Prevention and mitigation efforts from acid mine drainage can be predicted by knowing the characteristics of rocks and looking for the direct contact of acid rocks with air and water. The static test aims to determine the potential for acid formation that occurs in rocks as a first step to characterize rocks. Tests were carried out on argillic silica alteration rock samples from the Lanut site, PT J-Resources Bolaang Mongondow. The calculation of total sulfur shows a smaller percentage of the value of the advance argillic than the silisic sample. The results of advance argillic samples, NAG pH> 4.5 were obtained and the value of Net Acid Producing Potential (NAPP) in the range of 110-153 kg H2SO4 / ton rocks which means that the potential nature of rocks cannot be ascertained PAF or NAF. Whereas for silisic alteration rock samples the pH value of NAG <4.5 and NAPP values in the range of 146 – 355 kg H2SO4/ton rocks means silisic alteration has the potential acid forming.[/vc_column_text][vc_empty_space][vc_separator css=".vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}"][vc_empty_space][megatron_heading title="Author keywords" size="size-sm" text_align="text-left"][vc_column_text]Acid mine drainage,Acid producing,Direct contact,Geochemical characteristic,High sulfidation,Rock sample,Static tests,Total sulfur[/vc_column_text][vc_empty_space][vc_separator css=".vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}"][vc_empty_space][megatron_heading title="Indexed keywords" size="size-sm" text_align="text-left"][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=".vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}"][vc_empty_space][megatron_heading title="Funding details" size="size-sm" text_align="text-left"][vc_column_text]This research/paper partially funded by PT LAPI ITB, Mining Environmental Laboratory CoRE Mining Environment and Mine Closure, and USAID through the SHERA program – Centre for Development of Sustainable Region (CDSR).
