KOLWEZI, DEMOCRATIC REPUBLIC CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Executive Co-Chair Robert Friedland and President Marna Cloete are pleased to provide an update on preliminary test work conducted to improve copper recovery at the Kamoa-Kakula Copper Complex.
Ivanhoe Mines’ Founder and Executive Co-Chairman, Robert Friedland commented:
“Despite the Phase 1 and 2 concentrators exceeding the nameplate recovery rate, the grade of copper in Kamoa-Kakula’s tailings is still much higher than that of most major copper mines globally. This is a direct consequence of Kamoa-Kakula being the highest-grade major copper mine globally. However, we are leaving a significant amount of copper behind… copper that this planet so desperately needs right now for our energy transition.
“If we can recover this copper, the production profile following the Phase 3 expansion could be in excess of 700,000 tonnes per annum. Not only would this provide additional revenue and cash flow, but also it would reduce even further our tailings footprint.
“We are targeting total copper recoveries in the mid-nineties from this breakthrough as well as from the other concurrent workstreams. Our experienced team, with a proven track record of execution and delivery, are leaving no stone unturned to improve the efficiency of extraction from this incredible endowment.”
Kamoa-Kakula is the highest-grade major copper mine; further improvement in recoveries can result in significantly increased copper production
In 2022, Kamoa Copper’s process engineering team, together with a number of internationally recognized external metallurgy specialists, initiated work to investigate ways to economically recover additional copper units from the tailings stream of the Phase 1 and 2 concentrators.
During 2022, the Kamoa-Kakula Copper Complex milled approximately 7.1 million tonnes of ore at an average feed grade of 5.5% copper, producing 333,497 tonnes of copper in concentrate. Based on the metallurgical recovery of 86% copper, which was in line with design parameters, in excess of 50,000 tonnes of copper was not recovered into concentrate and diverted to the tailings storage facility, or used underground as backfill. The grade of Kamoa-Kakula’s tailings in 2022 averaged approximately 0.8% copper. For comparison, the average head grade of the copper mines globally was 0.6% in 2022, according to Bank of Montreal (BMO) research. See Figure 1.
Kamoa-Kakula’s ore contains fine-grained copper sulphides (chalcocite), which to fully liberate from the host rock requires grinding of the ore to fine particle size. Grinding rock to an ever-finer particle size is exponentially energy intensive. During the original flowsheet development, a trade-off was struck between recovery and energy intensity. The Phase 1 and 2 concentrator design has primary grinding to 80% passing less than 53 microns (-53 μm). This grind size is already significantly finer than most copper concentrators globally.
Copper recoveries from the Phase 1 and 2 concentrators have improved year-to-date, averaging 87.1% during H1 2023, and periodically achieving as high as 90%. However, any further sustained improvement in copper recoveries presents a significant opportunity to generate additional revenue at Kamoa-Kakula.

To date, 13 workstreams with separate entities have been initiated leveraging various technologies to improve copper recoveries. This includes the recently announced collaboration with I-Pulse Inc., as announced on June 15, 2023.

More recently, promising preliminary results were received from work conducted by Expert Process Solutions (XPS) of Falconbridge, Canada. XPS has worked with Kamoa-Kakula since project inception, conducting metallurgical testwork during the study phases before construction. Therefore, XPS has a high degree of experience working with both the Kamoa and Kakula deposits.
Preliminary test results indicate a significant improvement in total copper recoveries can be achieved
XPS was reappointed for a dedicated scope of work focused on grinding and reprocessing the tailings stream from the Phase 1 and 2 concentrators. Initial preliminary results indicate that with a feed grade of less than 1% copper, approximately 65% of the contained copper can be recovered from the tailings stream. The results generated a saleable concentrate with a grade of approximately 40% copper that could be processed on-site at the 500,000 tonnes-per-annum direct-to-blister flash copper smelter that is currently under construction. For comparison, the copper concentrate grade from the Phase 1 and 2 concentrators is currently approximately 50%.
The test program consisted of fine-grinding the tailings stream to a particle size of 80% -12 μm, before conventional flotation, thickening and filtration.

Additional copper recovery from tailings stream increases production, revenue and cash flow, improving overall economics
DRA Global of Johannesburg, South Africa, a company that has also been working with Kamoa-Kakula since project inception, was appointed to design a process based on the initial metallurgical results. DRA conducted a desktop study on the construction of a dedicated, stand-alone processing plant to treat the entire tailings stream from the Phase 1 and 2 concentrators. The circuit design for the stand-alone processing plant uses conventional technology, such as high-intensity grinding mills and Jameson cells (Glencore-owned technology) for the flotation, as well as additional thickening capacity.
DRA has also determined preliminary, high-level capital expenditure and operating costs associated with the construction and operation of the tailings recovery plant and the economics are significantly positive.
Further metallurgical test work by XPS and engineering by DRA will continue to verify and optimize the process design, with the view to advancing the project to an investment decision.
Concurrently, the other 12 workstreams will continue to explore the most suitable option that will be implemented. The workstreams, among others, consist of conventional leaching, glycine leaching, ion exchange, as well as pulsed-power technology by I-Pulse Inc. to crush rock. Pulsed power technology consists of high-intensity bursts of electrical energy that can quickly and efficiently shatter rocks and mineral ores by targeting the tensile weakness of rocks.

