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 the overburden soil?
Overburden soil refers to the layer of soil and rock that sits above a mineral deposit or bedrock. It needs to be removed during mining or excavation activities to access the desired materials underneath. The overburden soil is usually of lower economic value compared to the underlying mineral deposits.
How do you remove overburden-soil for coal mining?
Overburden soil in coal mining is typically removed using large machinery such as draglines, shovels, or excavators. These machines scoop up and remove the soil to expose the coal seams underneath. The overburden is usually transported to a designated area for storage or backfilling.
What is the relationship between mineral ore and gangue?
Mineral ore is the valuable material that can be extracted and processed for its useful properties, while gangue is the unwanted material that is typically separated from the ore during the extraction process. Gangue does not have any economic value and is usually discarded as waste material. The relationship between mineral ore and gangue is that they are often found together in the same rock or ore deposit, with the goal of separating the valuable ore from the gangue to extract the desired minerals.
What is iron ore lumps and iron ore fines. What is the difference?
· Iron ore fines (less than 6mm) · Sized ore (size 5mm to 20mm) · Lump ore (size 10mm to 40mm) Iron ore fines are created as a result of mining, crushing and processing the larger pieces of ore. The reason lump is preferred is that when it is fed into a blast furnace for steel-making, its particle size allows oxygen or air to circulate around the raw materials and melt them efficiently. The fine iron ore products have first to be processed into what is called sinter, otherwise it will effectively smother the air flow in the blast furnace.
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?

What waste rock must be removed before a mineral can be used?

What is the difference between uranium hard and soft ore?
It is a difference between the hardness, generally expressed in the Mohs scale.
What is the difference between rock and ore?
Gems are valuable rocks aren't.
What is the difference between spoils and tailing?
The difference is the source of the material. Spoils come from overburden and is discarded as waste. Tailings come from left over dredging of stream beds that are discarded as as waste as well.
What is the difference between bauxite and aluminum?
Bauxite is the ore of aluminium, from which aluminium is is extracted.
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.
Difference between iron ore fines and iron ore pellets?
Iron Ore fines are Iron Ore that have been crushed to under 10mm. Iron Ore pellets are Iron Ore fines that have been concentrated and bonded together to form small balls, or pellets.
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).
