On December 30, 2021, the "Key Technologies for Clean Extraction and Efficient Utilization of Nickel, Cobalt and Scandium", a key special project of China under the national key research and development plan "Development and Utilization of Strategic Mineral Resources" in the "14th Five-Year" Plan passed the state review and was officially approved for initialization. The project was jointly applied by ten scientific research institutions, universities and enterprises, including China ENFI Engineering Co., Ltd., the Institute of Process Engineering of the Chinese Academy of Sciences, and Lygend Resources & Technology Co., Ltd.
This special project is divided into five sections.
Lygend Resources undertakes the research tasks of for two sections, i.e. optimizing the sulfuric acid leaching process of laterite nickel ore and developing a super large reactor, as well as the separation of sulfur containing iron slag calcium/iron and the preparation technology and equipment of high-grade iron concentrate powder.
The overall goal of the key special project "Strategic Mineral Resource Development and Utilization" is to focus on national resource security and major strategic needs, target major scientific and technological problems in the exploration, development and utilization of strategic mineral resources, achieve theoretical breakthroughs in green development, high-value utilization, intelligent integration, and other aspects of mineral resources, and realize technical breakthroughs in a number of major core common key technologies and equipment, establish several demonstration bases for the development and utilization of strategic mineral resources, provide scientific and technological support for building a high-quality resource guarantee system, and cultivate and form a high-level research team.
China's nickel and cobalt resources are relatively scarce, and the efficient development and utilization of overseas resources of laterite nickel ores is a major national strategy.In December 2018, Lygend Resources & Technology Co., Ltd. and Harita Group from Indonesia jointly invested in the construction of a pressurized sulfuric acid leaching project of laterite nickel ore on the OBI Island in Indonesia. The project relies on the high-quality laterite nickel ore resources on the OBI Island and the talent team of Lygend Resources Co., Ltd. and the technological advantages of leading the world to produce high-purity nickel sulfate and cobalt sulfate products required by new energy vehicles. Moreover, it is in line with China's "Belt and Road" development strategy and also meets the requirements of Indonesia's national strategic investment projects.

The project was completed and put into operation in May 2021 under the severe interference of COVID-19, and the production of the high-pressure acid leaching Series 1 reached its capacity target in July of that year, creating a historical record of the shortest construction time of similar projects in the world and the shortest time to reach the production capacity target. The products are sold well in the Chinese market, and the project has become the first nickel high-pressure acid leaching project completed and reached its capacity in Indonesia and has a huge social impact and economic benefits in China and Indonesia.
Lygend Resources attaches great importance to scientific research and technological investment. Since the launch of the OBI nickel-cobalt project, a series of new processes, equipment, and materials have been successfully developed and applied based on bold innovation, scientific experiments, and sufficient argumentation, laying a solid foundation for the smooth construction and rapid production and compliance of the project Phase I. Based on the experience of the first phase of the project, Lygend Resources continues to increase its efforts in scientific research and research. With the support of national funds and research institutes, it has invested RMB 30 million to support the research on process and equipment optimization.
The purpose of the project on optimizing the sulfuric acid leaching process of laterite nickel ore and developing a super large reactor is to further optimize the high-pressure acid leaching (HPAL) process and equipment of laterite nickel ore, develop super large core equipment, and achieve the goal of reducing investment intensity, improving production efficiency, and reducing production costs to improve quality and efficiency. The purpose of the research and development of sulfur containing iron slag calcium/iron separation and high-grade iron powder preparation technology and equipment is to address the long-term problem of resource waste and high disposal costs caused by the direct discharge of iron containing tailing from the high-pressure acid leaching of laterite nickel ores and to construct a complete set of technologies for efficient extraction, short-term utilization, tailing resource utilization, and collaborative extraction of nickel cobalt iron scandium resources from laterite nickel ores through in-depth research on key technologies for efficient and clean extraction and comprehensive utilization of laterite nickel ore resources.
The successful application of the "Key Technologies for Clean Extraction and Efficient Utilization of Nickel, Cobalt, and Scandium" Project highlights the important strategic position of nickel and cobalt resources in national development, as well as the leading technological advantage of Lygend Resources in the high-pressure acid leaching of laterite nickel ores, and also reflects Lygend Resources' development philosophy of emphasizing clean extraction and efficient utilization of resources, actively responding to carbon peaking and carbon neutrality. Lygend Resources will work with partners to carry out various research projects, further enhance its technological advantages in this field, and promote its sustainable and high-quality development path.
