承德大庙钒钛磁铁矿伴生钴的赋存状态和富集机制

Key Points

• Cobalt primarily substitutes iron in pyrite crystals, indicating its complex presence within the ore.
• Significant variations in cobalt content were found, ranging from 0.73% in dense iron-titanium ores to 0.21% in sparsely impregnated ores.
• The study employs auto mineral analysis and laser ablation inductively coupled plasma mass spectrometry to detail cobalt's geochemical behavior.
• High-temperature, high-pH sulfur-rich fluids facilitate cobalt enrichment, highlighting important mineral formation conditions.
