| Abstract: | A new is described for the preparation of free flowing hydrated amorphous silica from kimberlite tailing--a waste in diamond mining. The comprises treating of kimberlite with acid, further reacting it with alkali solution to obtain soluble metal silicate solution, which is subsequently neutralized with mineral acid to polymerize silica as insoluble precipitates. The products is useful in rubber, paints as abrasive etc. |
