Description Presence of iron compounds as impurities in kaolin and feldspar, impart reddish colour to ceramic
products manufactured using these minerals. The quality of kaolin and feldspar was enriched mainly through
iron removal by biological methods. Bacteria isolated from kaolin of Indian origin were used for bioleaching.
Biotreatment of kaolin and feldspar using indigenous bacteria not only lowered the iron content of the minerals
but also improved their whiteness. The porcelain prepared with these biobeneficiated minerals was
compared to that prepared with non-beneficiated one. Physico-mechanical properties of porcelain were distinctly
improved by using biobeneficiated kaolin and feldspar, without affecting the individual mineralogical
compositions of kaolin and feldspar.
