Dirt is the most economical choice, but almost any block can be used. The hole you bury them in does not need to be lined with any specific block, and can even be open underground as long as there is material above the Tailings. Burial is the key to mitigating Tailings pollution. The deeper you bury the tailings, the less leakage occurs.

In other words, Rich Slag is worth one bar of any metal you choose. The process of smelting rich slag with dust also has a chance of producing normal slag. Note that the Rich Slag produced by the induction smelter can be used to increase the yields of any metal as long as you have at least two metal dusts to smelt them with.


"Slag cement" is also used at times to refer to a very specific material, as it is in ASTM Standards C2191 and C5952. In C219, slag cement is defined as a "blend of granulated blast-furnace slag and hydrated lime in which the slag constituent is more than a specified minimum percentage." C595 gives the minimum percentage applicable in that
