Silvassa and Tuticorin Refineries In the refineries at Silvassa and Tuticorin, which use IsaProcess TM technology, copper anodes are electrolytically refined to produce copper cathodes with a purity of 99.99% and slimes, which are treated further in a slimes treatment plant to recover additional copper. The residual slimes are sold to third parties. Copper cathodes are either sold to customers or sent to our copper rod plants. Silvassa and Tuticorin Copper Rod Plants In our copper rod plants, copper cathodes are first melted in a furnace and cast in a casting machine, and then extruded and passed through a cooling system that begins solidification of copper into 51x38 mm or 54x38 mm copper bars. The resulting copper bars are gradually stretched in a rolling mill to achieve the desired diameter. The rolled bar is then cooled and sprayed with a preservation agent and collected in a rod coil that is compacted and sent to customers. Doré Anode Plant In our doré anode plant, which was commissioned in February 2009, roasted anode slime is mixed with soda and borax and fed into a furnace known as the TROF converter. The TROF converter takes care of the smelting, reduction and refining steps in the same furnace, which saves energy when compared to a conventional furnace. After smelting, silver poor slag is poured off from the TROF converter and the doré metal is refined by blowing oxygen into the metal bath. Thereafter, the refined doré metal is cast into doré anodes each weighing 16.5 kilograms. Off-gases are led in a controlled way from the TROF converter into a bag filter and scrubber before being released into the atmosphere. Precious Metal Refinery In our precious metal refinery, doré anodes are refined into silver metal using an electrolytic process and further refined into gold metal by employing a leaching process, which uses concentrated hydrochloric acid, to remove gold metal from the gold mud produced during the electrolytic process. Platinum, palladium and other impurities, which are dissolved in the leaching process, are precipitated as concentrate. Delivery to Customers The copper cathodes, copper rods, phosphoric acid and other by-products are shipped for export or transported by road to customers in <strong>India</strong>. Doré anodes are shipped to Fujairah Gold FZE in the UAE.
