Marble mining and quarrying exist in Biak-na-Bato because the area is rich in marble deposits, making it a viable industry for economic development. The quality of the marble found in the area also contributes to its desirability for extraction and processing. Additionally, the presence of established infrastructure and expertise in marble mining further supports the industry's presence in Biak-na-Bato.

Where does gold exist?
Gold is found in the Earth's crust, primarily in quartz veins and alluvial deposits. It is often extracted through mining techniques such as open-pit mining, underground mining, and placer mining. Gold can also be found in small quantities in seawater and some meteorites.
Why marble is a impure substance?
Marble is considered an impure substance because it is composed of various minerals such as calcite, dolomite, and aragonite. These minerals can vary in their composition and can contain impurities like clay, sand, or other minerals, making marble a heterogeneous material.
How does marble differ from limestone there than color?
Hardness, Elasticity, Porosity, Permeability, Density, resistance to diagenesis, conditions of formation. Generalities (this means that in general the following are true and rules don't follow the exception if any exist) Hardness: marble is harder than limestone. It has a higher compressive strength and cohesion. This can get much more technical so let's leave it at that. Elasticity: Young's Modulus, shear modulus of marble is higher. Bulk modulus and poisson's ratio of marble is lower. Porosity of marble is lower. Permeability of marble is lower. Density of marble is higher. Limestone is often altered via fluids and chemical underground and marble isn't. Marble is metamorphic rock and limestone in sedimentary. Marble and Limestone are spelled different.
Can you find uranium in the Philippines?
Uranium has not been found in significant commercial quantities in the Philippines. The country has limited known uranium resources, with exploration and mining activities focused on other minerals such as gold, copper, and nickel.
Is there uranium in Sri Lanka?
Sri Lanka has reserves of thorium; uranium exist also (as a component of monazites; not important reserves) but is not extracted now.
Is there mining in Hawaii?
Yes, primarily surface mining of basalt rock to make crushed stone (for concrete, asphalt paving, and termite barriers) as well as mining of lava rock for landscaping. There is no coal, metal, or major mineral mining in Hawaii.
Why is marble useful for carving chess pieces?
It's not whether it's useful or not. Marble Chess pieces exist (~$150 or greater).
Are there any mining helmets in minecraft?
There are no helmets made specifically for Mining, but normal Helmets do exist in Minecraft.
How much does a large marble weigh?
Marble is a type of rock and it exist in nature as a mountain or hill. There is no size limit for this answer. It can weight a few kg for construction marble cut to a few Gigaton of mountain rock.
Why does mining exist?
To supply people and industries with minerals, metal ores and coal, etc.
Why aren't quarries dug everywhere in the UK?
Because not all areas have raw materials suitable for quarrying ! Many minerals exist in 'pockets' - some of which are confined to small areas.
Is uranium found in Greenland?
Yes, uranium exist in Greenland and is prospected now by an Australian mining company.
If there was no mining would the gold rush exist?
The gold rushes existed because gold was first found on the surface. Much of the gold was extracted by panning . Actual mining , digging deeper , came later.

What is the Molarity of a solution made from dissolving 53.6grams of calcium carbonate in 0.94 liters of water?
It doesn't exist - calcium carbonate is limestone/marble - its insoluble
Why opencast mining is cheaper for companies?
because opencast mining doesnt require shafts and tunnels to be built unlike other approaches such as deep mining. it is on the surface so transportation costs from underground to ground level do not exist. insurance costs for miners may be lower as there is no risk of the mine 'caving in'.
