Production Stripping Ratio
Stripping ratio is the ratio of the volume of waste rock stripped off to the volume of ore exploited during the process of surface mining. It indicates the volume of waste rock required to be stripped for mining per cubic ore.

Calculating Stripping Ratios for Area Strip Mines
Two major technical constraints involved in the determination of such schedule are: (i) the feasible combinations of ore and waste production (stripping ratio), and (ii) the ore production rate that meets the mill feed requirements. Optimization methods have long been used to improve mine design and life-of mine production schedules [1–12].
Improve lump/fines prediction by understanding porosity
An ore classification based on metallurgical properties is a powerful tool providing a common reference frame across mines/deposits. Ultimately, a better understanding of ore porosity enables better mine planning and scheduling decisions, improved prediction of crushing behaviour, as well as providing data which supports …

3.2.5: Instantaneous Stripping Ratio | GEOG 000
The Instantaneous Stripping Ratio (ISR) is the stripping ratio for a given push back, where a tiny slice of material, i.e., ore and/or waste, is removed from a pit wall. This section presents the ISR calculation for a steeply pitching deposit. Assume an idealized tabular and steeply pitching orebody that outcrops at the surface and dips to …
Mining 101: Strip ratio
The strip ratio is a critical metric, a shorthand for evaluating the potential return on investment in a mining project. It encapsulates in a single figure the estimated costs of extraction, which are inexorably tied to the market value of the ore. A high-grade deposit with a low strip ratio might attract investment, heralding robust returns ...

Newman iron ore mine Report | Wood Mackenzie
Newman is BHP's oldest and highest cost Pilbara operation. Contributing to its cost position is the higher average strip ratio of 2.7:1 and the longer average haul distances to crushers owing to the depth of the Mt Whaleback pit. Costs are expected to be lower in 2024 due to higher throughput and cooling inflation.

Surface Mining Techniques. Surface mining techniques include: open-pit mining, area strip mining, contour strip mining and hydraulic mining. Open-pit mining involves digging a large, terraced hole in the ground in order to remove a near-surface ore body (Figure (PageIndex{2})). This technique is used in copper ore mines in Arizona and Utah and …

Decarbonisation to drive dramatic increase in mining …
Together, grades and recovery rates determine the volume of tailings generated per unit of metal produced. Finally, predictions of future waste generation also require assumptions of the amount of waste rock produced per tonne of ore. This is called the waste rock-to-ore, or strip ratio (Nassar et al., 2022).
Surface Mining Techniques used in the Oil Sands
The strip ratio (SR) is the simplest measure of mining efficiency. Strip ratio is the fraction of overburden (or waste ore) versus the weight of bitumen-rich oil sands. A strip ratio of 2 is considered high but feasible if the ore grade is high enough. A better measure of mining economics is the TV:BIP ratio. TV:BIP is defined as the total ...
