TL;DR: In 2008, the nitric acid pressure leaching (NAPL) technology was invented and developed to treat laterite ores in China as mentioned in this paper, and a pilot plant with an annual processing capacity of 330,000 tons of dry ores was assembled and tested.
Journal ArticleDOI
Selective pressure leaching of Fe (II)-rich limonitic laterite ores from Indonesia using nitric acid
TL;DR: In this article, the selective extraction of nickel and cobalt over iron from an Indonesian limonitic laterite was investigated using nitric acid pressure leaching (NAPL), where the major minerals were goethite and magnetite, and the content of the divalent iron was as high as 7.06%.
Journal ArticleDOI
Screening and reduction roasting of limonitic laterite and ammonia-carbonate leaching of nickel–cobalt to produce a high-grade iron concentrate
TL;DR: In this paper, a limonitic laterite from the Philippines was screened to remove some silicate minerals and then treated via reduction roasting-ammonia leaching, and the optimal conditions of reduction Roasting of screened ore (Ore I) were determined through a series of tests.
Journal ArticleDOI
Effect of activation pretreatment of limonitic laterite ores using sodium fluoride and sulfuric acid on water leaching of nickel and cobalt
TL;DR: In this paper, the effect of activation pretreatment of limonitic laterite ores using sodium fluoride and sulfuric acid on water leaching of nickel (Ni) and cobalt (Co) over iron at atmospheric pressure was investigated.
Journal ArticleDOI
Solid-State Metalized Reduction of Magnesium-Rich Low-Nickel Oxide Ores Using Coal as the Reductant Based on Thermodynamic Analysis
TL;DR: In this article, a solid-state metalized reduction of magnesium-rich low-nickel oxide ore using coal as a reductant was studied based on thermodynamic analysis, where the major constituent minerals of the ore were silicates and goethite.
