Stripping ratio is the quantity of waste material that must be removed to extract a unit of ore. It is calculated by dividing the volume of waste material by the volume of ore. A higher stripping ratio indicates a larger amount of waste material that needs to be removed to access the desired ore.

Is the efficiency of a machine calculated by the ratio or by the product?
The efficiency of a machine is calculated by the ratio of useful output work to the input work, typically expressed as a percentage. This ratio helps determine how well a machine converts input energy into useful work output.
What is the ratio of kernel phenotype in this case?
Without specific details, it is impossible to determine the exact ratio of kernel phenotype. However, the ratio can be calculated by assessing the number of kernels with different phenotypes and then comparing them. Each phenotype's frequency divided by the total number of kernels will determine the ratio.
How does the experimental mole ratio compare with the theoretical mole ratio?
The experimental mole ratio is obtained from actual experimental data, while the theoretical mole ratio is calculated based on the balanced chemical equation. Comparing the two can reveal discrepancies and provide insight into the accuracy of the experimental results or any potential sources of error in the experiment.
In a distance-time graph the slope of is the ratio of time to distance?
The slope of a distance-time graph represents the speed of an object. It is calculated as the ratio of the change in distance to the change in time. A steeper slope indicates a faster speed.
How do you find the ratio of neutrons to protons?
The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).
How do you calculate the stripping ratio?
We divide the overburden thickness by ore thickness to get the stripping ratio For example if we have an overburden thickness of 80m and ore thickness of 50 m , then the stripping ratio will be: 80/50= 1.6
Is Ore to Overburden ratio and Stripping ratio are same?
Yes, a 3:1 stripping ratio means that mining one cubic meter of ore will require mining three cubic meters of waste rock.
What is break even stripping ratio?
the stripping ratio fot the last increment alomg the pit wall. it determines whether one should continue mining using open pit(surface) or switch to uderground.
How do you calculate stripping ratio for Open Pit Mines?
Overburden tons/ore tons
What is cost ratio calculated by?

Is a ratio the same as division?
No. A ratio is calculated using division but they are not the same thing.
What is The ratio at which two currencies are traded?
