提出应用酚类化合物苯酚还原酸浸大洋多金属结核的新方法。试验研究表明，苯酚是多金属结核酸浸的高效有机还原剂，常温（室温）常压下，添加少量苯酚，将多金属结核矿样在稀硫酸介质中浸出２０ｍｉｎ，各有价金属即可得到很高的浸出率（％）：Ｃｏ＞９８、Ｍｎ＞９７、Ｃｕ＞９５、Ｎｉ＞９５，与常规无机还原剂相比具有明显优越性。该方法还可应用于陆地难浸氧化矿的处理，具有很好的实际应用前景
A new method of phenol-reduced acid leaching of polymetallic nodules using phenolics was proposed. Experimental studies show that phenol is an efficient organic reductant for acid leaching of polymetallic nodules. Under normal temperature (room temperature) atmospheric pressure, a small amount of phenol is added to leach the polymetallic nodule sample in a dilute sulfuric acid medium for 20 minutes, and the respective valuable metals are obtained High leaching rate (%): Co> 98, Mn> 97, Cu> 95, Ni> 95, compared with the conventional inorganic reductant has obvious advantages. The method can also be applied to the treatment of land-hard oxide ore and has good practical application prospect
