Copper extraction

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated)

Copper dissolves while cementing. Gold Refining & Metal Extraction

Mar 12, 2022 If you immerse copper pipe to the solution, mercury will precipitate from the solution together with other values. If you aren´t sure, never smelt the cemented metals. Rather dissolve them again in AR and proceed from there. By doing this, you circumvent possible mercury volatilization during heating and smelting.
