Processing of Nickel Laterite Ores on the Rise, Most laterite ore deposits are made up of both limonite (iron rich) and saprolite layers, with the thickness of each layer varying significantly across different deposits Limonite, which accounts for nearly double the amount of saprolite available globally, is more amenable to processing via hydometallurgical techniques, while saprolites are ,Hydro, However the additional reduction of iron oxide lowers the Ni grade (albeit normally increasing the Ni recovery to some extent) and can result FeNi with Ni contents well below the normal specification of 20% (ie typically between 5 and 15%) These low Ni grades are typical of nickel pig iron ,Reduction process of low, In direct reduction processes of iron ore and nickel, the Boudouard reaction is important because the gaseous reducing agent that is formed is CO (g) This can be seen in Figure 4, in which the formation of CO (g) and its stability is shown to occur above 1000 °CSEPTEMBER 2014 QUARTERLY REPORT 30 October 2014, Oct 30, 2014· An internal study into nickel laterite processing through the use of direct reduction technology is ongoing along with discussions with local companies with processing experience SNPDC and Pelican Staff reviewed several new projects in the Philippines including iron ore, iron ,Effect of Sodium Sulfate on Preparation of Ferronickel ,, The nickel laterite used in this study was obtained from Philippin The main chemical composition of the raw nickel laterite is shown in Table 1 The content of Ni and total iron grade (TFe) was 18 mass% and 179 mass%, respectively It can be observed that the sample has a high content of silica, magnesia, alumina and water (includes:.
