Copper Production Calculation from Ore
This solution outlines the steps to calculate the daily copper production based on the provided ore supply, copper content, and extraction efficiency.
Step 1: Calculate Total Copper Content in Ore
Determine the total amount of copper available in the daily ore supply.
- Ore supplied daily: $10000$ tons
- Average copper content: $1.5\%$ by weight
- Total copper calculation: $ \text{Total Copper} = \text{Ore Supplied} \times \frac{\text{Copper Content}}{100} $ $ \text{Total Copper} = 10000 \text{ tons} \times \frac{1.5}{100} $ $ \text{Total Copper} = 150 \text{ tons} $
Therefore, the daily ore supply contains $150$ tons of copper.
Step 2: Calculate Actual Copper Production
Calculate the amount of copper extracted by the smelter, considering the extraction efficiency.
- Total copper available: $150$ tons
- Extraction efficiency: $80\%$
- Copper production calculation: $ \text{Copper Production} = \text{Total Copper} \times \frac{\text{Extraction Efficiency}}{100} $ $ \text{Copper Production} = 150 \text{ tons} \times \frac{80}{100} $ $ \text{Copper Production} = 120 \text{ tons} $
The smelter produces $120$ tons of copper per day.
Conclusion
The daily production of copper is calculated by first finding the total copper in the ore and then applying the extraction efficiency.
