"Hindustan Copper Limited invites sealed tenders in two parts for purchase of 3,500 metric tonnes of copper reverts - plus or minus 10 percent - of Khetri origin," a company notice said, adding that the metal could be purchased at the port of Kandla in the western state of Gujarat.
The tender closes on April 30 and bids will be opened the same day. A copper revert is the enamel of the red metal that solidifies and clings to the container during processing of copper and contains copper ranging from 20 to 40 percent and can be re-smelted to extract copper.
