Q:How is COPPER obtained form COPPER--RICH ores?
Electrorefining Apparatus for electrolytic refining of copper The copper is refined by electrolysis. The anodes cast from processed blister copper are placed into an aqueous solution of 3–4% copper sulfate and 10–16% sulfuric acid. Cathodes are thin rolled sheets of highly pure copper. A potential of only 0.2–0.4 volts is required for the process to commence. At the anode, copper and less noble metals dissolve. More noble metals such as silver and gold as well as selenium and tellurium settle to the bottom of the cell as anode slime, which forms a saleable byproduct. Copper(II) ions migrate through the electrolyte to the cathode. At the cathode, copper metal plates out but less noble constituents such as arsenic and zinc remain in solution. The reactions are: At the anode: Cu(s) → Cu2+(aq) + 2e– At the cathode: Cu2+(aq) + 2e– → Cu(s)
Q:What is the price of scrap copper?
The price of scrap copper along with all other scrap metals has decreased significantly. You did not indictate if the scrap copper was cable, wire, buss bar, stripped cable, etc. therefore it is hard to tell if that is a fair price. If it was cable (not stripped) then that was a fair price. If it was clean copper then that seems low. For current, daily and historical pricing for scrap metals please check the source below
Q:question about copper and oxidisation?
Not vague at all. Copper oxide will dissolve in hydrochloric acid according to the equation CuO(solid) + 2 HCl(aqueous) --> H2O(liquid) + CuCl2(aqueous) This is a typical reaction between a basic oxide, and an acid, to make a salt and water. You will seethe copper turn pink and shiny, the colour of fresh copper metal, and the solution will turn blue or greenish blue because of the dissolved copper salt. Copper is not reactive enough to dissolve in HCl. if you tried this experiment with the more reactive metal, such as zinc, the metal itself would also dissolve and give hydrogen: Zn(solid) + 2 HCl --> ZnCl2(aqueous) + H2(gas)
Q:what is the importance of copper in the society?
pennies are not made from copper anymore. That would mean the base metal used is about 200x the value of the penny itself. Copper today is used largely in electrical for wiring because copper is an excellent conductor. It is also quite commonly used as plumbing piping because it is non-ferrous so you wouldn't get an irony taste in your water, it is quick to use and does not corrode as easily as ferrous metals when used in a plumbing application. Plastic products today tend to be replacing copper more and more but it will always be used on a commercial/industrial level. It also gets used for high pressure gas supplies of natural gas, nitrogen, medgas, etc. Also, additional fact, scrap copper is about $4 per lbs at the moment where I live.
Q:Is copper a good metal to make coins with?
It is a very good metal for coinage. However, it is increasingly expensive. U.S. pennies have had very little copper in them since 1982; they are mostly zinc. If they were still mostly copper, the copper content alone is worth more than one cent, never mind the cost of manufacture and distribution. Copper half dollars are much more economical. Probably the best metal for coinage that combines lowest cost and sufficient durability is aluminum. Many countries around the world have produced aluminum coins for years.
Q:Is Copper Safe harmful to guppy fry?
DONT USE COPPER SAFE!!! what ever you do dont use it. why? one the company just verified that it is not safe. and i agree with the company. copper safe is VERY powerful and even using just a smidge of it can harm ur tank. honestly dont understand why its still in the market. it is really harsh stuff and half the time there is always another remedy or treatment that will do the same thing as copper safe and yet still be safe for your tank. what temp did you crank your tank to? it should be around 82-84 if you want to killl the ich off quickly. and how much salt did you put in? need to make sure you only added one teaspoon of salt per five gallons of water.and if you are going to do any treatment, your safest bet then would be using RID-ICH form KORDON. and just use half a dose. its safe for most situations. and just as a notecopper safe is not exactly safe. go figure. . . anyways if u used copper safe, it can linger in your tank for up to a year! and it would be near impossible to keep live plants and scaless fish in your tank after the treament.

Q:Why use copper pans?
Copper is an excellent conductor of heat, especially good for top-of-range cooking. Cooks often prefer copper cookware for delicate sauces and foods that must be cooked at precisely controlled temperatures. Copper cookware is usually lined with tin or stainless steel. The Food and Drug Administration (FDA) cautions against using unlined copper for general cooking because the metal is relatively easily dissolved by some foods with which it comes in contact, and in sufficient quantities can cause nausea, vomiting and diarrohrea. So take care when you use them.
Q:what are some of the uses for of copper.does it combine with other elements. what are they.?
Copper; is an essential mineral (metal) for life. Is the primary component in our electrical wiring, our motor's coils, our generator's coils and it is often used to transfer remigration fluids. Copper is also one component in Bronze and Brass and the ability to smelt the softer metal allowed the Bronze Age of technology. Brass is important because of its natural germicide properties (despite all the nasty fluids in a brass spittoon it doesn’t harbor bacteria cultures). Copper metal does react with hydrogen sulfide and sulfide containing solutions.
Q:Does copper power get rid of marine itch?
Copper medications will help get rid of ich, but they must be used in a hospital tank with no live sand or live rock. The copper in the medicine will bond with the calcium carbonate in the rock and sand, so don't use it in your display tank. A simple bare-bottomed 15 gallon tank will suffice, and use a filter with mature media.
