Chapter 4: Mining wasteThe ratio of waste rock/ore is called stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be removed to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often deposited in piles or heaps close to the mine to minimize transports. As waste rock is exposed to air and water, a ...
METHODS OF ORE RESERVE ESTIMATION_EXAMPLE · Stripping ratio simply refers to the amount of waste handled in order to recover certain amount of ore. It is mathematically expressed as the ratio of waste to ore. However a wide variety of units are used as well as indied below: Hence the maximum allowable stripping ratio at pit limit is given as: SR (Overall) = Volume of Waste/Volume of Ore For Example: Determine the Stripping Ratio .
Cutoff grade estimationFor the Breakeven (Mining) cutoff grade, mw = 0. Material below this grade should not be mined. These cutoff grades are the fastest way to classify ore and waste, however, in a more detailed analysis they should not be relied on. Lane's Method. Lane's Method was presented by Ken Lane in 1988 when he identified three distinct stages of cutoff grade appliion; mining, concentrating, and ...
