Calcination of low-grade laterite for concentration of

In this study, a low-grade nickeliferous laterite ore was first calcinated and then processed by using a wet magnetic separator in order to recover nickel. Since, the ore contains both Ni and Fe, the calcination of laterite is effective in altering the crystalline structure of Fe species and therefore its magnetic properties, which in turn enable the selective concentration of nickel by magnetic separation that is an easy and

Calcination of low-grade laterite for concentration of

2010-3-1  In this study, the concentration of nickel from low-grade laterite was carried out by using a simple, cost-effective and environmentally-friendly process such as the wet magnetic separation. Since, the laterite ore usually contains Fe which has magnetic properties, the concentration of Ni is not an easy task. In order to enable the selective concentration of nickel by magnetic separation, the calcination of laterite was carried out prior to the magnetic

Upgrading low nickel content laterite ores using

2012-5-20  According to previous research, nickeliferous concentrates with nickel content of 5.1% and a nickel recovery of 98.8% could be produced from LN laterite ore by selective reduction and magnetic separation process when the reduction was conducted at 1250 °C for 60 min (Li et al., 2010). During the calcination, reduction of wustite was suppressed by the addition of silica through the formation of fayalite, allowing greater proportions of iron to be removed during the magnetic
