Kristiansand, Norway. Slag from the converter aisle is trans-ported by the Slag Hauler to disposal pits on site. The Acid Plant was commissioned in 1978 as part of the Smelter Environmental Improvement project. The Acid Plant treats the roaster off-gas, capturing the sulphur dioxide (SO 2) and producing a 93% sulphuric acid (H 2 SO 4), which is ...
the occurrence and speciation of copper in the slag the reduction of copper losses in the slag or the slag cleaning process could be suggested [3, 4]. In that context, this paper investigates the abundance and distribution of species of copper in various types of slags (flash smelting furnace slag, electric furnace slag
Paul Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum. With about 300 references, it is the most popular and effective means of processing blast furnace slag in the world today. The process is highly flexible; and the compact sub-plant can be applied to any furnace configuration.
The Toyo Smelter & Refinery is located in both Saijo City and Niihama City, Ehime Prefecture. The Toyo plant is a large-scale seaside copper smelter. It has established the world's top-class technologies for smelting, production control, and environmental preservation.
The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea. The first record of a reverberatory furnace is made by Jars, who states that copper-smelting was effected in reverberatory furnaces .
Nonferrous Smelting: Products . ... Elkem Silicon Slag Smelting Furnace in Norway ... Tenova Pyromet designed, installed and commissioned Southern Africa's first pig iron granulation plant at Saldanah Steel. The plant represents a significant breakthrough in the handling of molten pig iron.

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. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised ...
----- These additional sources of waste water evolution are not the subject of this document and will be (or have been) discussed in detail in subsequent (or past) rationale. Slag Granulation One source of process waste water found at several primary copper smelters is slag granulation.
The American Smelting Works.—At these works, in Leadville, Colo., a branch plant of the Aurora Smelting and Refining Company, the slag from seven lead-furnaces is granulated, as is likewise most of the matte made. The molten material is tapped from the furnace into a settling-pot.
• Fluid bed roasting, off-gas cleaning and acid plant • Electric furnace smelting • Converter aisle - matte converting, slag cleaning and matte granulation Figure 1 illustrates a schematic flowsheet of the plant subsequent to the feed preparation step. Figure 1: Sudbury Smelter – schematic arrangement of main plant .
Slag Granulation Plant – COPPEX – Tecnología. In cooperation with Kopar (Finland) we supplied and put into commercial operation a copper slag granulation plant for the largest copper smelter .

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

They are loaded into special rail cars or bundled onto flatbed trucks and shipped to the Asarco Copper Refinery in Amarillo, Texas. TOUR NOTE: Special clothing and safety equipment are required to visit a smelter, so we can't take you there on a tour. But the exhibits about smelting at the Mineral Discovery Center are the next best thing.
The smelting and refining of some metals can have special hazards. Examples include nickel carbonyl in nickel refining, fluorides in aluminium smelting, arsenic in copper and lead smelting and refining, and mercury and cyanide exposures during gold refining. These processes require their own special precautions. Other hazards
COPPER FLOTATION FROM SMELTER SLAG AND GRANULATED SMELTER SLAG**** Abstract Smelter slag is obtained in the process of metallurgical converting of copper concentrate in the Smel-ter Plant in Bor, Serbia. Today, the reserves of this material are evaluated at about more of a year, with the average copper content of 0.6-0.9%.
Sep 21, 2012· Smelters using slag milling and flotation for slag cleaning generally operate under conditions where most of the copper in slag would tend to form Cu 2 S upon cooling, although some metallic copper may still form via reaction 3. 7 Ideally, the slag should be slow cooled to allow most of the copper to form larger matte prills (over 30 μm in ...
of the matte granulation plants currently in operation at Waterval smelter. The pilot plant was subsequently de-commissioned in 2002. A Larox filter plant was commissioned in 2003, replacing the Eimco drum filters and Bateman filter presses that were in use, producing a superior filter cake for subsequent flash drying.
Paper - Slag Valorisation Symposium. Iron and steel slag (ferrous slags) are a potential heat/energy source. ... granulation plants using large volumes of water1, slowly cool it in slag pits eventually ..... the drums, but the drums are made of copper and the molten slag is transferred.
refineries. Slag is granulated and dried for recycling to the slag-cleaning furnace. ACP slag is fed to the slag-cleaning furnace along with a reductant and a sulphur source. Slag-cleaning-furnace matte is granulated for processing by the ACP, while slag is granulated and processed in the slag mill.
While reverberatory furnaces have very low copper losses to slag, they are not very energy-efficient and the low concentrations of sulfur dioxide in their offgases make its capture uneconomic. Consequently, smelter operators devoted a lot of money in the 1970s and 1980s to developing new, more efficient copper smelting processes.
