The Speciation Characteristics of Heavy Metals and Composition of Sediments in Lanjian Mine of Panzhihua

In this study, nine samples were collected along the trenches of LANJIAN mine and its water system in order to study the effect of Panzhihua Vanadium Titano-Magnetite on water during mining. Particle sizes of the sediments were analyzed with the laser, mineral composition of the sediments were analyzed with the X-ray diffraction analyzer, the content of CuPbZnHgCdAsCrCoNiMnVTiFe and the Speciation characteristics of part of them were analyzed with the atomic absorption spectrophotometer and ICP-MS. These provide a reference for the environmental governance of mine.
