Orogenic gold ore sorting assessment based on geological
Gold from orogenic deposits represents one third of the world''s total gold production. Most orogenic gold ores contain significant amounts of barren waste rocks that are costly to process. The aim of this work was to evaluate the potential of sensor-based sorting (SBS) of quartz vein hosted orogenic gold ores. Jokisivu is an orogenic gold

Sulfur isotopes in sediment-hosted orogenic gold deposits
Because gold is believed to be mostly transported as bisulfide complexes in orogenic deposits (e.g., Groves et al., 2003; Goldfarb et al., 2005), the source of the sulfur is important to the understanding of the source of Au, the source of the hydrothermal fluids, and the genesis of the deposits.However, the S source of such deposits has been equivocal for many decades.
