Regulating Catastrophic Risks by Standards
© Lexxion Verlagsgesellschaft mbH (2/2011)
This article analyses the role played by standards of protection in the regulation of catastrophic risks. It examines how to protect people against the occurrence of catastrophic events, considering that the related risk is highly uncertain and difficult to predict using rational methodologies. In this perspective, the article focuses on environmental risks and terrorist threats affecting common goods – namely environment and security – areas where any damage is susceptible to producing ruinous effects and huge casualties.

Environmental Impacts at a Gold Mining Enterprise in Bolivia
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2008)
EMIRSA has used NaCN as leaching agent from the beginning at the Kori Kollo gold mine and does so until today. During the project of oxidised ores (1982–1992) heap leaching and subsequently the Merrill-Crowe-Process (precipitation with zinc dust) were applied, gaining a gold precipitate as product. The metallurgical process was changed with the mining of sulphide ores (1992–2003) in favour of leaching in agitated tanks including CIL (carbon-in-leach), followed by electrolysis and casting of bars of doré (an alloy of gold and silver).
