<p>The invention relates to technology for the production of sorbents, in particular to methods for producing a binder consisting of natural glauconite for manufacturing granulated sorbents, and can be used for the removal of technogenic pollutants from drinking water and industrial effluents, and for purifying gases to prevent harmful emissions into the atmosphere. The method comprises preheating and sifting glauconitic sand, subsequently dividing said sand with the aid of magnetic separation into a magnetic and a nonmagnetic fraction, grinding the magnetic fraction, mixing the ground magnetic fraction with water to form a plastic compound, granulating said compound, drying the granules produced, crushing said granules, sifting the latter with granules of the required granulometric composition being extracted, calcining and cooling said granules, and packaging the finished product. The technical result is an increase in the sorption capacity and sorption volume of the granulated sorbent owing to the use of the magnetic fraction of the glauconite as the binder.</p> |
