sorbentmaterial selectively to metallic impurities and its method of application

摘要

The invention concerns an adsorbent material selective with respect to metal pollutants, characterised in that it consists of particles with predetermined size grading less than 3 mm, of a feldspar ore of natural origin: its mode expressed in mass percentages is as follows: albite 50 %, anorthite /=6 %, orthoclase 10 %, quartz 20 %, with a percentage of Na2O /=6 %.
