Mining
Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore. Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and …

1 of 2. next ›. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in ...
Just How Did The Ancient Greeks And Romans Cut …
Easing the cutting process with water was, indeed, one technique that ancient miners used to quarry stones. Another technique, though, was to use the natural …
Marble: the quarrying techniques – Carrara Marble Tour
The oldest technique was the "tagliata": the quarrymen, through the use of chisels, created cracks in the rock, especially where they found pre-existing cracks or chinks, obtaining a V cutting line. Then the crack was forced with metal elements (iron wedges), in order to obtain a deep one that caused the separation of the marble bench …
Marble: From Quarry to Sculpture » Geology Science
Extraction Methods: Open-Pit Mining: In open-pit mining, large pits or quarries are excavated on the surface to access marble deposits. Heavy machinery, such as bulldozers and excavators, is used to remove overburden (soil, rock, and vegetation) …
How is Granite Mined? Everything You Need to Know.
The layers of earth above which the stones are formed are firstly removed to uncover the granite. After this, an open cast mining process is used to extract it from the earth. The process includes drilling holes through the rock and then using hydraulic hammers to detach the individual blocks of stone from their surroundings.
Different Types of Mining | 4 Types of Mining
Some examples of mining assets include: Crusher – A machine designed to break down rock into smaller pieces. Conveyor belt – A long flat piece of metal that moves material along. Drill rig – A machine used to bore holes into the earth. Loader – A machine that picks up material and carries it to another location.
Quarrying methods: an international comparison

Gold Chlorination Processes & Methods
Chlorination Process for Gold. This process was based on the fact that chlorine, in the presence of moisture, converts gold into the trichloride AuCl3, which is soluble in water and removed by washing, the gold being then precipitated by ferrous sulphate, sulphur dioxide, hydrogen sulphide, or charcoal. Coarse gold requires long …
How Does Marble Get Mined From a Quarry? | Sciencing
Forming the Bench. Mining marble blocks from the wall of the quarry starts with a "bench wall." The bench wall is a large section of marble along a vertical wall that is cut with diamond cables, drills, and torches. Dynamite loosens the bench wall from the side of the quarry, and the separated wall can then be processed and cut into individual ...
Marble | Properties, Uses, Formation
Texture: Granoblastic, granular. Formation: Regional or contact metamorphic. Acid Reaction : Being composed of calcium carbonate, marble will react in contact with many acids, neutralizing the acid. It is one of the most effective acid neutralization materials. It is often crushed and used for acid neutralization in streams, …
How Is Granite Extracted? | Sciencing
Granite usually occurs in large deposits, many times referred to as slabs, throughout the world. Mining operations use different methods of cutting to extract the different deposits from the ground in places called quarries. These slabs are then polished, put on trucks and sent to fabricators. The fabricators will then cut the slabs into the ...

How Did Ancient Greece Get Marble?
Marble Mining Techniques. The Greeks used several techniques to extract marble from these quarries. One method involved using chisels and hammers to cut grooves into the rock along natural fracture lines. Wedges were then inserted into these grooves and struck with mallets to split the rock apart. Another method involved drilling …
