I remember reading many years ago (60s?), that Chinese rural regions were being encouraged to produce their own iron from locally available materials. This was because iron ore, limestone and charcoal/coal were often locally available and the cast iron produced was sufficient for many purposes without further refinement.

IIRC the furnace was simple and based on 40 gallon drum(s). I don't remember how it was blown.

Does anyone know the details of the Chinese furnace?

These are all just variations of what is called a Bloomery. If you do a web search for "bloomery" you will find a bunch of info.

Some people took advantage of a hillside bank to build their bloomery/chimney into - and get the air supply by natural hot-air currents and any local wind. Others used variations of a bellows to supply the air. Some even used falling water from a waterfall to create "compressed air" to supply it to the bloomery.

A book that might be of interest to you would be

Darrell Markewitz of Wareham Forge has compiled a CD-ROM of his and his friends attempts at re-creating a Viking era iron smelt. "Iron Smelting in the Viking Age" with over 600 images including working plans. A web search will bring you to his web site.

Tons of info on low-tech iron production.

Ah yes. I remember near Grassington in Yorkshire there were long tunnels built up the hillside as chimneys for lead smelting.
