摘要
小行星因其赋存丰富的矿产资源而成为未来战略资源储备的重点目标,镍作为关键战略金属具有重要的价值。本文系统梳理了小行星镍资源的分布与赋存特征,重点评估了近地小行星中高镍含量的C型与M型小行星的资源开发潜力,并分析了小行星独特的空间环境特征,包括微重力、极端温度、超高真空条件与地质不确定性等。基于镍资源的赋存状态与小行星极端环境约束,提出并探讨了适用于原位开发的多种技术路径,包括羰化法、磁选预富集法、碳热还原法及直接熔炼法,并对4种方法进行了比较分析,为小行星镍资源的原位开发与利用提供了理论支撑。
Asteroids have become key targets for future strategic resource reserves due to their abundant mineral resources.Nickel,as a critical strategic metal,holds significant value.In the paper,the distribution and occurrence characteristics of nickel resources in asteroids were systematically summarized,focused on evaluating the resources development potential of nickel-rich C-type and M-type asteroids among near-Earth asteroids,and the unique spatial environmental characteristics of asteroids was analyzed,including microgravity,extreme temperatures, ultra-high vacuum conditions, and geological uncertainties. Based on the occurrence state of nickel resources and the constraints of the extreme asteroid environment, the multiple technical paths suitable for in-situ development were proposed and discussed, including the carbonylation method, magnetic separation pre concentration method, carbothermal reduction method, and direct smelting method. A comparative analysis of these four methods was also conducted, which provides theoretical support for the in-situ development and utilization of nickel resources in asteroids.
