The History, Challenges, and New Developments in the bauxite alumina treatment automatic filter press

May 19, 2016In the case of Burntisland, the bauxite residue needed to be transported on public roads through the town to a nearby old oil shale mine so a high solids content mud was a key requirement. In the mid 1960s at Ludwigshafen, vacuum drum filters were adopted. Figure 7 shows a typical press filter used for bauxite residue.The History, Challenges, and New Developments in the bauxite alumina treatment automatic filter pressMay 19, 2016In the case of Burntisland, the bauxite residue needed to be transported on public roads through the town to a nearby old oil shale mine so a high solids content mud was a key requirement.

Bauxite is a very practical absorbent used for regeneration of transformer and turbine oils. It is relatively inexpensive as natural bauxite because It contains a significant amount of alumina (70%). Bauxite is the raw material for the production of aluminum. Bauxite can be found in different colors from white to dark red.

In 2005, ALUMINIUM became a member of the MYTILINEOS Group and today is Europes most important vertically integrated alumina and aluminium production and trading plant.Alumina Filtration in the alumina production process bauxite alumina treatment automatic filter pressJun 18, 2010The production of alumina from bauxite is a hugely significant industry in its own right but it is also one of the most significant global users of filtration and separation technology. A typical alumina plant may use approximately 5001000m2 of filtration area per million tonnes of production (as well as many hundreds of square metres of gravity thickener/clarifier area).

What is the production of alumina?What is the production of alumina?Production of alumina has approximately doubled in the last 20 years to more than 80 million tonnes. A significant proportion of this increase came from squeezing more capacity out of existing plants, or adding additional streams to these plants.Alumina Filtration in the alumina production process - Filtration bauxite alumina treatment automatic filter press How much Alumina do plants use?How much Alumina do plants use?A typical alumina plant may use approximately 5001000m2 of filtration area per million tonnes of production (as well as many hundreds of square metres of gravity thickener/clarifier area).

However, it is important that the quantity of caustic in the mud is minimised and that the disposal area is sealed to prevent leaching of caustic soda into the surrounding soil.Alumina Filtration in the alumina production process - Filtration bauxite alumina treatment automatic filter press
