The silver content of ores from the Xinrong manganese deposit in western Guangdong is higher than 100×10-6on average. According to the electron probe analyses and other data,some conclusions have been reached as follows: The modes of occurrence of associated silver include minerals of stephanite,bromargyrite,Ag-Sb-tetrahedrite,electrum etc., which occur as small grains among or between Fe-Mn minerals. Slight amounts of silver exist in Fe_Mn minerals as adsorbed ions.
