Flushing out: ATH is the feedstock material for
an array of water treatment chemicals such as
aluminium sulphate, a primary flocculent in
municipal and industrial water treatment operations.
Alumina trihydrate (ATH; aluminium hydroxide, or hydrated alumina) is the ultimate all-rounder; a feedstock material for aluminium production, but also the starting point for all non-metallurgical alumina grades on the market.
Well documented uses for ATH are in the production of smelter grade alumina for aluminium electrolysis, in addition to non-metallurgical grade alumina for calcined or tabular grades, but perhaps overlooked is the market for ATH in its own right as an industrial mineral derivative; either in commodity markets or speciality sectors.
Broadly speaking, the commodity market refers to ATH’s role as the starting point for an array of aluminium chemicals such as aluminium sulphate, used in water treatment while applications such as flame retardant fillers come under the umbrella of speciality markets. ...
