M Management of acid mine drainage (AAT) is the duty and responsibility of the company, there are many systems and methods for managing acid mine drainage. One of the efforts to manage AAT is geochemical analysis based on kinetic, metallic and mineralogical tests. The kinetic test uses the Free Draining Column Leach Test method with measurement parameters namely pH, TDS and EC. The results of pH measurements on rock samples BL-A1 and BL-A2 are acidic, while samples BL-B, BL-C, BL-D, BL-E, BL-F are not acidic. The results of measuring the TDS and EC values of BL-A1 and BL-A2 have TDS values (>500) and EC (>1000) while rock samples BL-B, BL-C, BL-D, BL-E, BL-F have values TDS (<500) and EC (<1000). In the metal test, it was found that the iron metal content in all samples was below the quality standard, while for the heavy metal content manganese it was found that only samples BL-A1 and BL-A2 had manganese metal content that was above the quality standard. Meanwhile, mineralogical tests using XRD on samples BL-B, BL-C, BL-D, BL-F showed that the most dominant mineral in the four samples was silica mineral. Based on the kinetic test results along with supporting data from metal tests and mineralogical tests, the geochemical characterization of BL-A1 and BL-A2 is classified as PAF and BL-B, BL-C, BL-D, BL-E, BL-F are classified as NAF.
