Refined Copper Smelting and Refining Process. 01 Formulation of copper concentrate. Large ships bring copper concentrates from overseas mines. The copper concentrates are unloaded by the berth's massive unloader, after which they are transferred to the storage yard where they are sorted and stored. After the concentrates are separated into ...
Feb 16, 2020· What is Pyrometallurgy? Pyrometallurgy is the branch of science and technology concerned with the use of high temperatures to extract and purify metals. Therefore, it is a branch of extractive metallurgy. This process can produce pure metals that are suitable for direct selling and alloys suitable as feed for further processing.
Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4
Aug 23, 2017· A History of Copper Processing. Pyrometallurgy involves the treatment of ores at high temperature to convert ore minerals to raw metals, or intermediate compounds for further refining ...
CHAPTER 04 Nonferrous Pyrometallurgy INTRODUCTION Development of continuous copper matte converting processes creates a strong demand for continuous copper fire refining. Copper refining requires two stages: oxidation with slagging of impurities and sulphur removal, and copper reduction before anode casting.
Pyrometallurgy is a process through which ores and metals are heated to produce a finished product of workable compounds, purer metals and alloys. The process may be any of the following: drying, roasting, smelting, refining, and alloying, among others. By using high temperatures, one can cause chemical and exothermic reactions in materials.
In pyrometallurgy, the copper is refined from polymetallic sulphides in four steps [1][2] [3]: smelting, converting, fire refining and electrolytic refining. In the smelting and converting steps ...
Refining is the removal of impurities from materials by a thermal process. This covers a wide range of processes, involving different kinds of furnace or other plant. The term, 'refining' can also refer to certain electolytic processes. Accordingly, some kinds of pyrometallurgical refining are referred to as 'fire refining'. Environmental aspects

Pyrometallurgy Basic Principle. The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation).
