SMS DEMAG has introduced a new generation of threeelectrode type rectangular furnaces in the mar ket. 4. DESIGN PRINCIPLES OF LARGE SCALE FENISMELTERS The smelter unit in the FeNi plant comprises – the calcine transport system, – the slag and metal tapping facilities ...
Process for recovering nickel and nickelcopper from molten smeltertype slags or other highly oxidized sources of nickel and nickelcopper containing 7 to 30 percent by weight of magnetite (Fe 3 O 4 ). The magnetite in the slag is reduced with carbonaceous materials or other solid reductants such as sulfides, metals or carbides. While the slag is mixed with a fluid cooled, metalbladed ...
smelter were adapted to porphyry copper ores. With the exception of leachingsolvent extractionelectrowinning, the basic methods of cop per production have remained unchanged for 65 years. Moreover, six of the mines opened between 1900 and 1920 are still among the major copper producers in the United States today. Instead of great leaps forward, technological innovation in the copper ...
Copper panels will cool the furnace sidewalls to protect them from slag conditions, a separate gascleaning plant being installed so that no additional load is placed on existing environmental ...
The new reactor technology can also be used for existing platinum production lines to replace conventional electric slag cleaning furnaces and primary smelters. The intensive slag reactor is...
In 2009, Tenova Pyromet completed the refurbishment of two coppernickel slag cleaning furnaces for Norilsk Nickel. In 2010, Tenova Pyromet commissioned a new 12 MVA smelting furnace for Lonmin ...
01/01/2020· Slags are basically formed by fluxing agents used to aid high temperature liquidliquid separation in furnaces. The gangue portion of the ore, with the help of fluxes, is absorbed in the slag phase during smelting while the valuable portion is tapped off as matte. Slags have found a wide range of applications in civil engineering, fertilizer production, road construction, cement production and ...
Copper Slag cleaning in (electrical) furnaces has been increasingly popular over the last decades. METIX, part of the SMS group, has recently constructed an electric furnace for the First quantum project at Kanshansi, Zambia. The plant was commissioned successfully in February 2015. Figure 4: 3D illustration of Kansanshi Copper Smelter
45% nickel) and a fluid slag. Furnace matte still contains iron and sulfur that are oxidized in the converting step to sulfur dioxide and iron oxide by injecting air or oxygen into the molten bath. Oxides form a slag which is skimmed off. Slags are processed in an electric furnace prior to discard to recover nickel. Process gases are cooled followed by removal of particulates by gas cleaning ...
the huelva smelter facilities include a rotary kiln dryer, outokumpu flash furnace, electric slag cleaning furnace, 3 piercesmith converters, 2 anode furnaces, a double mold casting wheel, a single contact acid plant and a double contact acid plant. production capacity is 160, 000 mtpa anode copper.
Slag cleaning at copper and nickel smelters is typically done using an electric furnace process. The design of Outotec slag cleaning furnaces is based on our extensive experience with different slag compositions and under standing of how to optimize the process for maximum recovery.
With the Outotec Electric Slag Cleaning Furnace, the cleaning of smelting furnace slag is carried out using surface coke reduction in an electric furnace. The circular or rectangular electric furnace is operated in batches and equipped with three or more Söderberg electrodes.

XSM stone crushing machine projectore smelter plant electiic slag cleaning furnaces price
reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and ...
Submergedarc furnaces as well as electric smelters are typical plants for ferroalloys, silicon metal, and nonferrous metals. Primarily, electric slag cleaning furnaces are used in the nickel, copper, and platinum group metals industries to recover precious metals from slag. This began in the 1950s when SMS group installed its first units.
Ore that has been ground to a ˜ne powder arrives at Vale''s Smelter from Clarabelle Mill and is sent to the Filter Plant for moisture removal. From there, the powder is roasted and then melted in the Smelter furnaces at 1300 degrees Celsius. This allows the metals to separate from a waste material called slag.
Especially slag cleaning furnaces have supplied more than 20 in the last 40 years. Slag cleaning furnaces are commonly connected to smelting units such as Teniente and Noranda converter, Outokumpu flash smelter, reverbertory furnaces. The main function of the furnace is the reduction of the matte and metal level in the slag.
Turnkey specialists in the design and supply of electric submerged arc furnaces and complete smelting plants for the production of ferroalloys, basemetals reduction, slagcleaning and alloy ...
Copper ore typically contains only about % 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. The ore is crushed, screened, and washed before being further processed ready to supply the smelting furnace.
Introduction Coppernickelsulphide ores mined in the Rustenburg district of South Africa are generally smelted in electric furnaces because of the hightemperature slag produced, the availability of chea~ electric power, and the smaller pollution problems.
are then removed by gascleaning devices. Nickel Refining Various processes are used to refine nickel matte. Fluid bed roasting and chlorinehydrogen reduction produce highgrade nickel oxides (more than 95% nickel). Vapor processes such as the carbonyl process can be used to produce highpurity nickel pellets. In this process, copper and precious metals remain as a pyrophoric residue that ...
what are the nickel smelting equipments. Traditional smelting equipments have blast furnace, reverberatory furnace, in low tariff areas or smelting the difficult furnaces materials can also be used electric furnace bblowing blown the air into the molten low nickel matte, make the ferrous sulfide be oxidized into ferrous oxide and react with quartz sio slagging, produce the nickel
Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.
Slag should be landfilled or granulated and sold. Modern plants using good industrial practices should set as targets total dust releases of – kg/t of copper and SO. 2 . discharges of 25 kg/t of copper. A doublecontact, doubleabsorption plant should emit no more than kg of sulfur dioxide per ton of sulfuric acid produced (based
