摘要
After the sample is ignited in 650℃ and cold digested in aqua regia （1＋1）,gold is enriched by foamed plastics and is released by thiourea solution.The gold in the sample ore is measured by flame atomic absorption spectroscopy.This method is suit for measurement of gold in rock minerals which contains more than 0.05×10-6 gold.
