ASSIGNMENT
Question 1: Name and explain five surface mining methods.
Question 2: Explain 5 factors that influence the choice of a surface mining method.
Question 3: Explain with the aid of diagrams how hydrothermal and magmatic deposits are formed.
Question 4: Differentiate between placer and alluvial deposits.
Question 5: Differentiate between skarn, VMS, SEDEX and Carlin-Type deposits
Question 6: Explain the term stripping ratio.
Question 7: How does stripping ratio affect the economic viability of a mining project.
Question 8: A mining project has a stripping ratio of 12:1 (12 cubic meters of overburden to 1 cubic meter of ore). The cost of removing overburden is $8 per cubic meter. Calculate the cost of overburden removal per cubic meter of ore.
Question 9: A mining project has a stripping ratio of 10:1. The commodity price is $40 per ton, the mining cost is $20 per ton, and the cost of removing overburden is $15 per ton. Calculate the profit per ton of ore. Based on this information, explain why mining might not be economical.
Question 10: Two potential ore deposits are being assessed. Deposit X has a stripping ratio of 3:1, and deposit Y has a stripping ratio of 8:1. Both deposits have a commodity price of $60 per ton, a mining cost of $25 per ton, and an overburden removal cost of $10 per ton. Calculate the profit per ton for each deposit and discuss why deposit Y might not be economically viable.
