Mining and RefiningBauxite Residue Management

It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components. Iron oxides (1030%), titanium dioxide (215%), silicon oxide (520%) and undissolved alumina (020%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite source.

Refining (metallurgy) WikiMili, The Free Encyclopedia

Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the
