Cyanide Process For Extraction Of Gold

Cyanides 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 partially due to cyanide modern mines are much larger than before cyanide was used.
