Fe metal =15 mmol/L Cu metal= 10 mmol/L Acid 2.5 =mmol/L Figure 1 Mine geographical setting Based on the data provided by the mining client, it is likely that if no remediation action is put in place, 10% of Fe and 15% of Cu from the mine tailing/acid mine drainage is estimated to be discharged to the lake per day. Average streamflow at the outlet of the lake is measured to be 5 x 103 L/day. A percentage of each metal concentration released from the mine tail/ acid mine drainage to the lake and the transportation pathway of the metals (sinks/deposits in the lake, released out of the lake; goes undetected) is as described in table 2: Table 2 Transportation pathway of metals discharged to the lake Transport of metals discharged to the lake Fe Cu Sinks/deposits in the lake = Fe50% Cu 60% Released out of the lake = Fe 35% Cu 30% Losses/undetected = Fe 15% Cu 10% If a volume of 0.01 L/day mine tail is discharged to the lake, calculate the mass (mg) of Fe and Cu metal that sinks/deposits in the lake per day (MW of Fe= 55.8 g/mol; Cu= 63.5 g/mol). (Include the details of the working steps of the calculation)
