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)

Feb 12, 2022 Feb 2, 2022 #1 Hello gents! Ive been keeping my copper waste solutions from my silver refining in 5 gallon buckets filled with iron for about a month at a time to ensure the copper and other metals are being cemented out before further processing. They have agitation (bubbler) going constantly.

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.
