the chemical phase of cobalt ore is usually divided into There are three phases: sulfide phase, oxide phase and refractory gangue phase: This document is included in "Rock and Mineral Analysis" (Fourth Edition)) Volume III 43:7 Nickel Ore On the basis of phase analysis and 44:6 cobalt ore phase analysis, the selective separation conditions of each mineral phase were optimized; for cobalt and nickel They have similar geochemical and physicochemical properties, similar mineral assemblages and dissolution characteristics, and co-associated characteristics, and established a systematic and complete system for the first time: A chemical phase analysis method system for the simultaneous analysis and determination of nickel and cobalt in copper-nickel sulfide ores; for the physical chemistry of copper-nickel sulfide ores For the first time, the magnetic mineral phase in copper-nickel sulfide ore was used as a chemical phase, and the magnetic phase was further divided into magnetic sulfide phase, magnetic The non-sulfide phase improves the application purpose and use value of the chemical phase analysis results; the application of modern analysis and testing technology to copper nickel sulfide For the chemical phase analysis of ores, a method based on inductively coupled plasma emission spectrometry was established, supplemented by atomic absorption spectrometry for the determination of nickel: The chemical phase analysis and detection system of cobalt and cobalt can improve the accuracy and work efficiency of chemical phase analysis results: This document was created for Nickel (Cobalt) Provide technical support for ore exploration, development and utilization: The issuer of this document draws attention to the fact that when declaring compliance with this document, it may involve the relevant magnetic Selective separation of nickel and cobalt in the magnetic sulfide phase, magnetic non-sulfide phase, non-magnetic sulfide phase, oxide phase and soluble gangue phase and refractory gangue phase use of related patents: The issuing authority of this document has no position regarding the veracity, validity and scope of this patent: The patent holder has committed to the issuing authority of this document that he is willing to cooperate with any applicant on reasonable and non-discriminatory terms and conditions Next, negotiate the licensing of patents: The patent holder's statement is on file with the issuing authority of this document: Relevant information can be obtained through Get in contact with: Name of patent holder: Shaanxi Provincial Institute of Geology and Mineral Resources Experiment: Address: No: 100 Yanta North Road, Xi'an City, Shaanxi Province: Please note that in addition to the above patents, some content of this document may still involve patents: The issuer of this document is not responsible for identifying patents Responsibility: Chemical Phase Analysis Method of Copper Nickel Sulfide Ore Determination of Nickel and Cobalt Contents in Six Mineral Phases Caution --- Personnel using this document should have practical experience in formal laboratory work: This document does not address all possible security issues question: It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations:1 ScopeThis document describes the physical and chemical selective separation - inductively coupled plasma optical emission spectrometry (ICP-OES) or atomic absorption spectrometry The magnetic sulfide phase, magnetic non-sulfide phase, sulfate phase, nonmagnetic sulfide phase, oxidized phase and Chemical phase analysis method for nickel and cobalt content in soluble gangue phase and refractory gangue phase: This document is applicable to magnetic sulfide phase, magnetic non-sulfide phase, sulfate phase, non-magnetic Determination of nickel and cobalt content in 6 mineral phases including sulfide phase, oxide phase, soluble gangue phase and refractory gangue phase: The detection limit and measurement range of the analytical method are shown in Table 1 and Table 2: Table 1 Detection limits and measurement ranges of copper-nickel sulfide ore chemical phase analysis methods (ICP-OES determination) mineral phase Method detection limit for nickel a w(Ni)/10-2 Measuring range of nickel b w(Ni)/10-2 Method detection limit for cobalta w(Co)/10-2 Measuring range of cobalt b w(Co)/10-2 Magnetic sulfide phase 0:0116 0:0348~5 0:0007 0:0021~0:2 Magnetic non-sulfide phase 0:0084 0:0252~2 0:0005 0:0015~0:02 Sulfate phase 0:0039 0:0117~1 0:0003 0:0010~0:03 Nonmagnetic sulfide phase 0:0469 0:141~5 0:0021 0:0063~0:1 Oxidized phase and soluble gangue phase 0:0097 0:0291~1 0:0009 0:0027~0:03 Insoluble gangue phase 0:0026 0:0078~1 0:0005 0:0016~0:01 a The method detection limits of nickel and cobalt in the 6 mineral phases are based on the proposed chemical phase selective separation process for actual samples with lower content, tested by 7 experiments The laboratory used ICP-OES to perform 4 repeated measurements, and calculated the detection limits of nickel and cobalt in each phase with 3 times the standard deviation; the detection limit measurement results were weighed The sample volume is 0:5g, and the volume of the measured sample solution is 25mL: b The measurement range takes 3 times the detection limit of the method as the lowest lower limit, and considers the possible highest content of nickel and cobalt in different phases of the actual sample as the upper limit of determination: Table 2 Detection limit and measurement range of copper-nickel sulfide ore chemical phase analysis method (AAS determination) mineral phase Method detection limit for nickel a w(Ni)/10-2 Measuring range of nickel b w(Ni)/10-2 Method detection limit for cobalta w(Co)/10-2 Measuring range of cobalt b w(Co)/10-2 Magnetic sulfide phase 0:0165 0:0495~5 0:0007 0:0021~0:2 Magnetic non-sulfide phase 0:0091 0:0273~2 0:0008 0:0024~0:02 Sulfate phase 0:0033 0:0099~1 0:0005 0:0015~0:03 Nonmagnetic sulfide phase 0:0413 0:124~5 0:0031 0:0093~0:1 ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 42630-2023_English be delivered?Answer: Upon your order, we will start to translate GB/T 42630-2023_English as soon as possible, and keep you informed of the progress.
