The Smelting of Copper University of Worcester

The Smelting of Copper The first written account of the processes of smelting and refining of copper is to be found in the 12th century.1 On smelting: Copper is engendered in the earth. When a vein of which is found, it is acquired with the greatest labour by digging and breaking. It is a stone of a green colour and most hard, and naturally mixed with lead. This stone, dug up in abundance, is

Smelting Furnace an overview ScienceDirect Topics

7.5 Copper Smelting. Copper can be produced either pyrometallurgically or hydrometallurgically. The hydrometallurgical route is used only for a very limited amount of the world's copper production and normally is considered only in connection with in-situ leaching of copper ores. From an environmental point of view, this is a questionable production route. Several processes can be used for

Cancer incidence among copper smelting and nickel

Background: Among workers employed at a nickel refinery in Harjavalta, Finland an increased risk of lung and sinus cancer has been demonstrated in two previous studies. The current study adds 16 more years of follow-up to these studies. Methods: A total of 1,115 persons exposed to nickel and 194 non-exposed workers in the Harjavalta nickel smelter and refinery were followed up for cancer from

History of Ancient Copper Smelting Pollution During

Determination of copper concentrations in Greenland ice dated from seven millennia ago to the present showed values exceeding natural levels, beginning about 2500 years ago. This early large-scale pollution of the atmosphere of the Northern Hemisphere is attributed to emissions from the crude, highly polluting smelting technologies used for copper production during Roman and medieval times
