When would a mineral no longer be an ore explain?
An ore is a rock that contains important minerals. An ore deposit must be profitable to mine. If it is no longer profitable, it is no longer an ore deposit.
What makes an ore deposit valuable?
Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.
What are the disadvantages of mining ore?
Disadvantages of Mining
- Mining can lead to soil pollution.
- Groundwater pollution.
- Deforestation.
- Depletion of natural resources.
- Mining implies the destruction of habitats.
- Endangerment of species.
- Loss of biodiversity.
- Landslides become more likely.
When deciding if an ore deposit will be mines a number of factors are considered some of these are listed below?
The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
What would have happened if there were no minerals?
But if we were to run out of a mineral — as in, exhaust our supply — it probably wouldn’t be because there’s none of it left on Earth. Even then, as mining technology advances, previously inaccessible minerals will become available and lower-producing ores will be processed more efficiently.
What will happen if there will be no mineral resources for us to collect and use?
Without mineral resources, industry would collapse and living standards would plummet. In 2010, the average person in the U.S. consumed more than16,000 pounds of mineral resources 1 (see Table Per Capita Consumption of Minerals). With an average life expectancy of 78 years, that translates to about1.
What are the most valuable ores?
The largest supply of this mineral was found in 2009 in South Africa and Russia, and its average price is $56 per gram.
- 8 – Diamond.
- 7 – Black Opal.
- 6 – Platinum.
- 5 – Gold.
- 4 – Rubies.
- 3 – Jadeite.
- 2 – Blue Garnet.
- 1 – Lithium.
Why should mining be stopped?
Mining activities increase the volume and rate of exposure of sulfur-containing rocks to air and water, creating sulfuric acid and dissolved iron. This acid run-off dissolves heavy metals such as copper, lead and mercury which leach into ground water aquifers and surface water sources, harming humans and wildlife.
Why we should stop mining in the Philippines?
Large-scale mining is destructive as it uses the method of open-pit mining which entails clearing thousands of hectares of rainforests and agricultural lands, deep excavations to extract minerals, the use of toxic heavy metals and chemicals to process mineral ores, and the consumption of millions of liters of water – …
What may cause a mineral deposit that had not been considered valuable to become highly sought after?
What might cause a mineral deposit that had not been considered an ore? If the economy changes or technology improves, a mineral deposit may be reclassified as an ore.
How does mining will affect the rock layers?
Answer: The change in overburden structure resulting from mining causes horizontal tension on the surface, while vertical shear occurs due to the movement of overburden in the vertical direction.
Which is part of an ore is not worth mining?
In most cases, an ore does not consist entirely of a single ore mineral but it is mixed with other valuable minerals and with unwanted or valueless rocks and minerals. The part of an ore that is not economically desirable and that can not be avoided in mining is known as gangue.
When do you get the ore out of the rock?
Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram:
How does the grade of an ore affect its value?
The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
What do you need to know about mining?
We must determine whether these concentrations are economically viable to mine. Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground.
