Sustainability In Small Scale Mining

Since the Rio Declaration on Environment and Development in 1992 in Rio de Janeiro and the publication of the agenda 21, the concept of Sustainable Development has become one of the major issues for governmental politics, societal developments and entrepreneurial policies. Current projects that deal with Sustainable Development in the mineral raw materials sector mainly focus on large-scale mining operations - especially for open pit mining - or on artisanal small scale mining. Artisanal small scale mining is in this connexion characterised as non-mechanized and mostly illegal mining activities. The number of workers is mostly far below 20. However, until now there exist no assessments or analyses with respect to the actual or potential contribution of industrial small scale mining to sustainable development. Industrial small scale mining refers to high technology or highly mechanized/automated extraction of small, high-grade deposits that due to their small size ? in combination with geological, depth and other constraints ? are not economically exploitable with large-scale mining operations. The Institute of Mining Engineering I and the Institute for Processing of Mineral Raw Materials at the RWTH Aachen University in Germany is currently conducting a research project financed by the German Research Foundation in order to investigate this issue. In the course of this project the sustainability of industrial small scale mining will be assessed. Therefore sustainability indicators, an assessment system and recommendations as well as options for actions and policies will be developed, in order to evaluate current industrial small scale mining activities as well as the potential for future developments in industrial small scale mining, both from a technological as well as from the point of view of sustainability, considering economical, social and environmental chances and risks.
