Silicomanganese Slag
Felman Production generates a residual commercial by-product, silicomanganese slag, through the production of Ferro Silicomanganese (FeSiMn). The slag is an inert solid green material consisting primarily of aluminum, manganese, magnesium, silicon, and calcium oxides.
Production
The slag is generated during the production of ferro silicomanganese using electric arc furnaces. The molten slag is casted, cooled by spraying it with cold water, and then crushed to the desired size.
Potential Uses
Potential uses of the commercial by-product include re-melt/reproduction, industrial fill, road base, textiles manufacturing, etc.
Chemical Composition
Below please find the available metals totals for the chemicals that were detected as components of the slag material. The material is considered non-hazardous as shown by Toxicity characteristic leaching procedure testing conducted on the material. A qualified and licensed environmental laboratory is currently conducting a general assay of the material to determine the % w/w of the different chemical components.

Physical Aspects of the Material
The material is a hard solid stone that has irregular fracturing similar to chert or glass. The material is primarily green, gray, and black in color and is odorless. The bulk density of the material is approximately 635 +/- 100 kg/m3.
Material Size: Generally, one-to-four-inch stone, but can be crushed and sized to the clients desired specifications.
