Between glass copper stainless steel and cast iron which one holds heat longer?
Cast iron holds heat longer compared to glass, copper, stainless steel.
How do you extract copper by smelting?
Copper ore is first crushed and ground into a fine powder. It is then heated in a furnace along with a reducing agent such as carbon or coke, which removes oxygen from the ore and leaves behind the copper. The molten copper is then cast into molds to form solid copper bars or ingots.
How is coppper exstracted from its ore?
Copper is extracted from its ore through a process called smelting, where the ore is heated to high temperatures in a furnace with carbon, which reduces the copper oxide to copper metal. The molten copper can then be cast into shapes or further processed to purify it.
What is copper phytomining?
The world is running out of rich copper ores. Research is being carried out to find new ways to extract copper from the remaining low-grade ores, without harming the environment too much. This research is very important, as traditional mining involves huge open-cast mines that produce a lot of waste rock.Some plants absorb copper through their roots. As a result of this they concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds. This process is known as photomining.
Is the best insulators wood thermoplastic copper cast iron?
The best insulator among the materials listed is wood. Wood has a low thermal conductivity, making it an effective insulator. Thermoplastics also have good insulating properties, while copper and cast iron are conductive materials which do not make effective insulators.
Can copper dwv attach to a cast iron drain system without a dielectric union?
yes. A no-hub coupling or FERNCO (brand name) coupling work well.
Can you connect a copper fitting into a cast iron pipe without a dielectric union?
Certainly, if the pipes are kept dry, and don't carry an electrolyte, such as water.Otherwise, it's a bad idea to directly connect different metallic pipes. In fact, most plumbing codes prohibit such a connection.That's because anytime any two dissimilar metals contact each other -- while in the presence of an electrolyte -- whichever metal has the higher electropotential will corrode, through electrolytic action.So, in the case of copper vs iron, the copper side of the joint will eventually fail due to corrosion -- unless you electrically isolate the two metals.You can do this via a dielectric union, or dielectric nipple. Or, you can use a hardened brass fitting, which resists corrosion and also smooths the dielectric potential between the copper and steel.Of course, another author may have a different opinion (like the one below.) So my advice is to understand the 'why' of electrolytic corrosion, so you can determine whether or not, in your case, a dielectric union is advisable.####Of course , NO Problem and there are many ,many options of doing so.The electrolytic conditions happens when connecting ferrous metals to non ferrous metals that contain zinc (galvanized) if you think about it EVERY SINGLE CAST IRON RADIATOR has a brass shut off valve, Most black steel gas line have a BRASS gas valve. Brass bolts are the best way to go when installing CAST IRON ROOF DRAINSAlso why use a dielectric union when there are dielectric nipples less chance of leakage
Can you screw a copperfitting into a cast iron pipe without a dielectric union?
Of course NOT A Problem as electrolytic action most of the times happen between piping that contains galvanized coating (Zinc) Cast Iron radiators for example have BRASS valves which can contain as much as 85% copper If one looked at the clean outs of cast iron piping the CO's are brass with never any adverse actions
Can you use cast iron clamps on copper pipe?
Not directly without some type of sleeving or protection between them. They are dissimilar metals and it will create electrolysis which will severely impair the copper pipe and create holes in the copper in the future.
What is the effect of Copper in Cast Iron?

You want to replace old lead pipe connected to cast iron sewer pipe with copper How do you connect the copper pipe to the old lead pipe or to the cast iron pipe?
When I have to connect copper to lead "D" I usually solder the copper to the lead or wipe a lead joint depending on the diameter To connect copper to cast iron ,.... If there is a hub I caulk the copper directly into the CI with oakum and poured lead (molten) OR one can solder / braze a female adapter fitting and screw the copper into a CI female fitting
What actors and actresses appeared in The Coy Copper - 1920?
The cast of The Coy Copper - 1920 includes: Hank Mann
Why does die cast copper parts fetch a higher scrap price than bare wire?
castings made from copper alloy are a higher grade of copper than the copper in wire. Also, the insulation on the copper wire needs to be removed,
How is mineral such as gold or copper is mined?
Solid Minerals such as Gold and Copper are mostly mined using the Open Cast Method.

Between glass copper stainless steel and cast iron which one holds heat longer?
Cast iron holds heat longer compared to glass, copper, stainless steel.
Can you connect rigid copper to cast iron pipe?
If the copper is big enough, you can treat it as if it were cast and use packing and sealant. If the diameters are too different, you can use a rubber coupling to connect the two.
