• BASALT POWDER

    Basalt is a magnesium-rich primitive rock containing also Silicon, Iron and Calcium and Trace minerals. It is a natural product, environmentally friendly with no elutriation/leaching into ground water. It is also non-toxic and safe to aquatic animals and plant-life.

    We are fortunate to have an excellent supply of raw basalt rock which we dry, crush and screen into various grades for a number of different industries at our factory in Cape Verde. Basalt is a hard, dense, dark volcanic rock composed chiefly of plagioclase, pyroxene, and olivine, and often having a glassy appearance. Basalt can be used in manufacturing and made into fine, superfine and ultra fine fibers.

  • MAIN BENEFITS OF BASALT POWDER

    Basalt powder will recondition the soil naturally, giving healthier plants, fruit and vegetables and higher yields, faster.

    Basalt powder is a soil enhancer and 100% remineraliser consisting of natural organic minerals.

  • THE MAIN CONSTITUENT ELEMENTS OF BASALT

    Silicates are necessary in building plant protein and in the synthesis of certain vitamins in plants. Silicates function as a vital element in protecting plants against insects and fungi attack, strengthening qualities and have been found to influence other minerals useful in plant metabolism...

  • THE BASALT FIBER

    Basalt is a mineral of volcanic origin, dark or black. It is a heavy, tenacious and resilient rock. Its density is approximately 5% higher than that of glass.

    Basalt fiber results from the treatment of basaltic rock, composed of minerals such as plagioclase, pyroxene and olivine. As a by-product of basalt's own casting process (single ingredient used in fiber production), basalt fiber is of superior quality to other known fibers for thermal stability, heat and sound insulation, vibration, durability and lightness, that is, in a summary form, it can be said that basalt fiber is a type of fiber with better performance with regard to the physical-mechanical properties.

  • CHARACTERISTICS

    In the industrial field, for example, basalt wool is produced by the melting of the basaltic rock at high temperatures, typically at 1450 ° C, and is subsequently transformed into fibres by a centrifuging process.

    These fibres have excellent chemical and thermal resistance, besides having low thermal conductivity associated to a perfect acoustic absorption. Basalt fibres with 9 to 11 microns are widely used in acoustical insulation of cars, stoves and other equipment where the cost-benefit ratio of thermal and acoustic insulation is relevant, such as in the automotive, aeronautics and aerospace industries, or in the home comfort.
