The Copper Flash CC Smelting Process :: Total Materia

Flash smelting is a pyrometallurgical process for smelting metal sulphide concentrates. It is used primarily for copper sulphide concentrates, but it is also used to a significant extent for nickel sulphide concentrates. The flash smelting process for sulphide concentrates was developed by the Finnish mining company, Outokumpu Oy, from 1948

Flash Smelting an overview ScienceDirect Topics

2011-2-3  The novel flash ironmaking process, conceived by Sohn [52] at the University of Utah, is based on the gaseous reduction of iron oxide concentrates in a flash reactor. It takes advantage of the large specific area of fine particles of iron ore concentrate, much like the flash smelting of copper or nickel sulfide concentrate. Although there are

Copper Smelting Process Furnaces Used, By

2020-12-23  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 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised

2008-12-16  Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 1 %

How copper is made material, used, processing,

The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.

From Ore to Finished Product Copper

2021-1-3  Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Nickel element extraction, mining technique flash

The extraction process of nickel is a procedure of steps followed as in the case of copper. Certain processes executed rely on the fact if the ore is a sulfide or a laterite, accompanied with usage of high temperature refractories and smelting furnaces.

2010-12-1  1. Introduction. Copper smelter flue dusts are generated in the pyrometallurgical process of copper extraction. The constituent elements, and their concentrations, depend on: the characteristics of the sulfurated ores that are processed, the species and their concentration, the reactor-type used in the different stages of the process and the conditions under which these stages operate.

2020-12-14  At Olympic Dam the concentrate is flash-smelted directly to blister copper. In this process copper concentrate is fed into the smelter with oxygen-enriched air. The fine concentrate reacts or 'flashes' instantaneously as the sulfur fraction of the copper sulfides is

Copper: smelting, producing and classification

Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

Taskinen, Pekka; Jokilaakso, Ari; Lindberg, Daniel; Xia

Copper industry uses several technologies compared to most other metals [1]. As a result of its predominantly sulphidic raw materials, severe harmful emissions to atmosphere and soil have been local and global problems. In the 70 year history of the Flash Smelting process

Prediction for Matte Grade in the Process of Copper

Firstly, the nonlinear relation model between matte grade and craft indicators in copper flash smelting process was established by using the LS-SVM. Secondly, the parameters of LS-SVM were optimized by using the QPSO algorithm.
