Bauxite washing for the removal of clay | Request PDF. Therefore, bauxite is processed and washed in trommels to disintegrate and remove the clay before sending the ore as a feed to the Bayer process Estimation of ore washing potential and the .
Bauxite washing is a physical process that causes the disintegration and deagglomeration of the clay matrix, and bauxite is liberated from the clay (mainly rich in silica).
Abstract Clay impurities associated with bauxite negatively affect the Bayer process for alumina production. These impurities should be removed as far as possible by a beneficiation technique before the ore is used as feed for the Bayer process. In this current investigation, bauxite washing was conducted in the laboratory.
Bauxite washing for the removal of clay | Request PDF. mad et al (2014) washed the bauxite ore for the removal of clay using various techniques and showed that the bauxite washing is the function of material retention time inside the washing drums.
Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.
