Cyanide Use in Gold Mining Earthworks

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold

The cyanide revolution: Efficiency gains and exclusion in

1. Introduction. In recent decades, gold mining expanded from its historical core (South Africa, the United States, Canada, Australia, and Russia) into a wide range of new gold mining regions, many of them located in the global South (Verbrugge and Geenen, 2020).In addition to the expansion of large-scale industrial mining, many of these regions have witnessed a notable increase in artisanal

Comparative methods for predicting cyanide pollution in

2020-5-13  It has been reported that persistent cyanide pollution occurs in artisanal small-scale gold mining (ASGM) catchment areas in Burkina Faso. In the present study, logistic regression (LR) and Regression Kriging (RK) methods were applied to predict cyanide pollution hazard at the catchment level as well as to determine the most vulnerable areas to prioritize for restoration of degraded ecosystems.
