Gold Process Mineralogy - SGS
When the silver grade in an ore is high (>10 g/t) and/or the gold is present as so-called "küstelite" (Au<50%, Ag>50%) or electrum (Au 50-75%. Ag 25-50%), the processing may need to be modified. The greater reactivity of silver can influence the behavior of gold in flotation, leaching and/or recovery processes.
