Smelting - an overview | ScienceDirect Topics

Smelting furnaces produce liquid Cu–Fe–S matte (usually 60–70% Cu), which must have its sulfur and iron removed to make copper metal. This is most frequently done in submerged-tuyere Peirce–Smith (Fig. 4) and Hoboken converting furnaces using air (often slightly O 2-enriched) as the oxidant.The process is similar to submerged-tuyere smelting except that the feed is molten matte, not ...

From Ore to Finished Product - Copper

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.

Copper concentrate smelting is a large scale, intensive process consisting of four stages: sulphur in the sulphide minerals is "burnt-off"; the metals are melted to form a "matte" and the waste material forms a "slag"; copper in the matte is electro-refined to copper metal; and the gold/silver is refined to doré.

60 Centuries of Copper: Early Smelting Practice

Long afterwards smelting furnaces acquired the shape that they essentially maintained right down to Victorian Swansea days, i.e. a small stone or brick chamber with some means of pouring or ladling out the molten metal, a hearth below, and a brick chimney, usually low and stumpy, which provided an updraft and allowed the waste gases to escape.
