2013). Other process for upgrading crude bauxite ore is begun by primary crushing (crushed to 5 cm), followed by secondary crushing (crushed up to 10 mm highest) then washing and screening, and grinding. The crushed coarse sizes (3 mesh, 6 mesh, 8 mesh and 12 mesh) and ground powder sizes (100 mesh, 200 mesh and 325 mesh)
· Bauxite residue is a dark red thick muddy material with moisture content about 26% in its initial state. While bauxites are composed of well crystallized phases judging by the narrow peaks of XRD scans, the crystallinity of bauxite residue phases less developed as seen from the wider XRD peaks and therefore indiing to some XRDamorphous content ().
In bauxites, REEs also occur as authigenic phases,, phases that have been precipitated in situ within the bauxite profile from percolating fluids. Such phases are commonly REE fluorocarbonates of the bastnäsite (Ce(CO 3 )F) mineral group or phosphates of monazite group [ 25, 29 ].
This screen had a bearing and gear failure. We were tasked to work out why the machine failed, strip the mechanisms down and to measure all components to check if still within specifiions. After checking over all components, new parts were sourced. The screen was then reassembled in situ with new gears and bearings and is now running well.

Bauxite, AR (Almatis, Inc.) The Bauxite, AR facility was opened as a bauxite refinery in 1952. In 1954 and later in 1959, parts of Alcoa's chemical processes in East St. Louis, Illinois were transferred to the Bauxite facility. The facility acted as a combination chemical and refining plant until the Arkansas bauxite mines were shut down in 1990.
· Purpose. Bauxite residue is an alkaline, salinesodic byproduct of the Bayer process for alumina production. In situ remediation of bauxite residue is a costeffective management strategy that transforms the residue into a soillike medium; however, the effects of applied amendments on trajectories and progress of soil formation over the mediumlong term are unclear.
