Citric acid concentration is the main significant factor of H2 SO 4 with CA leaching, suggesting that citric acid can be used as an effective reducing agent for iron removal from kaolin clay. For sulfuric acid leaching, % IEY was achieved at 90 °C after 180 min of leaching at 20% pulp density, and 3 M H 2 SO 4 concentration.
Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the chemical composition Al 2 Si 2 O 5 is a layered silicate mineral, with one tetredral sheet of silica (SiO 4) linked through oxygen atoms to one octedral sheet of alumina (AlO 6) octedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.

Kaolin, also called china clay, soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other products. Kaolin is named after the hill in China (Kaoling) from which it was mined for centuries. Samples of kaolin were first sent to Europe by a French Jesuit missionary around 1700 as examples of ...
Calcium and iron removal from a bauxite ore by Bacillus polymyxa was demonstrated. Within a period of 7 days, the above organism could remove all the calcium and about 45 % of iron from the ore in the presence of 2 wt.% sucrose in a Bromfield medium [4]. Berthelin et al. [5] have described the important role of bacteria in iron reduction when ...
