Surface and bulk activation of a siliceous bauxite during attrition milling
In SMILE, leaching is carried out while milling is in progress; the commonly used dispersing media (in wet milling operation), water is replaced with the leachate, NaOH solution in the present study. 100 g of bauxite (d 50 = 17 μm) was subjected to SMILE in an attrition mill using 250 g/l of Na 2 O as leachate cum dispersant at 90 °C for aAs part of its operations, Australian Bauxite is developing a proprietary technology called TasTech that will enable the company to easily separate its bauxite stockpiles into three products: high-grade, metallurgical bauxite (>45% Al 2 O 3); cement-grade bauxite; and bauxite for fertiliser and other products.

A bauxite residue typically contains 15–25% of alumina depending on the origin of its ore and process conditions. A laboratory-scale investigation of the effect of milling operation andBauxite can be found in a number of different physical forms including: pisolitic, friable and hardcap. Each bauxite will have its own distinctive crushing and milling characteristics. Bauxite can be highly variable through the mine pit profile, both vertically and horizontally.

Bauxite grindability at elevated temperature in various mills
The present paper deals with the grindability experimental results of an Australian bauxite sample in the Universal Hardgrove mill, the Universal Bond ball mill and the heat insulated Bond Rod Mill in the temperature range from 20 up to 80 °C.As previously observed the grindability of the bauxite has improved at elevated temperature.the ball mill half filled with the grinding media of one inch steel balls counting 100 in number. The open end of the mill was closed by clamping the lid tightly to the mill so that no leakage of the material takes place during grinding operation. Then the mill was run for a period of 3 min. and the reading of energy meter was noted.Studies on Batch Grinding of Bauxite Ore in Ball Mill

Major Mines & Projects Weipa Operation
Summary: Weipa operations includes three bauxite mines East Weipa, Andoom and Amrun. Bauxite ore in Weipa is found in a layer three to four metres deep in the form of small, red pebbles, called pisolites. Vegetation is removed from the site to be mined and scrapers strip the topsoil (which varies in depth from one to ten metres).It includes the steps of bauxite milling, pre‐desilication, digestion, cooling, clarification, washing and disposal of residues. Looking at the practise of tailing storage of other mining operations, Azam and Li125 found a staggering average global failure rate of 2.2 dams per year over the last hundred years.
