FTIR analysis of water structure and its influence on

2013-7-10  The flotation chemistry of soluble salts has been studied for many decades. In this work, the flotation behavior of arcanite (K 2 SO 4) and epsomite (MgSO 4 7H 2 O) with both the cationic collector, dodecylamine hydrochloride (DAH), and the anionic collector, sodium dodecyl-sufate (SDS), has been studied. The results show that K 2 SO 4 can be floated with both the cationic and anionic ...

Aqueous mineral carbonation of ultramafic material: a

2021-2-7  Ex situ aqueous mineral carbonation of ultramafic mining waste is an evolving technology for the CO2 sequestration from small- to medium-scale emitters. The mineral ores or mine wastes of associated ultramafic mineralogy are a suitable feedstock for mineral carbonation. The aqueous mineral carbonation at ambient temperature is motivating and attractive from an energy-saving perspective.
