6- Complete the Table below, assuming a profit allowance of $3.00 per tonne. Then, assuming a stripping cost of $2.00 per tonne of waste and a copper price of $3.63 Ab. calculate the economic stripping ratio (SR₂) for each of the copper head grades. Also, calculate the cutoff grade for copper prices of $3.40/ lb and $2.10/ Ib. Show your calculations. -- Note: Head grade is a general term referring to the grade of ore delivered to the processing plant. Since the broken ore comes from various sections of a mine, the ore accepted at the Mill/Processing plant consists of a blend of various ore grades. Therefore, the term head grade or simply head is commonly used in the plural forme. head grades or heads.
