FLOMIN™ CGM is a crystal growth modifier used in alumina and phosphate operations to control crystallization, reduce fine particle formation, and support more stable solid/liquid separation performance under variable conditions.
Product Overview
What is FLOMIN™ CGM designed for?
FLOMIN™ CGM is designed to influence nucleation and crystal growth to deliver crystal characteristics that support more stable separation behavior.
In alumina precipitation (Bayer process), gibbsite crystallization is a slow and sensitive step. Because the pregnant liquor contains organic and inorganic impurities, crystallization can be disrupted and fine particles can increase. CGMs are used to control crystal size and shape, limit unwanted nucleation, promote agglomeration of small particles into larger ones, and influence secondary nucleation—supporting improved precipitation performance, filtration, and product quality.
In wet-process phosphoric acid production, FLOMIN™ CGM is designed to act on phosphogypsum nucleation and crystal growth formed during digestion, in order to obtain a crystal structure more favorable to solid/liquid separation. This supports improved filtration behavior by strengthening drainage and wash efficiency, and by stabilizing filtration performance across changing operating conditions.

Application
Where / How FLOMIN™ CGM is typically used
Alumina (Bayer precipitation):
FLOMIN™ CGM is used in precipitation circuits to control gibbsite crystal formation in pregnant liquor, limiting fine “seed” formation, promoting agglomeration, and supporting more consistent particle size and precipitation performance.
Phosphate (wet-process phosphoric acid):
FLOMIN™ CGM is added in the digestion circuit, upstream of phosphogypsum filtration, to influence crystal nucleation and growth before solids reach the filters.
Implementation follows an application approach:
-
selection of the most effective addition location within the relevant circuit
-
alignment with operational objectives (capacity, stability, separation performance)
-
monitoring and adjustment to maintain consistent performance under changing conditions
