Pyrite, as well as being most important member of the disulfide group, is most abundant sulphide mineral in the earth and has been extensively studied. Once exposed to water and oxygen thru construction, mining and mineral processing operation, it could lead to chemical and biochemical oxidation with production of highly acidic, heavy metal leachates, which refer to acid rock drainage (ARD). This problem will lead to the biggest environmental pollution including underground watersource, land and flora and fauna. This study is to find the wayto treat the ARD problem by using organic material without harm the environment and cost is cheap. From the experiment, shown that the pH of the water after the reaction took part is very acidic and contains several hazardous heavy metal that are can give bad impact to human and environment. Calcium carbonate together with softwood and hardwood is used to prevent the ARD happen. These findings of the project will lead to solve the ARDproblemand introducingthe prototypeto further research. KEYWORDS: pyrite; pollution; acid rock drainage; organic material; calcium carbonate
