copper extraction and purification

Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below). The anodes for this process were traditionally lead-based alloys, but newer methods use titanium or stainless steel.

Extracting copper. Extracting copper.

Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper. This is similar to the electrolysis that is done in a school lab.

Copper extraction

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing ...

Processes

First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

12.3 Primary Copper Smelting

typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduceimpurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as adried and heated charge for the smelting furnace. Smelting of roasted (calcine feed) or unroasted(green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide(FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to99.5 percent copper. Typically, blister copper …

What Is Copper Smelting? (with pictures)

Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
