Mineral Processing Plant Design
If it is practical to obtain representative ore samples, it is prudent to have testwork conducted to establish ore flow properties, which will influence design parameters. At virtually all mines, ore characteristics change over time, and it can be costly to "design in" the optimal flexibility required to …

Chapter 2. Production and Processing of Aluminum
The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.

Major Mines & Projects | Ramu Mine
The aluminium grade reduces with the increasing depth as it is a residual component in the weathering and leaching process. Nickel is apparently enriched in both saprolite and rocky saprolite, but cobalt is only enriched in the saprolite. The principal ore minerals identified in the Ramu deposit include goethite, asbolan and garnierite.
Bayer process - Wikipedia
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to ...
Mining and Refining – Process - World Aluminium
Mining and Refining – Process. The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to ...
Production process - European Aluminium
Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the so-called "bauxite residue", followed by a calcination step which removes the water content in the hydroxide.

ICMM & Operating mines
The processing method chosen to separate the mineral or metal resource from the ore depends on the type of minerals or the grade of the metal. The first part of the process is to reduce the size of the pieces of mined material. It might be crushed into pebble-sized pieces or ground into a fine powder.
