Using Furnaces to Improve Mining Processes
A version of the bloomery furnace that survived into the 19 th century was the Catalan Forge in Spain.. Blast Furnaces. Blast furnaces have largely superseded bloomery furnaces. These single-chamber furnaces produce pig iron, which has a higher iron content than the bloom created by the bloomery furnace.

Mine Hill
The first step in processing the siderite was to roast the ore in one of two large ovens. This drove off some of the carbon and sulfur, which may have caused problems in the furnace. B uilt of Roxbury granite and topped by a tall chimney, the cold blast furnace was at the heart of Mine Hill's iron-making venture.
