Very few smelters in the world can treat complex concentrates especially in the quantities that the Tsumeb smelter can. Owning this smelter secures the fate of Dundee Precious Metals concentrate, and can ultimately generate a separate revenue stream due to the addition of
The smelter takes a by-product of the smelting process and turns it into something of value for Namibia. The Tsumeb smelter produces 98.5% pure copper blisters and with its ability to treat complex copper concentrates is transitioning from a captive smelter, receiving mainly Dundee concentrates into a toll treatment facility with brownfields expansion potential.

Hydrometallurgical considerations in processing
In any successful hydrometallurgical process treating copper-arsenic concentrates, key results would include high copper extraction during leaching and arsenic deportment to a stable residue. As most of these concentrates also contain significant levels of gold and silver, recovery of these precious metals cannot be overlooked.
Copper Cliff Smelter Near Sudbury, Canada The Diggings™
the smelter operation is complex, since most copper/nickel operations produce a combined white metal which is separated at the refinery; this smelter produces both copper and various nickel products with internal process cross flows, thus it is difficult to establish a clear cut break between copper and nickel in terms of cost or energy analyses.
Ust-Kamenogorsk Metallurgical Complex consists of a 190'000 tpa Zinc Refinery, a 144,000 tpa Lead Smelter, a 70'000 tpa Copper Plant the Precious Metals Refinery and theAcid Plant. The production site is located near Kazzinc's administration within the city's boundaries, with all
For several years a study group at the Technical University of Berlin has investigated the volatilization of impurities, such as lead, antimony, zinc, and bismuth from complex copper concentrates in a dispersed reaction and smelting system (similar to laboratory-scale flash smelting).
trating, and fire refining. Ore concentrate is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. Smelting of roasted ore concentrate produ-ces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS) and some heavy metals. By con-verting of matte, the high-grade "blister" copper of
1. Wide adaptability to raw material, from iron, copper, copper-nickel, zinc, lead and zinc-lead complex concentrate; 2. Application of rich-oxygen air blast offers high smelting temperature, enhances hearth capacity and generates high concentration SO 2 gas suitable for sulfuric acid-making; 3.

The smelter employs approximately 800 people. The smelter is one of only a few in the world that can treat complex copper concentrates. Blister copper and sulphuric acid are smelter products. The blister copper is delivered to refineries in Europe and Asia for final processing to copper metal.
Copper Cliff Smelter Complex Date March 6, 2017. Smelter Feed CuNi Ratio Permanent Transition. The first major milestone in our move to a single furnace Clean AER flow sheet operation is the lowering of the copper content in Smelter feed.
Copper Concentrate an overview ScienceDirect Topics
Arsenic, antimony, and bismuth can be leached from copper concentrates before smelting to improve the quality of the concentrate and to recover these elements. An alkaline solution of sodium sulfide is used, and the thiosalts formed are treated further for recovery or disposal.
The purpose of this study was to investigate the reduction smelting of antimony concentrate obtained in the course of lead production. The blend was prepared by mixing antimony concentrate with coke acting as a reducing agent. The reduction smelting was carried out in alundum crucibles in a shaft furnace with silicon carbide heating elements.

Kosaka Smelter is believed to be one of the most outstanding smelter, which contribute to the complex sulfide concentrates in the world, with our up-to-date metallurgical technology, this paper described about the experience of practical operation at Kosaka Smelter in the last decade.
The smelter sources materials from customers domestically and from international customers in Africa, Australia, Far East, Middle East, North and South America. Equipped with both Pyro and Hydro metallurgical capabilities, the smelting complex is capable of treating the following materials, Borax slags, Flue dusts, PC scrap, Milled concentrates
The smelter, which employs about 700 people, is one of only a few in the world able to treat complex copper concentrates that contain arsenic and is, therefore, able to conclude long-term favourable contracts to treat such concentrates, notes DPM. Tsumeb
Glencore starts copper concentrates blending facility in
Complex concentrates, partially treated ore that contains 0.5% or more arsenic, cannot be processed by most smelters in the world for safety reasons and need to be blended first before they can be processed into refined metal.
Concentrate imports have duly risen steadily, surpassing 600,000 dmt in 2016, with an estimated lead content of around 350,000t. While the smelting complex includes an Ausmelt plant with a throughput capacity of 100,000t/y of secondary materials, the latest expansion is based on primary feed and concentrates now account for around 75% of total feed.

Nyrstar to invest in Hobart project to treat more complex concentrates Nyrstar is to invest A$52 million ($38.6 million) on four growth projects at its Hobart smelter in Tasmania, including two projects to boost the plant's capacity to treat more complex concentrates.
the zone in the vicinity of the copper smelter plant in Bor (Serbia). On the other hand, practically it is difficult to obtain the proposed level of arsenic in the air, after smelting copper concentrates produced by a selective flotation procedure applied to the sulfide ore deposits .

Applying Ausmelt processing to complex copper smelter
Ausmelt technology opens up new opportunities for the economic processing of complex copper smelter dusts. Not only can the technology separate more of the unwanted elements to produce a clean blister copper for refining, but it can also allow production of fume and precious metal products that can be readily upgraded to produce high-grade, valuable products.

Because of long processing times en countered with conventional treatment of PGM sulfide concentrates and the ultimate probable dependence on a foreign smelter and refinery to produce the platinum group metals, alternative processing of Stillwater Complex concentrates is
The smelter is a custom copper smelter which uses both copper concentrates and precious metal-bearing recyclable materials as its feedstock to produce a 99.1% copper anode. The anode is shipped to the Canadian Copper Refinery (CCR) in Montreal to be converted into 99.99% copper cathodes which are sold on world markets.
