The Nannihu ore field is largely represented by the Nannihu Mo-W deposit, Luotuoshan Zn-Cu-W deposit, and Lengshuibeigou Pb-Zn-Ag deposit. Mo-W mineralization at Nannihu occurs in the contact zone between the Nannihu intrusion and the wall rocks, showing typical characteristics of the porphyry-type deposit.

The following parameters were used based on which Zn, Cd and Pb plant biological content was determined: 1. Heavy metals content in individual parts of plants; 2. Bioaccumulation factor (BCF) - determines the metal uptake from the soil by plants, calculated as the quotient of the Zn, Cd and Pb content in the plant to the soil content [19,20]. 3.
Solid phase transformation and metal solubility were monitored after coprecipitation of Cd2+, Cu2+, Pb2+ and Zn2+ with Fe3+ to form ferrihydrite by titration to pH 6. The (co)precipitates were aged at room temperature for up to 200 d and subsequently heated for 60 d at 70 °C. The mode of (co)precipitate formation, rapid and slow titration, was also investigated. …
