Foundry Work

Process of making a metal casting of an object By pouring molten metal into a mould. Mould is made using a pattern of the article required

Production of Potassium Carbonate

From KOH, Potassium Carbonate (k2Co3) is produced using Liquid Co2. Since the purity of Liquid Co2 used is very high, k2Co3 produced would have the highest purity fetching more price.

Similarly, Barium Carbonate can also be produced using Co2 by non-thermal process from barite by means of mechano-chemical treatment.
