Gold Balance: Submicroscopic Gold Quantification

Gold recovery Submicroscopic gold is a major form of gold in many refractory ores particularly Carlin type ores and some epithermal gold ores SGS Minerals Services can quantify the presence of microscopic and submicroscopic gold in the various minerals in a sample using techniques such as QEMSCAN and combine this data to generate a gold.Ore is defined as “a naturally occurring mineral containing a valuable constituent (as metal) for which it is mined and worked” In other word ore is the most basic raw form of a mineral which requires additional processing for the valuable minerals (gold) to be removed.
