12.3 Primary Copper Smelting

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 furnace.

Copper Smelting Process Furnaces Used, By-Products, and

Sulphuric dioxide gas is created in smelting copper process and is converted sulphuric acid which is used in some of the smelting processes or sold as a by-product. Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace.

What Is Copper Smelting? (with pictures)

Dec 06, 2020· The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and purification to remove any remaining impurities. One of the main side effects of the copper smelting process is the production of waste. Refining copper results in three and a half times as much waste as the amount of copper produced.

Flash Smelting Process liming Outotec

The liming 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.

Copper Mining and Processing: Processing Copper Ores

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

copper-bearing scrap metal and smelting resi-dues requires preparation of the scrap (e.g., re-moval of insulation) prior to feeding into the primary process. Electric arc furnaces using scrap as feed are also common. Waste Characteristics The principal air pollutants emitted from the pro-cesses are sulfur dioxide and particulate matter.

Primary Copper Smelting Subcatergory And The Primary

Since, as discussed later, air pollution control specific to the reduction of sulfur oxide emissions to the atmosphere is prevalent at most primary smelters and since this control produces an important source of process waste water not found at the primary refineries, the primary copper industry should be divided into two subcategories: (1

The primary production of sulfide concentrates includes smelting to copper matte or blister copper, conversion of matte to blister copper, and refining to copper. Smelting, converting, and fire-refining can use a limited amount of secondary materials. Molten copper can effectively dissolve many metals, from valuable noble metals to harmful impurities such as bismuth.

Process Description Smelting Home

During the smelting process the liquid level in the furnace can rise and fall. Unlike a tuyere, the lance can be raised and lowered automatically or manually so that its tip is always where it is required. The products of the smelting ISASMELT™ process are tapped from the bottom of the furnace through a water-cooled taphole.

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. The copper ore coming from the mine (0.5 1 % Cu) must be concentrated by beneficiation.
