Surfactant compositions in alumina precipitation in the bayer process |
| abstract |
ABSTRACT The invention relates to a composition for use in a method of reducing the percent of small size alumina trihydrate crystals produced during crystallization of alumina trihydrate from a hot, caustic pregnant Bayer process liquor, the composi-tion comprising (A) a surfactant which will not degrade to anything less than a tall oil equivalent in the presence of a hot strong caustic solution, together with (B) an oil carrier or solvent vehicle for the surfactant that has a boiling point safely above that of hot Bayer green liquor undergoing precipitation. |
