Is this Pahang kampung getting sick from gold mining? We

The safe amount of cyanide accepted is 100-500 parts per million. In Malaysia, the standard is 4.7 parts per million, so it sounds like we’re quite far from the limit. It’s been proven to be SAFER than the alternative which is liquid mercury (previously the main method to extract gold). This is so because cyanide solutions degrade quickly in sunlight.

The Metallurgy of Cyanide Gold Leaching An Introduction

Oct 20, 2014 Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Preg-robbing gold ores ScienceDirect

Jan 01, 2005 Preg-robbing is an important phenomenon that inhibits gold recovery due to the presence of naturally occurring carbonaceous matter. In case of certain ores, gold recovery by cyanidation is limited by the presence of naturally occurring carbonaceous material that adsorbs gold from alkaline cyanide solution unless steps are taken to prevent this adsorption reaction from occurring.
