04/12/2020 · copper smelter plant direct to blister process (PDF) Fluxing options in the directtoblister Direct smelting of sulphidic copper concentrates to blister copper involves clear benefits in the smelting operation, in particular if modern flash smelting technologies are used.
In this paper methods under development in COCOP for optimisation of a copper smelter including plantwide control and unit process advisory tools, are introduced and discussed. The main focus of the paper is in describing the development work relating to the .
A commercial plant has been in operation since 1978 at Glogow in Poland, to smelt a low ironsulfur, carbonaceous, comparatively highcopper concentrate directly to blister. Direct smelting to blister is only practical where the levels ofPb, As, Bi, etc., in the concentrate are low.
A process for autogenously smelting copper sulfide ore concentrate directly to semiblister copper in which a calcareous flux is charged directly to an autogenouse furnace along with concentrate and coppercontaining coolant. Furnace products are semiblister copper, calcareous slag .

23/08/2017 · Copper Loss in Slag: The slag from the smelting process is cooled, crushed and ground before flotation to recover copper sulphides and copper metal. Typically, slags may contain 3% copper .
The Mufulira smelter, one of two operating copper smelters on the Zambian Copperbelt, currently processes over 400,000 tonnes of copper concentrates per annum, most of which is sourced from MCM's mines Mufulira and Nkana mines. Concentrate and other copper bearing feed materials (eg. copper oxides) are also obtained
intermittent SO2 flow to the sulfuric acid plant in a copper smelter [6, 7]. In this process the matte from a flash smelting furnace is cooled, crushed, and ground, then fed to another flash smelting furnace to produce blister copper (Figure 2). In other words:
12/11/2013 · Along with actual evolution in the processing equipment, the basic metallurgy has been under careful evaluation and development. In spite of many favourable features of iron silie slags, they become problematic in the directtoblister copper smelting environments, at oxygen partial pressures higher than in matte smelting.
The sulphur dioxide gases generated in the smelting process is collected and ducted to the Sulphuric Acid Plant. Set up with basic engineering from Kvaerner Chemetics, Canada, the plant is based on the absorption process known as DCDA, and has a designed .

Direct Blister Process Outotec. The Outotec Direct Blister Process offers new options for using different raw materials and optimizing plant layout while minimizing investment, operating costs, and the environmental impact even further Results in high recovery of copper and other valuable metals ; Ensures low investment and operating costs for smelter
The matte produced by the flash smelting furnace is transferred to the Converter furnace. Oxygenenriched air is blown into the Converter furnace to oxidize the matte further to create blister copper with a grade of approximately 99%. Reaction in the converter. Cu 2 S・FeS + SiO 2 + O 2 → Cu + 2FeO・SiO 2 + SO 2 + Reaction heat.
