slag from smelting of copper nickel ores

sulfide copper-nickel ores [1, 2]. Extraction of platinum from sulfide copper-nickel ores is a multi-stage process. One of the stages of this process is melting of a previously prepared concentrate in electric ore smelting furnaces [3], where the melt is divided into sulfide and oxide components (matte and slag).

slag from smelting of copper nickel ores. How copper is made material used processing steps Many copper ores also contain significant quantities of gold silver nickel and other valuable metals as well as large quantities of commercially useless material Most of the copper ores mined in the United States contain only about 12 16% copper by weight The most common sulfide ore is chalcopyrite ...

The invention relates to a method for smelting nickel-copper from sulfide ores by virtue of a pyrogenic process and extracting iron. The method comprises the following steps: by taking a mixture of quicklime, quartz sands and nickel ores or a mixture of quicklime and nickel cores as raw materials, smelting copper and nickel in a smelting furnace; by taking slag as a raw material, extracting ...

05-09-2013· selective reduction followed by magnetic separation, Nickel can be produced from laterite ores by reduction−smelting, the slag Nickel and copper constitute 0 . Slag - Wikipedia. Ore smelting In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals

Keywords: Copper smelting, Slags, Microstructure, Thermodynamic modelling. ABSTRACT Effective extraction of copper from sulphide ores requires careful operation of a copper smelter, which in turn depends very much on the chemistry of the feed and the resulting slag and matte.

Nickel Slag - an overview ScienceDirect Topics. Lead, lead-zinc, and zinc slag are formed during pyrometallurgical treatment of the sulfide ores. This process is similar to the production of copper and nickel slag, including roasting, smelting, and conversion. Phosphorous slag is a by-product of the elemental phosphorus refining process.

Abstract. Plenty of valuable metals, such as cobalt, nickel, copper, manganese and lithium, are present in spent lithium-ion batteries. A novel smelting reduction process based on MnO-SiO 2-Al 2 O 3 slag system for spent lithium ion batteries is developed, using pyrolusite ore as the major flux. And Co-Ni-Cu-Fe alloy and manganese-rich slag contained lithium are obtained.

Nickel Slag an overview ScienceDirect Topics. Lead, leadzinc, and zinc slag are formed during pyrometallurgical treatment of the sulfide ores This process is similar to the production of copper and nickel slag, including roasting, smelting, and conversion Phosphorous slag is a byproduct of the elemental phosphorus refining process

Ore smelting. In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that ...

The Smelting of Copper-Nickel Concentrates in an Electric. Copper-nickel-sulphide ores mined in the Rustenburg district of South Africa are generally smelted in electric furnaces because of the high-temperature slag produced, the availability of chea~ electric power, and the smaller pollution problems.

Recovery of copper from smelting slag by sulphation roasting and water leaching 411 Materials and experimental methods Experiments were conducted using a reverberatory furnace slag from the Bor Copper Concentrator, Serbia. The slag was sampled from the crushing line before entering the milling section of the concentrator.

from nickel sulfide ores often contain other metals such as copper, and precious metals, and consideration should be given to further processing for their recovery. Slag can be used as construction material after nickel recovery as appropriate (e.g. return of converter slag to the furnace). Sanitary sewage effluents require

Roasting of copper converter slag containing 4.03% copper, 1.98% nickel and 0.48% cobalt with ammonium sulphate open to atmosphere has been carried out in order to achieve sulphation of copper ...

Lead, lead-zinc, and zinc slag are formed during pyrometallurgical treatment of the sulfide ores. This process is similar to the production of copper and nickel slag, including roasting, smelting, and conversion. Phosphorous slag is a by-product of the elemental phosphorus refining process.

The copper slag usually contains Fe 2 O 3, SiO 2, Al 2 O 3 and CaO. On the average, one ton of the copper slag is produced from each three tons of the extracted copper. Yearly production of copper reaches 20 mln . Get Price [] Lecture 20 Smelting Contents NPTEL. matte of copper‐nickel is an intermediate product. Next is copper‐ nickel matte.

14-11-2013· Recovery of Zn, Cu, and Fe from the copper smelter slag was studied. Slag was treated with NH 4 Cl at 320 °C and product was subjected to water leaching. Metal recoveries to the solution were 91.5% Zn, 89.7% Cu, and 88.3% Fe. Metals were subsequently precipitated using ammonia water.

13-01-2021· Slag formed in the smelting and converting reactions flows to the slag well. Slag cleaning occurs as a result of contact with lower grade matte in passing through zone 1, by the roast reaction of copper sulfide and copper oxides by the reduction of copper oxide by sulfur and ferrous sulfide, and by the reduction of magnetite.

The content of nickel in the lixivium of scrap copper smelting slag reaches 640mg/l while the zinc content is more than 100g/l. This high content of nickel in the solution must not only be separated from the leachate for resource recovery, but also for the subsequent zinc electrowinning which need to keep the nickel content less than 1mg/l to make the...

03-05-2014· Copper and nickel slags are produced by (1) roasting, in which sulfur in the ore is eliminated as sulfur dioxide (SO 2); (2) smelting, in which the roasted product is melted in a siliceous flux and the metal is reduced; and (3) converting, where the melt is de-sulfurized with lime flux, iron ore, or a basic slag and then oxygen lanced to remove other impurities.
