提出抗坏血酸还原酸浸大洋多金属结核的新方法。常温（室温）常压下，加入少量抗坏血酸，在稀硫酸溶液中浸出２０ｍｉｎ，多金属结核中有价金属即可达到较高的浸出率（％）：Ｍｎ、Ｎｉ、Ｃｏ＞９８，Ｃｕ＞９７。抗坏血酸还原酸浸法还可成功应用于软锰矿、锰银矿等陆地难浸氧化矿的处理。
A new method of ascorbate-reducing acid leaching of marine polymetallic nodules was proposed. A small amount of ascorbic acid was added at room temperature (room temperature) under normal pressure. After leaching in dilute sulfuric acid solution for 20 min, the higher leaching rate (%) of the valuable metals in the polymetallic nodules could be achieved: Mn, Ni, Co> 98, Cu> 97 . Ascorbic acid reduction acid leaching method can also be successfully applied to pyrolusite, manganese silver and other land-hardened oxide ore processing.
