Petroleum coke as reductant in co-reduction of low-grade laterite ore and red mud to prepare ferronickel: Reductant and reduction effects
文献摘要：
Petroleum coke is industrial solid wastes and its disposal and storage has been a great challenge to the environment. In this study, petroleum coke was utilized as a novel co-reduction reductant of low-grade laterite ore and red mud. A ferronickel product of 1.98wt％ nickel and 87.98wt％ iron was obtained with 20wt％ petroleum coke, when the roasting temperature and time was 1250℃ and 60 min, respectively. The corresponding recoveries of nickel and total iron were 99.54wt％ and 95.59wt％, respectively. Scanning electron microscopy–energy dis-persive spectrometry (SEM–EDS) analysis showed metallic nickel and iron mainly existed in the form of ferronickel particles which distrib-uted uniformly at a size of approximately 30 μm with high purity. This study demonstrated that petroleum coke is a promising reductant in the co-reduction of laterite ore and red mud. Compared to other alternatives, petroleum coke is advantageous with reduced production cost and high applicability in anthracite-deficient areas.
