Copper processing - Roasting, smelting, and converting ...

Roasting, smelting. , and converting. Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or fluidized-bed type.

How to Make Gold from Mercury: 7 Steps (with Pictures) - wikiHow

Mercury is relatively easy to turn into gold, so it will be used as the starting material. This method is not a terribly practical or economically viable way to go about making gold, but if you're interested in how it works, you can learn the science behind the process.

Refining Gold | HowStuffWorks

When gold is combined in this way, it forms an alloy. Scientists and goldsmiths often use colors to designate the various gold alloys that are possible. For example, white gold is made by combining gold with nickel, silver or palladium. Red or pink gold is an alloy of gold and copper. And blue gold is the result of mixing gold with iron.

Copper Mining and Production Processes Explained

Open-pit 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore. An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding. The ore is crushed, then ground into powder. Concentrating. The ore is enriched using a process called froth flotation.

"Instead of trying to knock protons out of lead, protons can be borrowed from metals with lower atomic numbers and added to make gold." Pidasso said the lab, a division of the U.S. Department of Energy, first achieved the transformation by borrowing protons from copper and nickel and adding them to bars of iron.

Can you turn other metals to gold..Alchemy? | Yahoo Answers

Historically, Alchemy, was an attempt by alchemists to turn base metals into gold. With the modern understanding of nuclear chemistry, and radioactive decay, the trans-uranic elements (Actinides) can transmutate into other elements, for example Uranium spontaneously changes to Thorium and this in turn changes to Protoactinium and so on until ...

The Extraction of Copper - Chemistry LibreTexts

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas.
