a neopolyol, an ester derived from a neopolyol, and/or an ether derived from a neopolyol. Optionally the CGM may comprise water and/or an antifoaming agent and/or a hydrocarbon carrier liquid. The CGM is quite effective and results in a significant increase in mean particle size of produced alumina crystals.

    Abstract translation: 本发明提供了用于向拜耳法沉淀液中加入CGM的方法和组合物。 CGM包含neolyol,衍生自neolyol的酯和/或衍生自neolyol的醚。 任选地,CGM可以包含水和/或消泡剂和/或烃载体液体。 CGM是非常有效的,并且导致生产的氧化铝晶体的平均粒度的显着增加。
