Most of the nickel ores imported to Japan are so-called “Garnierite Ores” from New Caledonia. For the effective extraction of nickel, l experimented on some properties of this ore and obtained the following results:
1) The principal constituents are Serpentine, Talc, Quartz.
2) Possible nickel-bearing minerals are Serpentine, Talc, Garnierite.
3) When the sample is heated
(i) At 130 & deg;C, adhered water is removed.
(ii) At 330 & °C, goethite loses its combined water.
(iii) At 654 & °C, serpentine loses its water and becomes amorphous.
(iv) At 816 & °C, decomposed serpentine changes to forsterite. Talc transforms into forsterite, also.
