Pilot-scale Experimental Work on the Production of ...

2014-8-25  Producing precipitated calcium carbonate (PCC) from steelmaking slag (Slag2PCC) is a way to reduce CO2 emissions while at the same time turning slag waste into a valuable product. In the Slag2PCC process, a solution of ammonium chloride (NH4Cl) is used to extract calcium from steelmaking slag which is then bubbled with a CO2-containing gas in a process called carbonation to form PCC.

Pyrochemical recovery of plutonium from calcium

The plutonium-bearing slag is crushed and melted in the presence of at least an equimolar amount of calcium chloride and a few percent metallic calcium. The calcium chloride reduces the melting point and thereby decreases the viscosity of the molten mixture. The calcium reduces any oxidized plutonium in the mixture and also causes the dispersed plutonium metal to coalesce and settle out as a separate