刚果民主共和国科卢韦齐 — 艾芬豪矿业 (TSX: IVN; OTCQX: IVPAF) 执行联席董事长罗伯特·弗里兰德 (Robert Friedland)和总裁玛娜·克洛特 (Marna Cloete) 欣然公布，卡莫阿-卡库拉 (Kamoa-Kakula) 铜矿提高铜回收率的初步试验取得可喜进展。
艾芬豪矿业创始人兼执行联席董事长罗伯特·弗里兰德评论道：“尽管 I 期和 II 期选厂综合回收率已经超越设计指标，卡莫阿-卡库拉的尾矿品位仍远高于全球大多数大型铜矿，主要是因为卡莫阿-卡库拉原矿品位是全球最高的。然而，我们的尾矿中仍然残留大量的铜；铜金属资源正是全球迈向能源转型迫切所需的。”
“如果我们能够回收这些尾矿中的铜，III 期投产后的年产量将可达到70万吨以上，不但能够创造更多收入和现金流，还可进一步减少公司的尾矿足迹。”
“我们的目标是要通过这项突破和其它同步举措，使综合回收率超过90%。我们的团队经验丰富，在执行和交付方面成绩斐然。卡莫阿-卡库拉铜矿蕴藏着无与伦比的资源，我们的团队正竭尽所能，力求提高资源的综合利用率。”
卡莫阿-卡库拉是全球品位最高的超大型铜矿，进一步提高回收率将大幅提高产量
2022年，卡莫阿铜业的选矿团队与多个国际知名的研究单位合作，探索以具有经济合理性的技术从I 期和 II 期尾矿回收铜金属。
2022年，卡莫阿-卡库拉铜矿共处理约710万吨矿石，平均入选品位5.5%，产铜33.3万吨。以铜选矿回收率86%计算 (与设计指标一致) ，超过5万吨铜未能回收而进入尾矿库或用于井下回填。卡莫阿-卡库拉2022年的尾矿平均铜品位约0.8%。BMO的研究显示，2022年全球铜矿的原矿平均铜品位为0.6% (见图 1)。
卡莫阿-卡库拉矿石中主要的含铜矿物为细粒辉铜矿，需要磨至很小的粒度才能从矿石中完全解离，而磨矿至超细粒度是能量高度密集的作业环节。因此，最初的流程图设计，在回收率和能量密集度之间优选最佳平衡。I 期和 II 期选厂设计的一段磨矿细度为80%通过-53微米，与全球大多数铜选厂相比更细。
2023年至今，I 期和 II 期选厂的铜回收率得到改善，2023年上半年的平均回收率为87.1%，期间更一度达到90%。铜回收率的持续上升趋势，将为卡莫阿-卡库拉提高经济效益创造重要契机。

迄今为止，公司启动了13项不同技术路线的选矿试验，探索如何提高铜回收率，其中包括2023年6月15日公布与I-Pulse有限公司达成的合作，以及中国有研科技集团、紫金矿冶设计研究院开展的选矿试验服务。
加拿大Expert Process Solutions (XPS) 公司最近开展的试验取得乐观的初步结果。XPS长期与卡莫阿-卡库拉紧密合作，在矿山建设之前的研究阶段就为项目提供了选冶试验技术服务。因此，XPS与卡莫阿和卡库拉两座矿山都有相当的合作经验。
初步试验结果表明综合回收率可以得到显著提升
我们再次聘用XPS开展 I 期和 II 期尾矿的磨矿和再处理试验工作。初步试验结果表明，在入选品位低于1%的情况下，仍可回收尾矿中约65%的铜以生产含铜约40%的铜精矿，未来可在卡莫阿正在建设的50万吨/年一步炼铜冶炼厂进行加工处理。与之可对比的是，I 期和 II 期选厂的铜精矿品位约50%。
试验包括将尾矿磨至80%通过-12微米后，再进行常规的浮选、浓密和压滤工序。

从尾矿再回收铜金属，有助于提高产量、收入和现金流，大幅改善整体经济性
南非约翰内斯堡的DRA Global公司自矿山启动开发工作以来一直与卡莫阿-卡库拉紧密合作，受聘以初步选冶结果为基础开展流程设计研究。DRA已完成一项案头工作，为卡莫阿铜业设计一座独立选厂，专门处理来自 I 期和 II 期选厂的尾矿。尾矿选厂将采用传统技术，包括浮选工艺使用的高强度磨机和Jameson浮选机 (嘉能可拥有的技术) ，并扩大浓密处理能力。
DRA已针对尾矿再回收设施的建设和运营开展了相关技术经济研究，包括高水平的初步资本性开支和运营成本测算，结果显示经济效益非常可观。
XPS 后续开展的选冶试验及 DRA 的工程设计，将继续用于验证和优化项目的工艺设计，力求推进项目发展以推进投资决策。
同时，另外12项试验将继续研究以探索最合适的技术方案。包括常规浸出、甘氨酸辅助浸出、离子交换，以及I-Pulse公司的脉冲功率技术。脉冲功率技术在短时间内释放高强度能源，针对岩石拉伸强度的弱点，能够快速高效地粉碎岩石和矿石。
