copper smelting process pdf

The reverbs began to decline in the This two stage smelting and converting process is being considered for installation at a number of copper smelter sites. Figure 6 shows the charging procedure. This is accomplished through a series of several processing steps. Solid feed combined with the high level of oxygen enrichment produces a low volume of offgas, rich in SO2. Electrolytic copper refining –concentrate to wire in a single process • $1.9 million in funding from US DOE awarded to MIT to explore molten sulfide electrolysis as a potential replacement for the traditional pyro-metallurgical copper smelting process DE-FOA-0001465 The slag forming reaction is: FeO + SiO 2 → FeO.SiO 2 The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Pollution Prevention and Control Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature. Table 1 shows the example of the chemical compositions of them. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. More than half of the world’s primary copper and nickel is produced using Outotec’s proprietary process. Smelting technology is the world’s leading method for copper and nickel smelting. Leaching processes produce residues, while ef-fluent treatment results in sludges, which can be sent for metals recovery. It is a fossil fuel fired hearth furnace for smelting concentrate and producing copper matte. It can be used for a range of applications including primary and secondary copper smelting and copper converting, primary and secondary lead smelting, primary nickel smelting and converting, and tin, The process is highly energy efficient because it makes full use of the reaction heat of the concentrate, meaning The reverberatory furnace dominated copper matte smelting for much of the 1900s, because it was an excellent process for smelting fine concentrate from flotation. Automating scheduling provides advisory information to operators. The entire process con-tributes to considerable resource savings as opposed to the process of similar capacity with three converters. process provides an innovative, high . Copper matter is processed to copper blister in two 80 ton Peirce-Smith converters - one in opera-tion and the other under rebricking. 2. The distributions of copper and the other elements among the gas, slag and matte were also investigated. The smelting process typically produces less than 3 tons of solid waste per ton of copper produced. intensity, yet low cost submerged lance smelting process that is easy to operate. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall. The process is very easy to operate and is autogenous with combustion air enriched to approximately 30% oxygen. Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. copper smelting process. Experimental Methods Industrial copper concentrates, matte, slag and flue dust from Chilean smelters were used as test materials. In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron oxide, silica, and … 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. Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. contain 0.5–0.7% copper and is frequently used as construction material or for sandblasting.
