Methods for chemical analysis of laterite nickel ores - Part 10.Determination of calcium, cobalt, copper, magnesium, manganese, nickel, phosphate and zinc content - Inductively coupled plasma atomic emission spectrometry1 ScopeThis part of YS/T 820 specifies the method for determining calcium, cobalt, copper, magnesium, manganese, nickel, phosphate and zinc content in laterite nickel ores. This part applies to the simultaneous determination of calcium, cobalt, copper, magnesium, manganese, nickel, phosphorus and zinc contents in laterite nickel ores. The range of determination is as shown in Table 1. Table 1 -- Range of determination (mass fraction)2 Normative referencesThe following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard. YS/T 820.24-2012 Methods for chemical analysis of laterite nickel ores - Part 24.Determination hygroscopic moisture content - Gravimetric method Element Range of determination / %3 Summary of methodsThe sample is decomposed by hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid. The salts are dissolved by hydrochloric acid.4 ReagentsUnless otherwise stated, only reagents identified as superior grade and the distilled or deionized water or water of comparable purity are used in the analysis. 4.1 Hydrochloric acid (ρ1.19 g/mL). 4.2 Hydrochloric acid (1 + 1). 4.7 Calcium standard stock solution. WEIGH 1.2486 g of calcium carbonate (wCaCO3 ≥ 99.99%, which is dried in advance at 105 °C ± 5 °C and cooled in a desiccator to room temperature); PLACE it in a 300 mL beaker; ADD 20 mL of water; MIX it uniformly; COVER the watch glass; carefully ADD hydrochloric acid (4.2) to dissolve calcium carbonate; ADD another 30 mL of hydrochloric acid (4.2); BOIL it to remove carbon dioxide; REMOVE and COOL it to room temperature; USE water to rinse the watch glass and beaker’s wall; 4.9 Copper standard stock solution. WEIGH 0.2000 g of metal copper (wCu ≥ 99.95%); PLACE it in a 300 mL beaker; COVER the watch glass; slowly ADD 40 mL of nitric acid (4.4) to dissolve it at low temperature; DRIVE out the nitrogen oxide; REMOVE and COOL it to room temperature; USE water to rinse the watch glass and beaker’s wall; TRANSFER it into a 1000 mL volumetric flask; USE water to dilute it to the mark; MIX it uniformly. 1 mL of this solution contains 0.2 mg of copper. 4.11 Manganese standard stock solution.
