What Are The Characteristics Of Natural Red Copper?

Generally speaking, the purity of natural red copper is quite high, mostly only contains trace tin, lead, antimony, nickel and other metal impurities.

The pure copper smelted by the original technology often contains not only more metal elements associated with copper ore, such as lead, tin, zinc, iron, etc. And because the smelting temperature is not high enough, the copper and slag are not well separated, so that it will be mixed with silicon, calcium, magnesium, aluminum and other oxides.
