Copper Smelting - an overview | ScienceDirect …

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.

Copper processing - Roasting, smelting, and …

29-4-2020 · 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 …

How To Smelt A Gold Button By Roasting Sulfide …

22-8-2018 · In this video, we show the process of smelting down sulfide-rich gold concentrates to end up with a gold button. Through roasting, the sulfur is driven off, in turn, converting the metallic ...

Copper Smelting Chemistry Tutorial - AUS-e-TUTE

Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed. One of the reactions to remove iron impurities is shown below:

Smelting and Roasting Ores to recover gold, silver …

The product of melted sulfides is called a matte, and is highly corrosive liquid. Converting that molten sulfide matte to metal is called smelting. Small scale smelting can be done in a crucible – in fact that is what a fire assay is. When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix.

Gold Smelting & Refining Process

When the smelting process is complete, the charge is poured into a mold. Once the slag is cool, this can be separate from lead and precious metals by using a hammer or any device than can break the slag. The metallic product is named button and have to be processed in the other smelting process called cupellation.

Sulfide Smelting - Physical Chemistry of …

In recent years, roasting and smelting of sulfide concentrates are simultaneously carried out in a single furnace. The process known as flash smelting combines the benefits of flash roasting and matte smelting. The flash smelting of galena concentrate produces lead while those of chalcopyrite and pentlandite concentrates produce high‐grade matte.

Smelting - an overview | ScienceDirect Topics

Oxidation smelting is a process based upon an oxidation reaction, such as copper sulfide, matte smelting of nickel mineral raw material, matte blowing, or blast furnace smelting of antimony sulfide concentrate. The main reactions that occur during the smelting process are

Nickel processing - Extraction and refining | …

1-5-2020 · Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher …

Lead Smelting - Base Metal Smelting

A blast furnace is an enormous oven which is used to accomplish the smelting processes [2]. The process in which galena is smelted requires two important stone reactions to occur within the furnace. 1) The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide [2]. Roasting is a method where a ...

12.3 Primary Copper Smelting

In the smelting process, either hot calcine from the roaster or raw unroasted concentrate is melted with siliceous flux in a smelting furnace to produce copper matte. The required heat comes from partial oxidation of the sulfide charge and from burning external fuel. Most of the iron and 10/86 (Reformatted 1/95) Metallurgical Industry 12.3-1

CA1185095A - Process for autogenous oxygen …

ABSTRACT A process is disclosed for autogenous oxygen smelting of sulfide materials which contain base metals. In this process a sulfide material containing base metals is combusted autogenously with an oxygen-containing gas. The improvement resides in roast-ing a portion of the metal sulfide to be smelted, blending the portion of roasted material with further green metal sulfide…

ISASMELT™ Technology for Sulfide Smelting | …

19-8-2018 · Abstract. Since the development of the top-submerged lance (TSL) technology for copper and lead smelting by the cooperation of Mount Isa Mines (MIM), now owned by Glencore, and the Commonwealth Scientific Industrial Research Organisation (CSIRO) the core of the ISASMELT™ technology has always resided in the lance system.
