Recycling is important if we want to preserve this planet for our future generations. It is good for the environment since we are making new products from the old products which are of no use to us. Recycling begins at home; if you are not throwing away any of your old products and instead utilising it for something new then you are actually recycling.

Aug 31 2021 Crushed stone is used for concrete aggregate for road building and in the case of limestone as flux in blast furnaces and for chemical applications. The quarrying technique consists of drilling and blasting to fragment the rock. A large number of charges are fired at one time producing up to 20000 tons of broken stone in one blast.
Aggregate is also used to make concrete and asphalt. For this reason asphalt and concrete plants are often built next to quarries. Asphalt is an oily substance that is mixed with aggregate for road construction. Concrete invented by the ancient Romans is a mixture of sticky stone cement and aggregate.
Although the basic process is the same each quarry is different and some of the things in Quarry Story may not apply to all operations. Geography geology and the type of stone mined how close a quarry is to neighbors the size of the operation and the main transportation method used to get the stone products to customers all have an impact .

Mining is the process of extracting buried material below the earth surface. Quarrying refers to extracting materials directly from the surface. In mining and quarrying water is used and gets polluted in a range of activities including mineral processing dust suppression and slurry transport. In addition water is subtracted from the environment in the process of dewatering the process of pumping away the water that naturally flows into the pit or tunnels of the mine.
