Two-way Valorization of Blast Furnace Slag: Synthesis of …

Calcium is selectively extracted from the slag by leaching with acetic acid (2 M CH 3 COOH) as the extraction agent. The filtered leachate is subsequently physico-chemically purified and then carbonated to form precipitated calcium carbonate (PCC) of high purity (<2 wt% non-calcium impurities, according to ICP-MS analysis).

Mining in Japan - Wikipedia

Mining in Japan is minimal because Japan does not possess many on-shore mineral resources.[1] Many of the on-shore minerals have already been mined to the point that it has become less expensive to import minerals. There are small deposits of coal, oil, iron and minerals in the Japanese archipelago.[2] Japan is scarce in critical natural
