- Q: Im doing a project on mercury a 5 page essay to be exact and i need loads of information on mercury. Specifically How is it obtained and processed from the earth, Where is it found, What is it like in its pure state, I also need to list qualitative and quantitative descriptions, state uses of the metal, are there toxic qualities associated with this metal, what is the cost per pound or ounce of it.
- The last mercury mine in the US, McDermitt Mine in Nevada closed in 1991. It was an open cut mine using trucks and an excavator to mine a vein of quartz that contained the mercury mineral cinnabar. - mercury sulfide. Cinnabar is a red mineral, usually earthy in appearance but can form red crystals. The USGS reports that red cinnabar can still be seen in rocks in the waste pile at the mine. Cinnabar is the most common mineral for primary mercury production. Underground mines in China also mine cinnabar. The process used at McDermitt was to roast the ore in a stream of air. The cinnabar reacted with oxygen to produce sulfur dioxide and mercury vapor. The mercury vapor was condensed from the air stream. Mercury is produced as a by product of electrowinning of copper. The mercury collects together with other metals as a sludge at the bottom of the electrowinning tanks. One of the biggest produces of by-product mercury is the Yanacocha Gold Mine in Peru. Mercury occurs along with the gold. Yannacocha is a large surface mine using electric shovels and trucks. The process at Yanacocha is to treat the ore with cyanide solution, which dissolves both the gold and the mercury. Both gold and mercury are precipitated on carbon , from where there are again redissolved with cyanide and then precipitated with zinc powder. The loaded zinc is the smelted to recover the gold and mercury. The mercury is vaporised in the smelter and recovered by the pollution control equipment. The price of mercury has been hovering around $600 for a 76 lb flask. Use of mercury is declining and is down to about 2000 tons per year. Much of this is provided by recycling. The use of florescent lights for energy saving may increase consumption. Mercury is very hazardous. The links give more information.
- Q: It's about 10 x 15 feet and also includes a wooden deck.
- Call an excavator for an estimate. To clear it out and haul away expect at least $1000, maybe more depending on factors involved.
- Q: It must include either gears, pulleys,belt drives, cams, or levers. In the report include; when it was invented, who invented it, why it was invented, how it works and what it is called?Minimum of 2 pages, max 4.Include Bibliography.
- Search for the tunnel excavator by horizontal boring , that was used to construct the tunnel between England and France
- Q: Where were the Dead Sea Scrolls took after they had been found?
- The story of how those scrolls traveled from the hands of young Bedouin goatherders to be under the scrutinous eyes of international scholars is stranger than fiction. Although all the details of the next few years will probably never be known for sure, this much is clear. After hanging from a pole in a Bedouin tent for a period of time, the seven original scrolls were sold to two separate Arab antiquities dealers in Bethlehem.

- Q: Introduction of excavator
- First, the definition of excavators, excavators, also known as mining machinery (excavating machinery), is digging with bucket mining materials above or below the surface of the machine, and loaded into the transport vehicle or dump to the stacker of earthmoving machinery. The main materials are soil, coal, sediment and soil and rocks that have been pre - loosened. From the development of engineering machinery in recent years, the development of excavator is relatively fast, and excavator as one of the most important construction machinery models in engineering construction, the correct selection is also more important. Two, a brief history of excavator first hand excavator has been developed for more than 130 years of history, has experienced a gradual development process of automatic hydraulic excavator driven by steam rotary bucket excavator to the internal combustion engine and electric drive rotary excavator, application of mechatronics technology during the. The first hydraulic excavator was successfully invented in japan. Due to the application of hydraulic technology, 1940s has been installed in the tractor equipped with a backhoe hydraulic excavator suspension, in early 1950s, and have been developed in the mid towed rotary hydraulic excavators and crawler hydraulic excavator.
- Q: the question is' the city of rubber ville plans to dig a rectanguler landfil. the landfil will have a base with demensions 700 ft by 200 ft and a depth of 85 ft.'1- how many cubi feet of garbage will the landfill hold?2- what information would you need to determine how long the landfil can be used until its full?3- an excavator was hired to dig the hole for the landfill. how many cubic yards of dirft will he have to haul away?i reaally dont get this!can you please explain 1, 2, and 3 to me??
- Well for number 1, simply find the volume by multiplying the given dimensions For number 2, you would need to know approxamitely the volume of trash going in daily, or something along those lines For the third, convert dimensions to yards, then multiply them? That's how I would do it, unless I misread the question
- Q: obviously, i can't really get a yes or no answer on this,but what i'm actually looking for is, what proof is there that the trojan war could have possibly happened?so far i've got- Parry's experiment in regards to how the story was passed down- Ancient Historians (herodotus, [he spoke about wife stealing])- Archaeological evidence (they found a possible site of Troy)- I NEED MORE!!!!!! any other ideas, even if they are just your own stupid theories)
- Troy also is mentioned in Thucydides, The Peloponnesean War, book i. Of course, the fundamental problem is that the story does not get written down until about 400 years after it happened. Best estimates for the war are 1250 BCE; Homer lives in the 800s BCE, so there is a major time period in between. This is shown by some of the errors in Homer's account, for example, the claim that the Greeks and Trojans burned their dead on funeral pyres. In fact, much of what we know of Troy and other Achaean sites comes from grave shafts -- buried people. So, the Homeric accounts are distorted by time and include some invention. At the same time, Troy VI does have many of the characteristics of Troy as described, and Troy VIIb does show signs of destruction by fire. From Thucydides, we know Greek armies were not very competent at storming walled positions, so the possibility of a lengthy war of siege is quite real. Troy is mentioned in other Greek legends, and it could be that there is a fusion of accounts -- the earlier, greater Troy (Troy VI) gets transplanted into the story of the war (Troy VIIb). This kind of compression is common in such ancient accounts, including Genesis in the Bible, where long periods of time separate event and history. Other Achaean sites discovered include Mycenae, Sparta, and Pylos, all mentioned in the poem. There is a great deal of Cretan and Mycenaean art recovered, including some displayed in the New York Times about 35 years ago. You should be able to find books on this subject. Archaeological evidence from the other Achaean sites include large numbers of account tablets, suggesting that any war which did occur was more likely about trade rather than the hand of a woman.
- Q: Why do we have to experience a faltering of our faith? How can we avoid a dark night of the soul?
- That's simple enough. How close are you to the light. If you take your focus off of Jesus and the plans He has for you the darker it gets. Stay close to the light and darkness won't be insurmountable. Isn't it amzing what a prayer can do. When it all seems hopeless it will pull you through.
