Abstract:Mine solid waste and tailings pollution source analysis system is consist of total constituents in crude ore and solid waste, potential acid forming, extraction toxicity, water quality in tailings pond. Total constituents focus on heavy metal, such as Pb, Hg, Cd, Cr, As, etc. Potential acid forming assessment is on the basis of pH value experiment, acid-base account experiment（ABA）, net acid generation experiment（NAG）. Key element extraction toxicity assessment is selected according to total constituents data. Water quality assessment is conducted water from recycles pool below tailings dam. in order to guide mine enterprise, environment consultation unit and environment protecting management organization to conduct pollution source analysis.
