The processing of high silica bauxites — Review of ...

2009-8-1 · 1. Introduction1.1.. ScopeThis document will critically review existing and potential processes for the processing of high silica bauxites. High silica bauxites are usually considered to be those with reactive silica contents in excess of ∼. 8% by weight of the bauxite (reactive silica is defined later in this paper).. This review is limited to bauxites as feedstocks for the processes.
