بيت /processing of bauxite ore
process, which involves the digestion of bauxite ore using concentrated sodium hydroxide at elevated temperatures and pressures [1, 3, 4]. The residue is a hazardous material due to its high alkalinity. Storage of the vast amount of residue remains (over 3 billion tonnes) an increasing problem [57]. Currently, a number of different appliions have been studied to reuse .

Bauxite ore is the leading source for aluminum. Bauxite is a hydrated aluminum oxide in the form of gibbsite, boehmite or diaspore that forms through surface weathering and direct chemical precipitation. Surface processes introduce a complexity and diversity of ore and impurity compositions that requires careful consideration of analytical technology when designing .

Bauxite is essentially a raw material that provides alumina, which on further processing provides the metal aluminum. So from an industrial point of view, it is more profitable if the raw bauxite ore is laden with aluminum and contains minimum impurities. And that is where bauxite and alumina testing comes into play. The testing is a method to effectively and accurately analyze the .

Most bauxite mines produce Direct Shipping Ore (DSO) bauxite as they require no processing before being sent to a refinery. However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and/or handleability. These deposits usually have a beneficiation plant that washes the bauxite and sends the high silica .
