concentration concentration or dressing of the ore

objectstorage.ap-mumbai-1.oraclecloud

Concentration is carried out by heating the powdered ore with a concentrated solution of NaOH at 473 — 523 K and 35 — 36 bar pressure. This process is called digestion. This way, A1203 is extracted out as sodium aluminate. The impurity, Si02 too dissolves forming sodium silicate. Other impurities are left behind.

Metallurgy - Purification of ores

The ore is generally associated with rock impurities like clay, sand etc. called ' gangue or matrix'. The purification of ore means removal of gangue from the powdered ore. This process is otherwise called concentration of the ore or ore dressing. Thus, the percentage of the ore in the concentrated ore is higher than that in the original ore.
