  • Process for preparing detergent builder Zeolite-A from Kimberlite tailings
    Patent number: 7560093
    Abstract: The present invention provides a process for the preparation of detergent builder Zeolite-A from Kimberlite tailing generated as solid waste during diamond mining is disclosed. The process comprises, reacting an acid treated Kimberlite tailing with alkali solution to obtain sodium silicate and reacting it with alkaline aluminum source at room temperature and crystallizing at higher temperature to obtain Zeolite-A. The product is useful as builder in detergent formulation.

  • Process for preparing amorphous silica from kimberlite tailing
    Patent number: 7037476
    Abstract: A new process is described for the preparation of free flowing hydrated amorphous silica from kimberlite tailing—a waste in diamond mining. The process 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.
