Nickelhütte Aue GmbH

Nickelhütte Aue GmbH can look back on nearly 400 years of tradition as pyrometallurgical works and recycling company. The firm is speciallized in the recycling of waste materials containing non-ferrous metals. It is especially interested in Nickel, Copper, Cobalt, Vanadium, Molybdenum and precious metal containing spent catalysts from chemical and pharmaceutical industries but also from petrochemical industries and from hydrogenation processes of oils and fats. Several business divisions stand representative for the company's outstanding expertise in various fields, among others these are: pyrometallurgy, metall recycling, hydrometallurgy, catalyst recycling, corrosive solutions recycling, transformer utilization, metal trading and alloy smelting. In 2001, Nickelhütte Aue GmbH started to treat precious metals containing waste. The processing takes place in an installation disposing of special requirements due to the special treatment on behalf of all well-known precious metals producers. In 2002, Nickelhütte Aue GmbH expanded its processing spectrum to extend the production by vanadium compounds from NiV-containing filter dusts and -catalysts. The waste heat resulting from the pyrometallurgical processes is used to generate electricity and heat. With that the company is able to satisfy its own energy needs and supplies thermal energy also to other local companies.
