In the Glossary of Open Pit Mining terms (appended below) we explain the concept of strip ratio, and how higher gold prices should allow an operation to sustain larger strip ratio and thus access deeper parts of the ore body.
CHAPTER 8 Stripping Ratios, Pit Limits Cutoff Grade Optimization Dr. Teuku Andika R Putra USM 2014 Stripping Ratios The stripping ratio (SR) refers to the amount of waste that must be removed for a given quantity of ore in open pit mining.
In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore. For example, a 31 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock.
Nov 05, 20180183;32;Stripping ratio is a term that is derived from the mining industry and is used in reference to the open pit mining process. The stripping ratio method of calculating the profitability of the mining procedure is commonly used in the ore or coal mining process. In relation to its application in the mining of ore, the utility of the stripping
Apr 27, 20130183;32;Minas Rio Iron Ore Project, Rio de Janeiro Mining Technology. The Minas Rio iron ore mining project is situated in the states of Minas Gerais and Rio The initial run of mine (ROM) ore will be 56mtpa with a strip ratio of . 187;More detailed
In coal mining Choosing a mining method calculated with the aid of stripping ratios, which represent the amount of waste material that must be removed to extract a given amount of coal.
* Consider Capital Quarries , Rolla, at 25 m depth, SR = 0.5 b. To surface mine we need to remove some waste in addition to ore / coal c. SR measures how much waste needs to be removed so that a
SURFACE MINING METHODS Blogs Strip mining is ideally applied where the surface of the ground and the ore body itself are , of strips Typical examples of this type of mining are the larger tonnage coal , 52 Discuss the concept of stripping ratio and how ,
In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore.. For example, a 31 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock
You would also find either strip ratio or the waste mined (tonnes) in here as well. Waste mined is outside the scope of this tutorial, but you should know that it is a big driver for mining costs such as haulage and drill blast.
Flat is good. Less than a 21 strip ratio, which is an excellent ratio of overburden (waste material) to ore. This mine has some of the most desirable economics on the planet for a bulk tonnage mine.)
The parameter known as the stripping ratio is almost universally used and represents the amount of uneconomic material that must be removed to uncover one unit of ore. Fig. 126.96.36.199 represents an idealized open pit ore body, dipping at angle a. 1.1. 13. Overall stripping ratio representation .Stripping Ratio Considerations y Fig.4..

The clean coal stripping ratio is more indicative of a mine's performance as it In coal mining what is a good strip ratio Wiki Answers What Is Stripping Ratio? a. Measures relative deposit depth. Q How important is The boundary stripping ratio in ore mining Springer Industrial Scientific Research and Planning Institute, Moscow
strip ratio in coal mining break even stripping ratio example for coal mining , The clean coal stripping ratio is more indicative of a mine, Break even stripping ratio, In mining, stripping ratio or strip ratio refers to the ratio.
Aug 03, 20110183;32;This value is the stripping ratio at which the costs of mining and processing the ore and stripping the waste are equal to the revenue from the ore. They determine the amount of economically recoverable ore.9. volume of waste to be excavated and moved.

The strip ratio (SR) is the simplest measure of mining efficiency. Defined as the weight of overburden (or waste ore) divided by the weight of oil sands ore, 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 TVBIP ratio.
The DFS supports an initial 11 year mine life, producing ~100,000oz per year and delivering strong margins. It confirmed a 2.5Mtpa processing rate, low strip ratio of 3.5 and noted the good access to established power and transport infrastructure.
The reduced strip ratio of 0.55 to 1 is low in iron ore mining industry terms. This has always been a distinct advantage of the Agbaja iron ore project, it has now been defined and recognised in the mining
This handbook on surface strip coal mining serves as a general introduction to the subject of mining, specifically surface strip coal mining. It is intended as handbook for engineers who are new to the field of mining engineering, or for students who are entering the field with little prior knowledge.
Fortescue strip ratio reduction something of a magic pudding there was a reversion to the much higher waste to ore ratio in years to come as life of mine planning dictates. the strip ratio
Strip ratio in iron ore Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size reduction requirements including, Strip ratio in iron ore, quarry, aggregate, and different kinds of minerals.
In mining, stripping ratio or strip ratio refers to the ratio of Increasing strip ratio has a very significant effect on mine economics Strip Ratio Variables A number of factors Ratio of stripping to ore .
To surface mine we need to remove some waste in addition to ore / coal c. SR measures how much waste needs to be removed so that a unit of ore/coal can be mined * This means quot;relative depth
reflecting reserves that account for the lesser mining selectivity more ore at a lower grade and lower strip ratio. Based on the 2018 performance this reduces the grade by 21%.
While these figures may be a good starting point in early stages of mining studies, it does not take in to consideration the complexity of the problem. Dilution factor varies within a single mine for different benches and zones. This is due to changes we see in grade distribution and shape of ore body.
It is BHP Billiton's lowest cost iron ore mine owing to its very low strip ratio and relatively easy mining conditions. However, it produces a low grade fines product so the low mining cost is somewhat offset by the discounted price it receives.
