内容記述 The purpose of the work reported here is to describe the chemical characters of the manganese nodules produced within the lateritic soil of the Ryukyu Islands.The major and minor components of the manganese nodules, such as manganese,iron, silica, aluminum, calcium, magnesium, copper and nickel were analyzed, and also crystal structure were observed by mean of X-ray diffraction method.The following results were obtained. The characteristics of manganese nodules in the lateritic soil is that they contain ll.6%~24-9% of manganese dioxide 18.2% on the average, which is smaller than in other manganese ore. Copper and nickel content in the manganese nodules of lateritic soil is 0.009% on the average and it has a remarkable linear relation to the content of manganese dioxide, and also there exists inverse proportion between the amounts of copper or nickel and silica or iron. In order to see why manganese dioxide content were almost proportional\nto copper or nickel contents, copper solution (0.8mg/100m1) were treated with manganese dioxide. It was found that copper ion was remarkably absorbed by manganese dioxide, and it was inferred that copper and nickel were concentrated into manganese nodule by absorption from the subtropical lateritic soil. X-ray diffraction suggests that the manganese nodules of lateritic soil consist of amorphous manganese dioxide.
