How iron is madematerial manufacture making history

The Ore Extraction and Refining Process Before iron ore can be used in a blast furnace it must be extracted from the ground and partially refined to remove most of the impurities. Leaning on his long tongs this young iron puddler s helper posed for this photograph in the early 1860s when the Sons of Vulcan was a young union.

Lime in Flotation and Recovery Processes Graymont

Lime is used extensively in the recovery of gold and silver. Ores either run-of-mine milled autoclaved or roasted are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.
