Technology development and testing for sustainable water management and additive raw material extraction at the pilot location Zinnerzgrube Ehrenfriedersdorf

Time span

From 01.04.2021 to 31.03.2024

Abbreviation

TERZinn

Project type

Sustainable Water Management

The objective of the TERZINN joint research project consists in the further development and on-site testing of processes for cleaning the water emerging from the Ehrenfriedersdorf tin ore mine, in particular with regard to arsenic. The aim is to ensure that there will be hardly any negative environmental impact in future, in order to make a contribution to the economic and social development of the region. In particular, it should also be demonstrated that the effects of mining on water quality can be avoided at reasonable costs by means of the most modern water treatment methods and an intelligent water management system, even for critical pollutants such as arsenic.

The main goals of the joint research project are the further development of efficient active and passive process approaches for the separation/fixation of pollutants as well as for the extraction of raw materials, the testing of a chemical in-situ immobilization of arsenic as well as further evaluation of the chemical stability of the immobilized material. Furthermore, extensive hydro-chemical monitoring is planned, on the basis of which systems for automated in-situ monitoring of the arsenic concentration in mine water and an AI-based control of the water treatment modules are to be developed. The technical objective is to adapt the procedures at the demonstrator level to the local conditions in such a way that a depletion of arsenic and other water pollutants can be achieved by up to 90%.
