Dec 22, 2016 China produced about 290,000 tonnes of nickel metal in 2016 from laterite ore imported from the Philippines, compared with an estimated 355,000 tonnes of nickel metal in 2015, Yang qin, vp of Beijing Dinghejintong Economy and Trade Co, one of Chinas top nickel ore trading companies, said at a nickel and stainless steel forum in Beijing in mid-December.
The economic and environmental advantages of AeRD for processing of laterite tailings comprise no requirement for an anoxic atmosphere, 1.8-fold less acid consumption than for AnRD, as well as nickel and cobalt recovered in a ferrous-based pregnant leach solution (PLS), facilitating the subsequent metal recovery.
Apr 19, 2016 Abstract. Based on the process of coal-based self-reduction and melting separation at high temperature, it was investigated that the effect of process factors on the reduction of iron and nickel oxide, the metal yield and the nickel content in ferronickel about the laterite nickel ore, was from Philippines and contented low nickel, high iron and aluminum.
Good ore must be clear, heavy, and firm of grain, free from earth, stone, and all traces of any other kind of metal. (1540, translated by Smith and Gnudi 199066) Beneficiation , or making good, is a metallurgical practice of millennia, and is a means of artificially increasing the metal content of a mineral. Using physical
Laterite ore is one of the important sources of nickel (Ni). However, it is difficult to liberate Ni from ore structure during reduction roasting. This paper provided an effective way for a robust recovery of Ni from laterite ore by H2 reduction using sodium thiosulfate (Na2S2O3) as a promoter. . It was found that a Ni content of 9.97% and a Ni recovery of 99.24% were achieved with 20 wt ...
Mar 24, 2021 Chinas laterite nickel ore imports from the Philippines are expected to drop 20.4% to 35 million wmt in 2020 from 2019, as deliveries have been hit hard by the COVID-19 pandemic early in the year, said Lingying Zhang, senior nickel analyst at SMM.
Recent laterite projects commonly vary at this stage, some operating a nickel refinery to produce pure metal, while some produce an intermediate nickel hydroxide (or even sulfide) product for export to a refinery. An alternative process for laterite ores is to use the Caron process, based on high temperature
solid-state bloomery process, universal in the Pre-Medieval world excepting China (Craddock 1995), requires a very high quality of ore with an iron content of 60wt% or more. The technical requirement for the production of an iron-rich siliceous slag in addition to the iron metal itself, dictates the use of an ore providing sufficient
Jun 26, 2019 HPAL is a process used to extract nickel from laterite ore, with its main advantage being the ability to process low grade nickel laterite ores and its high and separate recovery of nickel and cobalt.
One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.

Laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. It forms in tropical and subtropical regions where the climate is humid. Lateritic soils may contain clay minerals but they tend to be silica-poor, for silica is leached out by waters passing through the soil.
