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
Optimization of the flotation of copper smelter slags from Namibia Custom Smelters'' Slag Mill Plant Elias Sipunga A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, in partial fulfillment of the requirements for the degree of Master of Science in Engineering
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.
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.
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.
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.
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.
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 .
Kristiansand, Norway. Slag from the converter aisle is transported 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 offgas, capturing the sulphur dioxide (SO 2) and producing a 93% sulphuric acid (H 2 SO 4), which is ...
is returned to the rake classifiers. The smelter is a zeroeffluent plant and all the water from the slag silos where the slag is dewatered, as well as the storm water, is pumped to the process water dam from where it is pumped back into the plant for process water use. The offgas from the furnace is drawn through a forced draught cooler and ...
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 ...
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 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 coppersmelting was effected in reverberatory furnaces .
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.
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
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.
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 %.

§ 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.

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 ...
