Esrey Resources Ltd. is focused on the extraction of zinc, lead and other metals from these waste materials in a hydrometallurgical process that is in the final stages of development. Its hydrometallurgical pilot plant, which is capable of processing approximately 100 tons of feed per annum, demonstrates the process is technically and economically viable. The plant is in operation and is being used to develop the Esrey hydrometallurgical process to process these hazardous feed materials and recover the value of the contained metal. It will also produce by-products suitable for sale or for environmentally responsible disposal. It has produced a Special High Grade London Metal Exchange (LME) grade zinc cathode from the plant. It is focused on the extraction of zinc and lead from primary Electric Arc Furnace waste and secondary waste materials from mines and furnaces in the Balkan region, which have created a substantial quantity of surface tailings, waste and by-product materials.
