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 balance.
