Feb 14, 2018The revisions to the Process System now make it possible to produce gold, iron and zinc oxide from the Slag Pile without grinding the raw slag with a High-Pressure Grinder Roller ("HPGR") or the use of an autoclave. This is achieved by fine-grinding the glass produced from the slag and leaching it in ambient conditions.

Method to Determine the Carbon Cost of Slag Production. To determine the part of CO 2 due to the slag production in the BF process route (carbon cost of slag), a differential reasoning can be developed. The difference in overall emissions of an increase of slag quantity while keeping the hot metal production exactly at the same level should give a reliable estimate of the CO 2 impact of the

12.5 Iron And Steel Production 12.5.1 Process Description1-3 The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles.
