500% Increase — Plasma Pre-treatment Dramatically Increases Detectable Au/Ag/PGM Content in Refractory Ore — Technical Summary of Analytical Results
Abstract A set of post-treatment samples from a plasma-based pre-treatment process were analysed for gold, silver and platinum-group metals (PGMs). Standard laboratory digestion and atomic absorption analysis showed marked increases in detectable precious metals in plasma-treated material versus untreated fractions. Quality control results were within accepted limits. Findings indicate the plasma process can liberate precious…

Comprehensive Report on Amorphous Gold
Origins and Formation Amorphous gold is a distinctive form of gold mineralisation characterised by the presence of nanoscale gold particles that lack a well-defined crystalline structure. These particles exist in a disordered, non-crystalline, or colloidal state, often associated with amorphous silica gels or carbon-rich phases. Amorphous gold primarily forms in orogenic (lode) gold deposits and…

Recovering the Un-Recoverable – Nanogold™ – Refractory Entrapped Gold
Geologists often face significant challenges when it comes to the recovery of gold from refractory ores. These ores, which contain gold particles locked within sulphide minerals or organic carbon, typically yield lower recovery rates using traditional methods like cyanidation. While existing technologies such as roasting, bio leaching, and pressure oxidation have improved recovery rates to…
