The mineralogy and sintering behavior of limonitic nickel laterite with high iron and low nickel and silica was studied to offer technical support for producing ferronickel through sintering-blast furnace route. The mineralogy results showed that the main phases in this kind of nickel laterite are goethite (FeO(OH)), gibbsite (Al(OH)3) and
Types of nickel laterites . Two kinds of lateritic nickel ore have to be distinguished: goethite-limonite types and nontronitic clay types. Limonite type laterites (or oxide type) contain 1-2% Ni bound in goethite which is highly enriched due to very strong leaching of magnesium and silica. Beneath this zone nickel silicate ore can be formed
Canada Sherritt Company utilizing wet-process technology to treat laterite-nickel ore has been approved. 4th, laterite-nickel ore could produce nickel oxide, sulfided nickel and iron nickel, etc. intermediate product, while sulfided nickel and nickel oxide could be used for nickel refining plant which could solve the lack supply of sulfided nickel.
2011年1月1日 pirometallurgical means. The nickel laterite ore was dehydrated in a laboratory scale sintering pot in this study. The dehydration mechanism was studied by using the thermo-gravimetric (TG)...
2016年3月4日 Iron soars to 59.21% from initial grade of 47.62% Fe. Nickel also increased 0.42%. Sintered products were upgraded using magnetic and gravity separations. Upgraded product yielded an assay of 62.23% Fe and the Chromite is increased by 5.93% Final concentrates yield for Nickel and Iron combined is 60% and for Chromite is at 8%.
2021年10月24日 Nickel laterite ore is used to produce nickel metal, predominantly to manufacture stainless steel as well as nickel sulfate, a key ingredient in the batteries that drive electric vehicles. Nickel laterite production is on the rise
2019年6月11日 Sintering: A Step Between Mining Iron Ore and Steelmaking By Alison Cestari 06.11.2019 The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3).

2021年1月6日 The Bureau of Mines has developed a hydrometallurgical process to recover nickel and cobalt from lateritic ores. The nickel and cobalt are selectively reduced and then extracted by an oxidizing ammonia-ammonium sulfate leach. During reduction the goethite and hematite are converted to magnetite, metallic iron, and taenite (ferronickel alloy).
