Bulk chemical composition of manganese deposits fom the Pacific and Indian oceans

Manganese nodules retrieved by early cruises of the R/V Hakuho Maru in the Pacific Ocean and the R/V Umikata Maru in the Indian Ocean have been chemically analysed. Samples were dried at 300°C in order to remove volatile water components and were then treated with 3N-hydrochloric acid and a few drops of 30% hydrogen peroxide. The acid soluble part was then submitted to atomic absorption spectrophotometry to determine the composition of Mn, Fe, Ni, Cu and Co.

Chemical composition in Pb and Zn of manganese deposits from the Pacific Ocean

Manganese nodules retrieved by early cruises of the R/V Hakuho Maru in the Pacific Ocean and the R/V Umikata Maru in the Indian Ocean have been chemically analysed for their content in Pb and Zn. Samples were dried at 300°C in order to remove volatile water components and were then treated with 3N-hydrochloric acid and a few drops of 30% hydrogen peroxide. The acid soluble part was then submitted to atomic absorption spectrophotometry to determine the composition of Pb and Zn. This information supplements that published on the same samples in Okada, A. & Shima, M. (1970).
