As well known, cell surfaces and sulfide mineral surfaces are negatively charged, resulting in electrostatic......
elements (PGE), Cu, Zn, As, Se and Ba [3]. The main minerals of nickel in the metalliferous black shale in this area are vaesite and millerite. For molybdenum, the main mineral in the metalliferous black shale in this area is molybdenum sulfide [4-6]. The useful components of minerals are difficult to be treated by mineral processing and metallurgy technologies because such ores are low-grade multiple......
