  • Olivine, and the Origin of Kimberlite | Journal of .

    INTRODUCTION. Kimberlite, as illustrated in Figs 1 and 2, is a rock dominated by olivine.Most kimberlites are highly altered and their primary textures are poorly preserved, but rare examples, such as the sample from the Kangamiut region of Greenland shown in Fig. 1, contain about 50% of large fresh olivine grains, which are set in a matrix of finer-grained minerals.

  • process of olivine mining

    Mining, milling and spreading Enhanced weathering is literally a very down to earth method. It comes down to mining lots of Olivine rock, then milling it down to the level of sand, and subsequently spreading it in a humid place, where CO 2 will dissolve in water and react with the Olivine .

    1. Introduction. Olivine (O) sand is a natural raw material used by foundries to create moulds or cores particularly for casting manganese containing steels and is preferred to quartz sand as it minimizes the reactions between the liquid metal and the sand particles [].However, the ideal foundry sand particles should have a sub angular shape in order to allow the individual grains to interlock .
