Copper extraction - Wikipedia
All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting.Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.. Carbonate concentrates are a relatively minor product ...
Primary and Secondary Smelting Operations
The Secondary Smelting Process Secondary smelting of lead is similar to primary smelting, but does not require the initial sintering process. Once lead is recovered from used materials, it is placed into a furnace where it is heated with coke or charcoal in order to isolate the lead from other compounds.
Primary Copper Smelter and Refinery as a Recycling Plant—A ...
a primary smelter and refinery is to produce copper, so the operation of any sub-system should not compromise this task. The main process stages for copper production include feed preparation, smelting, converting, fire-refining, anode casting, and electrorefining, also together six process stages or subsystems.
Copper Smelting Process - Furnaces Used, By …
Introduction to Copper Smelting Techniques. Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting.

Primary Smelting Process | High Quality Aluminum …
Primary Smelting is the process in which alumina is smelted into pure aluminum metal and the process through which new aluminum is made. As the origin of the aluminum supply stream, primary smelting has multiple phases of processing that require high-quality temperature and molten control.
Copper Scrap - an overview | ScienceDirect Topics
A considerable amount of copper scrap is used in primary copper smelters, and the amount and type depend on which process routes exist for primary concentrate. In primary smelters, heat is generated in smelting operations, especially in the Peirce-Smith converting of matte into blister copper, where the heat evolution is so great that coolants have to be used.
HIGH PRODUCTIVITY CLEAN SMELTING
process provides an innovative, high . intensity, yet low cost submerged lance smelting process that is easy to operate. It can be used for a range of applications including primary and secondary copper smelting and copper converting, primary and secondary lead smelting, primary nickel smelting and converting, and tin,
Lead smelting - Wikipedia
This process also keeps the lead from oxidizing. The molten lead flows from the blast furnace into holding pots. Lead may be mixed with alloys, including antimony, tin, arsenic, copper and nickel. It is then cast into ingots. Lead exposure. Humans have been smelting lead for thousands of years, poisoning themselves in the process.
OUTOTEC FLASH SMELTING TECHNOLOGY

More than half of the world’s primary copper and nickel is produced using Outotec’s proprietary process.
COPPER Copper production - Repository
Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities.
Copper Mining and Processing: Processing of …
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Flash Smelting Process - Outotec
The Outotec Flash Smelting Process is one of the world’s most commonly used processes for the production of primary copper and nickel. The process is based on our flash smelting principle, which utilizes the internal energy of the feed material for smelting, minimizing the need for external fuel and making the process very energy efficient.

Smelting Wikipedia. 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 stone reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
