Figure 6 shows a trend graph of the moisture content of the bauxite ore over a period of 20 minutes. Such variations are virtually impossible to detect from stop-belt sampling of ore, but are easily detected by an on-line analyzer. Trend graphs, like in Figure 6, are useful to understand short-term variations of the moisture content of the ore.

Bauxite: The aluminum mineral bauxite information and pictures

Bauxite – Alufer Mining Limited

Bauxite is an aluminium ore found in deposits around the world. Once the ore is mined out of the ground, the red bauxite rock is crushed and dissolved into a white alumina powder, using what is known as the Bayer process. This alumina powder is then smelted into aluminium metal. Australia is the world's largest producers of bauxite.

Three-dimensional radar models are constructed by scanning the region along tightly-spaced profiles. The depth to bauxite and the thickness of bauxite is shown in real-time during surveying, allowing the survey to be adapted to ensure an accurate volume determination. The resultant profiles are processed and positioned using DGPS data.
