Mining

Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

What is the value of beryl?

User Avatar
The value of beryl is highly variable. At the bottom would be ore-grade beryl, worth whatever the going rate of beryllium is. At the top would be gem-quality emerald, one of the most precious of all gems, worth thousands of dollars per carat.

What does quartz mining mean?

User Avatar
Primary gold typically occurs in quartz veins. The extraction of gold ore from these hard quartz veins was historically referred to as quartz reef mining. A Prussian engineer, Jacob Brache was the first to think that quartz reefs might have even more gold than alluvial fields. The new mining companies had to sink very deep shafts to get quartz from the reefs deep underground. Horizontal tunnels called drives were dug out from the shaft at different levels to find the gold-bearing rock. All rock dug out had to be hoisted to the surface. So did lots of water and even the workers at the end of the day. Big engines were installed to hoist lifts and buckets up the shafts. On the surface above the shaft stands a building known as the poppet head or pit head. The poppet head contained a wheel called a gin wheel which lifted buckets of rock up to a raised platform called a Brace. Wheeled buckets then carried the rock along elevated tracks to waste dumps or processing works. The steel cable that hoisted the bucket passed over the gin wheel. The gold was brought to the surface as small particles embedded in lumps of quartz. The quartz was then crushed into a fine dust by stamping batteries in a stamping mill. A stamping battery contained a row of stampers. On the bottom of each stamper was a heavy piece of steel. Each stamper was connected to the cam shaft which was turned by a water wheel. The steel shoes went up and down between wooden guides and pounded the quartz which had been fed into steel boxes underneath the stampers. Ideally the stamping batteries would work 24 hours a day. After crushing, the quartz dust was mixed with water to make sloppy mud which then ran down sloping tables, called concentrating tables. On top of these tables were copper sheets coated with mercury, which attracts gold. The gold particles stuck to the mercury, and could be collected from there. I ! :D

Why was mining one of the most dangerous jobs in the west?

User Avatar
Working deep underground, in unstable rock, and handling explosives, with nothing in the way of safety gear or modern technology like rock bolts and emergency breathing systems, was very dangerous indeed.

How does mining nickel ore cause pollution?

User Avatar
The machines companies use to mine the ore create polutive gases. There is likely a better answer and this one should not be taken seriously but it is an idea that spawns from your question and it can be researched and proven.

What is acid mine drainage caused by?

User Avatar
Sulfide ore still in the mine reacting with ground water and air from the tunnel/shaft/pit producing sulfuric acid. [e.g. 2 ZnS + 2 H2O + 3 O2 --> 2 Zn + 2 H2SO4] This acid mixes into the ground water and either drains from or accumulates in the mine. When it accumulates in the mine it can enter the aquifer, contaminating wells and springs supplied by the aquifer.

Bronze is an alloy of copper and tin. Answer 2: Bronze is a general term describing alloys of copper, the most common type of Bronze today is an alloy of copper and tin (often lead or other materials are added too to improve quality). In the early Bronze Age Bronze made with Copper and Arsenic was the most common type.

What is quartz used for?

User Avatar
Quartz is used in the making of sandpaper, optics, glass, liquid filters, circuit boards, computer components, cement , mortar, and jewelry. Quartz crystals are also piezoelectric meaning when an electrical current passes through them they vibrate a small amount. Time can be measured from the vibrations of the quartz crystals so quartz crystals are often used in clocks.

What happens to ore after it's been mined?

User Avatar
Extracted Ore is crushed smelted, a chemical process usually requiring huge quantities of heat at very high temperature, to extract the metal from the mineral that was the ore. Eventually each specific ore deposit is exhausted and the mine falls into disuse.

There are a few aspects of manufacturing that require transportation costs to be paid. One such aspect is receiving materials to manufacture a product with. Another reason transportation costs would be involved is when the products are being sold.

How do you get aluminum from the ground?

User Avatar
Aluminum metal is too reactive chemically to occur as pure aluminum in nature. Instead, it is found combined in over 270 different minerals. The main ore from which aluminum is extracted is bauxite. Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. Approximately 95% of the world's bauxite production is processed first into alumina, and then into aluminium by electrolysis. Bauxite is converted to alumina by first heating it in a pressure vessel along with a sodium hydroxide solution at a temperature of 150 to 200 °C. At these temperatures, the aluminum in the bauxite is dissolved as an aluminate (the Bayer process). After separation from the residual mud (from which most of the aluminum has already been extracted) by filtering, pure gibbsite is precipitated when the liquid is cooled, and then seeded with fine-grained aluminium hydroxide. The gibbsite is usually converted into alumina (aluminum oxide, Al2O3), by heating. The alumina is then mixed with cryolite (Na3AlF6, sodium hexafluoroaluminate) and heated to about 1000 °C. The cryolite helps the alumina form a liquid solution. The aluminum is then separated by passing a lot of electricity through it (electrolysis). This separation is called the Hall--Héroult process after the men who developed it. Before the Hall--Héroult process was invented, producing aluminum was much more time consuming and expensive - to the point that aluminum dishes and utensils were considered more exotic and a mark of greater wealth than gold or silver dishes and utensils. Napoleon III, Emperor of France, is reputed to have given a banquet where the most honoured guests were given aluminum utensils, while the others made do with gold.
