Question:
The percentage Fe and corresponding net value for an iron ore mine is given below Fe (%) Net value (INR per tonne) 58 4000 62 4500
Assuming net value versus grade curve to be a straight line, and mining cost of waste is INR 1000 /m3; the correct representation of stripping ratio, SR (m3/tonne) versus Fe (%) grade curve is
The percentage Fe and corresponding net value for an iron ore mine is given below
Assuming net value versus grade curve to be a straight line, and mining cost of waste is INR 1000 /m3; the correct representation of stripping ratio, SR (m3/tonne) versus Fe (%) grade curve is
| Fe (%) | Net value (INR per tonne) |
| 58 | 4000 |
| 62 | 4500 |

- SR= -3.250 + 0.125 x Fe
- SR = 3.250 +0.125 x Fe
- SR = 3250 + 125 × Fe
- SR = -3250 + 125 × Fe

Top Questions on Curves
- For the curve \( y(1 + x^2) = 2 - x \), if \(\frac{dy}{dx} = \frac{1}{A}\) at the point where the curve crosses the x-axis, then the value of \( A \) is:
- The area (in square units) enclosed between the curve $x^2 = 4y$ and the line $x = y$ is:
- The area (in square units) bounded by the curve y = |x−2| between x = 0, y = 0, and x = 5 is:
- A particle moves along the curve \(6x = y^3 + 2\). The points on the curve at which the \(x\) coordinate is changing 8 times as fast as \(y\) coordinate are:
