An Investigation of Digestion Methods for Trace Elements

The relative standard deviation (% RSD) for most elements was < 6%. The concentrations of trace elements in the ten bauxite RMs showed agreement with the limited certified (Li, V, Cr, Cu, Zn, Ga, Sr, Zr and Pb) and information values (Co, Ba, Ce and Hf) available. New trace element data for the ten RMs are provided, some of which for the first

Bauxite an overview ScienceDirect Topics

Bauxite ore is first mechanically pulverized and milled to reduce the particle size and then screened. The crushed ore is mixed with the process liquor containing caustic soda and processed in a grinding mill to produce a slurry containing 3540% solids.

Global mapping of Al, Cu, Fe, and Zn inuse stocks PNAS

Fig. 1. Linear regressions between inuse stocks and GDP for Cu (A), Zn (B), Al (C), and Fe (D).The correlations have an R 2 > 0.9 for copper and aluminium, whereas zinc and iron still retain an R 2 > 0.8. The small sample sizes, Fe (n = 7), Al (n = 8), and Zn (n = 6), may be of some concern, yet the correlation appears to hold when more studies are available, Cu (n = 18).

Why is Guinea Bauxite Considered the Best in the World

The large bauxite mines (>5 MTPA size) presently operating in the world are CBG, Guinea, Weipa, Gove, Darling Range in Australia, MRN Trombetas, Juruti Paragominas in Brazil and Panchpatmali in India. Except Guinea and Indian bauxite, most of the raw ore requires wet beneficiation process mainly to reduce the silica content.
