leaching processとは 意味・読み方・使い方

As the nickel smelting process using the high-temperature high-pressure acid leaching process in which nickel is leached out by a sulfuric-acid solution, a nickel smelting process in which leaching is performed by adding either or both of sulfur and a carbon compound to slurry to be subjected to leaching to control the oxidation/reduction potential (vs Ag/AgCl) of a leachate to 400 to 600 mV is used.例文帳に追加
