The tailings, which are small in particle size and exposed to natural environment, especially the extremely tiny weathered secondary mineral kernel, can easily react with air, water and living things. Up to now, the reactive tailings have caused a series of environmental problems for water and soil. In this paper, physical and chemical properties of the sulfide ore tailings were analysed. Leaching experiments in laboratory were carried out and the results showed that acidic condition can accelerate the oxidation and dissolution processes of the sulfide tailings, lead to more surounding releasion and migration of heavy metals from the tailings reservoir.
