室温条件下将海绵金用王水溶解形成金氯酸溶液，再用纯净的不含金黄铁矿吸附溶液中的金，烘干后用过氧化氢溶液将其分解，发现溶液中出现粒状、片状及壳皮状金。对溶液中金和铁的含量测定结果表明，随着黄铁矿的分解溶液中铁含量增加，金含量也随之增加，但当溶液中出现小金粒或金片后，溶液中的金含量急剧下降，并保持相对稳定。
Under room temperature, the sponge gold is dissolved in aqua regia to form a solution of gold chloric acid, and then the gold in the solution is adsorbed by the pure gold-free pyrite. After drying, the solution is decomposed by a hydrogen peroxide solution and found to be granular in the solution, Shape and shell leather gold. The determination of the contents of gold and iron in the solution showed that as the content of iron in the decomposition solution of pyrite increased, the gold content also increased, but the gold content in the solution dropped sharply when gold or gold flakes appeared in the solution , And remain relatively stable.
