This two stage smelting and converting process is being considered for installation at a number of copper smelter sites. The process is very easy to operate and is autogenous with combustion air enriched to approximately 30% oxygen. Solid feed combined with the high level of oxygen enrichment produces a low volume of offgas, rich in SO2.

Copper Mining and Processing: Everything you Need to Know

In most copper smelters the primary smelting process produces a low to medium grade matte. The converter carries out the bulk of the oxidation where between 30 to 80% of the sulphur originally in the concentrate is eliminated. Traditionally, converting is a two-cycle batch process …

12.3 Primary Copper Smelting

Copper Smelting Process: Historically, the most abundant copper bearing ore was called chalcopyrite, CuFeS 2. This ore is first enriched by a process called flotation. Powdered ore is mixed water as a slurry and then further mixed with oil and a chemical called amyl xanthate.

Egyptian Copper Smelting Process | MATSE 81: Materials In ...

Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed. One of the reactions to remove iron impurities is shown below:

Copper Smelting and Refining Process | Pan Pacific Copper

The Egyptian copper smelting process utilized a 'bowl furnace' which was supplied additional air, to raise the temperature of the fire, through the usage of foot bellows. Malachite and azurite were used as a source ore for the copper, charcoal was used as the reducing agent to separate oxygen from the copper…

Hong Yong Sohn, ... Bart Blanpain, in Treatise on Process Metallurgy: Industrial Processes, 2014. 2.1.1.6.1 FeO–Fe 2 O 3 –SiO 2 Slags. It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO 2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces now use basic ...

How copper is made - material, used, processing, steps ...

Copper processing - Copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...

Processes. Copper is found in natural ore deposits around the world. This page explains the production route taken from extraction of ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.

Smelting - Simple English Wikipedia, the free encyclopedia

Smelting is the general term for getting a metal from its natural ore.Gold is an exception because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore.. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.Most ores are oxides, sulfides or carbonates.

A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting …
