Abstract

This study aims: to determine the quality of waste Fe in the mining and settling pond inlet, determine the trend of Fe waste at the mine site, and to determine the trend of Fe waste in processing sites in 2018. The research was carried out by coming directly to the field and then taking samples of wastewater with a ballast bottle. Data analysis method by comparing with environmental quality standards. The results showed that the quality of Fe wastewater at mine sites 1 from January to September 2018 ranged from 0.27 mg/lt to 6.45 mg/lt still below the environmental quality standard. Mine Location 2 showed that Fe content is between 1, 72 mg/lt to 62.30 mg/lt, which is above the environmental quality standard in February of 34.14 mg/lt and March 62.30 mg/lt. Whereas in mine 3 showed is the Fe content is between 0.15 mg/lt to 27 mg/lt, the level of which is above the quality standard in January February and May 2018. Whereas at the processing location 1 results from an analysis of Fe content between 0.009 mg/lt to 3, 21 mg/lt is still below the environmental quality standard. Whereas in processing area 2 between 0.07 mg/lt to 3.16 mg/lt is still below the environmental quality standard. Evaluation of the trend in the level of Fe that is striking at mining locations 1 and 2 in March 2018. Whereas at mining site 3 in February 2018.
