بیشترSulfur of Yulong is of magmatic origin. Increasing pyrite δ 34 S values from potassic to phyllic alteration stage is interpreted by disproportionation of SO 2 and subsequent sulfate reduction.. Pb isotopic compositions suggest that Pb of the Yulong deposit was sourced from both the ore-related porphyry and the Triassic wall-rocks.
بیشترThe oxide lead ore in a dolomitic matrix may contain clay slimes and a fairly large amount of pyrite and barite; both of these minerals have a negative effect on oxide lead flotation.
