2021-3-12 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
2016-8-8 The development of copper smelting technology has experienced a long process,but now it’s still mainly use pyrometallurgy,its copper production accounts is about 85% of the world’s total copper.Henan Longjiang metallurgical chemical equipment Co.Ltd.(the following abbreviation Longjiang) reverberatory furnace and blast furnace are also dominated by pyrometallurgy.
Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Automating scheduling provides advisory information to operators.
A process of smelting a sulphidic copper ore concentrate comprising introducing and partially roasting the sulphidic copper ore concentrate in a whirling layer roasting furnace, separating hot roasting gases from the roasting furnace, mixing enrichment oxygen with the roasting gases, joining and mixing into a smelting flame combustible gaseous fuel and the oxygen enriched separated hot
2015-9-10 illustrates the Noranda process reactor. Flash furnace smelting combines the operations of roasting and smelting to produce a high-grade 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
High Quality Economic Small Copper Ore Smelting Furnace For smelting metal arc furnace is more flexible than other steel making process can effectively remove sulfur phosphorus and other impurities furnace temperature is easy to control the equipment covers small area suitable for smelting high quality alloy steel features usage smelting of high quality alloy temperture 20006000℃.
2 天前 Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace
