Activated Carbon

Purity is essential in the production of pharmaceutical products. This applies to all stages, from raw materials to intermediates to final product. The unique properties of specific activated carbons provide superior removal of colour compounds, odour compounds, proteins and other contaminants that could be present in the raw materials, or that form during production.

Highly activated carbon is used in the dissolved gold recovery process, either by introducing it directly into the CIL (carbon-in-leach) tanks or into separate CIP (carbon-in-pulp) tanks after leaching.The activated carbon adsorbs the dissolved gold from the leach slurry thereby concentrating it onto a smaller mass of solids. The carbon is then separated from the slurry by screening and subjected to further treatment to recover the adsorbed gold.

Activated Carbons are extensively used in water treatment for removing free chlorine and / or organic compounds. Removal of organics from potable water could be to prevent common organic acids such as humic or fulvic from reacting with chlorine to form trihalomethanes (a class of known carcinogens) or, to treat wastewater to remove any number of organic compounds to make the water suitable for discharge.
