Abstract:
The copper ore flotation conducted by PT XYZ produces copper, and other metal concentrates as tailings. The copper concentrate will then be processed as industrial raw material, while the tailing waste is dumping a waste dump. The copper ore flotation tailings must follow the tailings waste management rules. Monitoring tailings quality testing must be done, which includes physical and chemical parameters. The results of the analysis of copper ore flotation tailings are comparing with the provisions issued by the Ministry of Environment No. 92 of 2011. And 382 in 2016. Furthermore, to monitor the state of seawater around the mining site, water quality testing is divided into three zones, Zone A with into> 120 m, Zone B 0 - 120, and Zone C (tailings free). Seawater quality monitoring is carrying out in zone B. The quality test results tailing flotation Copper ores how physical and chemical parameters are below the threshold set by the Ministry of Environment. Whereas monitoring of seawater quality carried out in zone B, TDS exceeds the intensity at S15B, while dissolved metal concentrations are below the threshold at all stations.
