Industrial waste is considered one of the most harmful wastes and is produced in large volumes compared to any other. For example, in the coal-related energy industry, tons of gypsum and pyrite wastes are annually produced. Pyrite cinder is characterized as a waste material and poses potential environmental risk while having issues associated with disposal. Pyrite contains heavy metals such as arsenic, cobalt, copper, lead, nickel, and zinc. When pyrite waste is exposed to air and ground water or rain in impoundments, it readily oxidizes, forming large amounts of acid and releasing soluble toxic substances that pollute land and water sources.
That is why a lot of investigations and studies have been made to figure out how pyrite waste and pyrite cinder can be recycled or utilized. Currently there is only one consumer of pyrite cinders — cement industry, where ferrous components are used for creating binding calcium aluminoferrite during the clinker burning.
Angenium has found the solution. We propose a new way of recycling industrial waste, including pyrite cinders using a special sorbent with a help of which we can extract precious metals from it. We can expect not only recycling of them at storage facilities, but also their exporting. To find out more, go to www.angenium.io
