Smelting Iron Ore

[Andre ROUSSEAUParticipant @andrerousseau66124]

Trying to find a web-link(s) that can tell me more about the German development of low shaft-height blast furnaces during WW2 that enabled them to use Thermal coal for coking (their dirty Lignite). The resulting iron had a high Sulphur content. I believe that a lot of this work was centred in Colbe (not sure about the accuracy of that name). Anyone have any information?

Also, additions of Manganese are used to de-Sulphurise molten iron. How much access to Manganese did Germany have in WW2?

Hi Andre,

During the campaign against the Sovjet Union the Germans had access to Manganese in southern Ukraine. They also got Manganese from Hungary and Romania.

I think Mushet was early in realising manganese was beneficial against the negative effects of sulphur and thus made it practical to get high quality iron from resources mainly in Forest of Dean (I think they had sulphur in coal as well?). I think he got his manganese from iron ore in Rhenish mountains… Germany. Practical quantities might not still have been available by WW2.
