From Tailings to Treasure? Miners Make Money Reprocessing

Now, some mining companies are figuring out ways to turn tailings to profits with novel reprocessing technologies to extract valuable metals from the waste. One example reported in Rapaport Magazine describes the efforts of De Beers Consolidated Mines (DBCM) to extract overlooked diamonds from 360 million tons of old tailings surrounding theget price

As mining techniques and the price of minerals improve, it is not unusual for tailings to be reprocessed using new methods, or more thoroughly with old methods, to recover additional minerals. Extensive tailings dumps of Kalgoorlie / Boulder in Western Australia were re-processed profitably in the 1990s by KalTails Mining. A machine called the PET4K Processing Plant has been used in a variety of countries for the past 20 yget price
