Study of the Migration Characteristics of Iron Ion in Laterite in Water

Abstract:

The migration characteristics of iron ions in laterite in water can reflected by change characteristics of iron ion concentration in water solution. Its migration ability depends on itself features of laterite and the effect of external environment. The results show that, the migration ability of iron ion in laterite were weakened with increasing of compaction energy and extending of immersion times, were strengthed with increasing of moisture content and temperature. The effect of compaction energy is least, the effect of temperature is maximum, the effect of moisture content is between them. Its migration process is that iron ion of adsorption in laterite particles surface were dissolved and migrated into process of the water solution. Its migration mechanism can explained from water environmental balance and temperature balance and ion concentration balance. The results changed the migration characteristics of iron ion in laterite at different influencing factors.
