Bayer Process Plants | Noranda Alumina

A Bayer process plant is principally a device for heating and cooling a large recirculating stream of sodium hydroxide solution through a temperature range of up to 500oF per cycle. Liquor flow rates of 5,000 to 10,000 gpm are common in the newer plants. Bauxite is added at the high temperature point, red mud is separated at an intermediate temperature, and alumina is precipitated at the low ...

What Is the Bayer Process?

What Is the Bayer Process?

The Bayer process is a chemical process widely used in the industry to produce alumina from bauxite. Invented by Austrian engineer Karl Joseph Bayer in 1887, the basic principle is to convert aluminum hydroxide to sodium aluminate with concentrated sodium hydroxide solution, and to reprecipitate aluminum hydroxide by diluting and adding aluminum hydroxide seeds. The sodium hydroxide solution ...

The Aluminum Manufacturing Process

The Aluminum Manufacturing Process

The Bayer Process. Aluminum manufacturing begins with bauxite, an ore that consists of aluminum oxide, iron, and other metals. As soon as the bauxite is mined, it's subjected to the Bayer process—a method named in honor of the Austrian chemist who developed it in the late nineteenth century. Since aluminum oxide must be separated from any surrounding impurities before it can be processed ...

During alumina production, sodium aluminosilie scale formation in process pipes, vessels, and equipment is a major problem. The two most common forms of scale are sodalite and cancrinite. This study was undertaken to gain greater understanding of the scaling process, in particular the mechanisms, supersaturation, and kinetics of the desiliion reactions, which lead to scale precipitation.
