What is quarry in mining?
A quarry is a type of mine that is typically used for the extraction of rock or minerals from the earth. Quarries are typically used to extract building materials, such as dimension stone, construction aggregate, riprap, sand, and gravel. They can also be used to extract minerals that are used for vRead more
A quarry is a type of mine that is typically used for the extraction of rock or minerals from the earth. Quarries are typically used to extract building materials, such as dimension stone, construction aggregate, riprap, sand, and gravel. They can also be used to extract minerals that are used for various industrial and chemical purposes, such as limestone, gypsum, and talc. Quarries are often located near sources of raw materials, and they can be surface or underground operations. The materials extracted from quarries are used in a variety of construction, manufacturing, and other industrial applications

The difference between crystalline and amorphous
Crystalline solids are solids that are composed of a repeating, ordered arrangement of atoms or molecules. These solids have a regular, three-dimensional structure that is repeated throughout the solid, resulting in a highly ordered and predictable arrangement of the atoms or molecules. Crystalline solids are typically hard, strong, and have a high melting point. Examples of crystalline solids include metals, minerals, and some types of plastics.
Amorphous solids, on the other hand, do not have a repeating, ordered arrangement of atoms or molecules. These solids are characterized by a disordered, random arrangement of atoms or molecules, resulting in a less predictable structure. Amorphous solids are typically softer and more flexible than crystalline solids, and have a lower melting point. Examples of amorphous solids include glass, rubber, and some types of plastics.
One way to distinguish between crystalline and amorphous solids is through their physical properties. Crystalline solids typically have a higher melting point, are harder and stronger, and have a more ordered structure than amorphous solids. Additionally, crystalline solids often have a distinctive, repeating pattern when viewed under a microscope or through X-ray diffraction techniques. Amorphous solids, on the other hand, do not have a repeating pattern and tend to be softer and more flexible.
