    摘要: The invention provides a novel process for improving the recovery of precious metals from recalcitrant refractory ores by the use of hydrofluoric acid dissolved in ionic liquids. The solution of hydrogen fluoride gas in an ionic liquid is contacted with dry crushed ore at a temperature and for a period of time commensurate with the fracturing of a specific recalcitrant refractory ore. The excess ionic liquid is separated from the ore and the fractured ore is further treated with dilute sodium cyanide solution to extract precious metals in greater yields.
