Copper is sold in three main forms: refined copper cathode; copper concentrate; and blister copper. A very small amount of high grade copper is mined and direct shipped to a smelter (direct shipping ore, or DSO). Refined Copper Cathode. Cathode comprises all of the refined copper sold, excluding copper .

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
Oct 26, 2012· A new continuous process for conversion of copper mattes to blister copper has been successfully pilottested and is now ready for commercial application. The process, known as KennecottOutokumpu Flash Converting, involves reaction of solidified matte particles with industrial grade oxygen, in a flash furnace, to produce blister copper and a small quantity of slag which can be recycled to the ...
Feb 13, 2004· China imports mainly No 2 copper scrap and the lowerquality No 6 and No 7 grades, including wire, cable, small motors and power generators that contain less than 80 percent copper metal. Lion said smelters had little choice but to pay higher prices for prompt delivery of copper scrap. "They cannot turn their back on the market for the quite ...

General Information The Głogów Copper Smelter comprises two process lines – Głogów I smelter and Głogów II smelter. Both use the technology of singlestage flash smelting of copper concentrates directly to blister copper with an approximately % Cu content. The final product is cathode copper with a Cu content of %, registered on the London Metal .
Nov 28, 2019· Copper rose steadily through November on the back of positive developments in the USChina trade war and continued civil unrest in Chile. Declining stock levels have also supported prices. However, an underlying slowdown in enduse demand endures, despite .
The history of making blister copper in an Outokumpu Flash Smelting Furnace dates back to the late 1960''s, when Outokumpu first piloted the Outokumpu Direct Blister (ODB) process.

Sep 24, 2019· All of these process copper scrap and concentrates, typically to produce blister copper of 9899% copper content, which is an intermediate product used in cathode production. The five smelters have combined primary smelting capacity for 375,000 tonnes per year of blister copper, according to data seen by Fastmarkets.
Flash furnace smelting combines the operations of roasting and smelting to produce a highgrade copper matte from concentrates and flux. In flash smelting, dried ore concentrates and finely ground fluxes are injected together with oxygen and preheated air (or a mixture of both), into a furnace maintained at approximately 1000°C (1830°F).
The Outotec Flash Smelting Process is one of the world''s most commonly used processes for the production of primary copper and nickel. The process is based on our flash smelting principle, which utilizes the internal energy of the feed material for smelting, minimizing the need for external fuel and making the process very energy efficient.
May 17, 2018· Trial operations from next month should mark the start of a new wave of copper smelting and refining capacity in China, which should boost copper concentrate imports but could also cap growth in import demand for cathode and blister copper. At million tonnes, China''s copper concentrate imports in the first quarter 2018 were up % and ...
Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of % purity. Copper can be recycled indefinitely without the base metal being compromised ...
Blister copper was first produced in the pilot furnace of the Metallurgical Research Centre at Pori in 1969 and the first commercial plant for direct blister production was commenced in 1978 in Poland. This paper is a survey on the effect of oxygen potential or matte grade on the metallurgy of smelting copper concentrates in a flash smelting ...
