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
How do you calculate stripping ratio for Open Pit Mines?
Overburden tons/ore tons
What is stripping Ratio and how is it calculated?
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.
What is the difference between overburden and ore?
Overburden refers to the rock or soil covering a mineral deposit, while ore is the mineral deposit itself that contains valuable minerals or metals. Overburden needs to be removed to access the ore for mining.
What waste rock must be removed before a mineral can be used?
Overburden and gangue are the waste rocks that must be removed before a mineral can be used. Overburden refers to the unconsolidated material above an ore deposit, while gangue is the unwanted rock in an ore deposit that has to be separated during processing.
What is lead distance?
It is the one sided distance traveled by a vehicle in a cycle of working. This term is used in mining for one sided distance traveled by the dumper in process of dumping of overburden (from the ore body to the dump) or dumping of ore(from the ore body to processing plant/stack yard).
In coal mining what is a good strip ratio?
1. Overburden O/B2. Coal / ore3. Interburden (or parting), I/B4. WasteSometimes:Waste = O/B + I/B(look at the context)Waste (O/B + I/B) needs to be removed to get access to coal / oreWhat Is Stripping Ratio ?a. Measures relative deposit depthQ: How important is depth in surface mining?* Consider Chuquicamata at 850 m depth, SR = 0.5* Consider Capital Quarries , Rolla, at 25 m depth, SR = 0.5b. To surface mine we need to remove some waste in addition to ore / coalc. SR measures how much waste needs to be removed so that a unit of ore/coal can be mined* This means "relative depth"source : coal-mining-info.co.cc
How is iron ore mined what type of mines open cut?
Iron ore is typically mined using open-cut mines, where large pits are dug into the ground to extract the ore. The process involves drilling, blasting, and removing overburden to expose the iron ore. The ore is then extracted and transported to processing plants for further refining.
What is the meaning of strip mining?
"Strip mining" is the practice of mining a seam of mineral by first removing a long strip of overlying soil and rock (the overburden). It is most commonly used to mine coal or tar sand.
How is bornite mined?
Bornite is typically mined using large-scale open pit mining methods. This involves removing overburden to expose the bornite ore, which is then extracted using explosives and heavy machinery. The ore is then processed to separate the bornite mineral from the surrounding rock and other minerals.
Why is open cast mining lead to waste heaps on the surface?
For an open cut, the overburden has to be removed so that the ore can be accessed. An underground mine needs a tunnel to be dug through the host rock until you reach the ore. In both cases, there is usually waste rock which also has to be removed from the mine so your machines can get to the ore once you have reached the ore body.
What is overburden?
Overburden is the layer of soil and rock that lies above a mineral deposit. It must be removed during mining operations to access the desired mineral resources underneath. This process can involve excavation, blasting, and other methods to clear the overlying material.
