Electrum is an ancient gold alloy that was discovered thousands of years ago. Electrum is made mostly of gold and silver, but often contains smaller amounts of other metals, such as copper, iron, or palladium. Because the precise mixture of metals varies between deposits of electrum, the color also varies. Usually, electrum looks pale …
The name is mostly applied informally to compositions between about 20-80% gold and 20-80% silver atoms, but these are strictly called gold or silver depending on the dominant element..." Seems like electrum would generally be a green gold, but in the wiki they say:." It has also been produced artificially, and is often known as green gold.
You extract from raw materials to get individual components from them. Depending on the component it can be broken down further, used for catalyst or combine with others to make alloys and such. There is no actual game process for making the materials into bars. In short though, Cuprum, gold and silver all can be extracted from …

The gold used by the Egyptians generally contains silver, often in substantial amounts, and it appears that for most of Egypt's history gold was not refined to increase its purity. The color of a metal is affected by its composition: gradations in hue that range between the bright yellow of a central boss that once embellished a vessel dating ...

It takes (about) 4 times more nitric acid (67 - 70 %) to dissolve a gram of copper compared to dissolving a gram of silver. It takes (about) 1 ml nitric to dissolve a gram of silver - so (about) 4 ml of nitric to dissolve a gram of copper. So your cost for the acid goes up 4 times for every gram of copper you add to do your inquarting.

gold occurs as tiny inclusions or submicroscopic gold and are therefore refractory. Silver-rich ores and copper sulfide ores: Silver-rich ores and copper sulfide ores are often free-milling, but when the silver grade is high (>10 g/t) and/or the gold is present as electrum, the processing may need to be modified. The greater reactivity of silver
