Effect of Binary Basicity (CaO/SiO2) on Selective Reduction of Lateritic Nickel Ore
Selective reduction methods are being developed to process lateritic nickel ore to produce nickel with high content with low temperature or energy consumption. This research was carried out to study the effect of binary basicity (CaO/SiO 2 ) in the lateritic nickel ore's selective reduction process. The lateritic nickel ore with 1.38% Ni and 38.2% Fe content was used in this study. The reduction was conducted at 1150°C for 60 minutes in a muffle furnace with 10 wt.% additives of sodium sulfate, bituminous coal as reductant, and calcium oxide addition to modify its binary basicity. The results showed that the nickel grades generates from the 0,1 basicity due to the breakage of magnesium, iron, and nickel silicate into metallic iron and nickel. However, the next increase of basicities decreased the nickel grade due to the formation of a high melting point compound. lateritic nickel ore, selective reduction, binary basicity, reductant, additive.
期刊介绍：
Periodico di Mineralogia is an international peer-reviewed Open Access journal publishing Research Articles, Letters and Reviews in Mineralogy, Crystallography, Geochemistry, Ore Deposits, Petrology, Volcanology and applied topics on Environment, Archaeometry and Cultural Heritage. The journal aims at encouraging scientists to publish their experimental and theoretical results in as much detail as possible. Accordingly, there is no restriction on article length. Additional data may be hosted on the web sites as Supplementary Information. The journal does not have article submission and processing charges. Colour is free of charges both on line and printed and no Open Access fees are requested. Short publication time is assured.
Periodico di Mineralogia is property of Sapienza Università di Roma and is published, both online and printed, three times a year.
