Abstract
Ban Phuc Nickel Mine, Son La Province is one of the typical nickel sulfide mines in Vietnam. Solid waste dumps, ore dumps or tailings of mines can be sources of environmental pollution by generating acid mine drainage (AMD). Research methods in the field and in the laboratory show that Ban Phuc Nickel mine has mineral compositions of sulfides such as chalcopyrite, pyrotin, penlandite, ... so there is a potential for generating acid mine drainage (AMD) and dispersion of heavy metals into the environment. Research results on soil environment and surface water environment have shown that Ban Phuc Nickel mine has a low pH and high concentrations of metals (Cu, Ni, Fe, As, Cd).
