项目摘要

This proposal pertains to the development of an economic and technically viable process for capture and sequestration of carbon dioxide via a carbonation reaction in magnesium-rich tailings for Canada Nickel Company's nickel mining project. The objective of the project is to remove, capture and sequestrate 100% of the carbon dioxide produced in this future mining operation, and even potentially consider further carbon dioxide removal from the atmosphere with the excess capacity of the operation. The tailings of this mining project, similar to some other mining projects and operations in Canada and around the globe, are rich in magnesium minerals. Those minerals have strong affinity for carbon dioxide adsorption, i.e. reaction with carbon dioxide. Therefore, it is possible to fix a substantial amount of carbon dioxide in the tailings site of the future mining plant, as solid carbon dioxide containing minerals. The focus of this project is the development of a processing flowsheet, its optimization and modelling of carbon dioxide capture and sequestration capacity of the Canada Nickel Company nickel mining project. This research stands to benefit Canada as it highlights industry-led green technology incentivized by the Federal carbon pricing model. It will serve as a proof of concept for carbon sequestration in full-scale mines and motivate other Canadian operations to pursue similar technologies.

该提案涉及开发一种经济且技术上可行的工艺，通过加拿大镍公司镍矿项目的富镁尾矿中的碳酸化反应来捕获和封存二氧化碳。该项目的目标是去除、捕获和封存未来采矿作业中产生的 100% 的二氧化碳，甚至可能考虑在作业产能过剩的情况下进一步从大气中去除二氧化碳。与加拿大和全球其他一些采矿项目和作业类似，该采矿项目的尾矿富含镁矿物。这些矿物质对二氧化碳吸附即与二氧化碳反应有很强的亲和力。因此，可以将大量二氧化碳固定在未来采矿厂的尾矿场中，作为含有固体二氧化碳的矿物。该项目的重点是加拿大镍业公司镍矿项目的加工流程的开发、二氧化碳捕获和封存能力的优化和建模。这项研究将使加拿大受益，因为它强调了联邦碳定价模型激励的行业主导的绿色技术。它将作为大规模矿山碳封存的概念证明，并激励加拿大其他企业寻求类似技术。
