Leaching characteristics of an iron-rich siltation pond waste and its viability in indirect carbon sequestration

Abstract

An iron-rich siltation pond waste from a nickel mining site was used as the starting material for indirect carbonation. Iron-leaching experiments were conducted on the mining waste, using HCl as the leaching agent at varying HCl concentrations, reaction times, and reaction temperatures. It was found that the extraction efficiency of iron (EEI) increased when a more concentrated HCl solution was used and at higher temperatures. Based on the EEI trend over time, a layer of silica gel layer forms around the sample, hindering further iron extraction. A maximum EEI of 93.79% was observed.
