While reverberatory furnaces have very low copper losses to slag, they are not very energyefficient 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.
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 subplant can be applied to any furnace configuration.

Smelting is a process of applying heat to ore in order to extract a base is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base 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 observed that the characteristic of the material was equivalent to the traditional ones or even better. So copper slag can be a potential alternative to the admixtures used in concrete and mortars. Investigation on the use of slag from copper smelting as fine aggregate in concrete was made by Akihiko and Takashi (1996). From mortar ...
The Toyo Smelter Refinery is located in both Saijo City and Niihama City, Ehime Prefecture. The Toyo plant is a largescale seaside copper smelter. It has established the world''s topclass technologies for smelting, production control, and environmental preservation.
Copper in the USA: Bright Future Glorious Past Copper Producers. At the beginning of copper''s flow through the economy are the mining companies, which process vast quantities of lowgrade ore, mostly from openpit mines in order to produce copper.
§ Installation of copper plate coolers on sidewalls Given the increase in the smelting intensity planned for the furnace at higher power, and to standardise the Mortimer furnace design with the Waterval furnaces, watercooled copper plate coolers are to be installed in the sidewalls in the slag zone.
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 Saldan Steel. The plant represents a significant breakthrough in the handling of molten pig iron.
The American Smelting Works.—At these works, in Leadville, Colo., a branch plant of the Aurora Smelting and Refining Company, the slag from seven leadfurnaces is granulated, as is likewise most of the matte made. The molten material is tapped from the furnace into a settlingpot.

of the matte granulation plants currently in operation at Waterval smelter. The pilot plant was subsequently decommissioned 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.

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 Smelter Plant in Bor, Serbia. Today, the reserves of this material are evaluated at about more of a year, with the average copper content of %.
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.
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 ...
refineries. Slag is granulated and dried for recycling to the slagcleaning furnace. ACP slag is fed to the slagcleaning furnace along with a reductant and a sulphur source. Slagcleaningfurnace matte is granulated for processing by the ACP, while slag is granulated and processed in the slag mill.
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 % 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.
