dengang, midt i 1990'erne, overvejede vi, hvordan de anvendte kemiske stoffer påvirkede miljøet, og at brugen af cyanid indebærer behandling af enorme mængder malm. derudover var der ikke kun de skadelige virkninger ved cyanidet, men også ved de stoffer, der bruges til fjernelse af cyanidet, nemlig klor og kalciumoxid.
at that time, in the mid-1990s, we considered the environmental impact of the chemical substances used and the fact that cyanidation involves processing huge volumes of ore, in addition to which there were the harmful effects not only of the cyanide but also of the substances used for so-called de-cyanidation, which are chlorine and calcium oxide.
