ENFI

What ENFI does

ENFI (中国恩菲工程技术有限公司, China ENFI Engineering Technology Co., Ltd.) is a state-owned engineering design and EPC (Engineering, Procurement, Construction) services provider headquartered in Beijing, China, founded in 1953 and operating as a wholly-owned subsidiary of China Minmetals Corporation (中国五矿集团), a central state-owned conglomerate. The company specializes in non-ferrous metals mining and metallurgy, environmental protection, energy engineering, and industrial digitalization, serving mining and metallurgy enterprises, municipal and environmental clients, and government entities across more than 14 countries in Asia, Africa, and South America.

Its technology stack combines proprietary metallurgical process technologies (186㎡ third-generation fluidized bed roaster for zinc smelting at 200,000 t/y single-series capacity, oxygen bottom-blown lead smelting, side-blown immersion pool smelting for tin, RKEF for nickel laterite) with the self-developed MIM+ industrial internet platform that integrates data from nearly 100,000 monitoring points across 20+ intelligent equipment systems. The platform underpins ICC intelligent combustion control for waste incineration (98%+ auto-investment rate), digital twin engineering management, predictive maintenance (fault detection 3-5 days earlier than manual), and AI-driven multi-objective optimization across copper, zinc, and aluminum processes. ENFI holds CMMI5 certification, has won 7 China Patent Awards (1 Gold, 1 Silver), and leads development of five national standards covering tungsten metallurgy, digital delivery, lithium extraction metallurgy, concentrator design, and mine energy-saving design.

The business model centers on project-based EPC general contracting (lump-sum and cost-plus), fixed-fee engineering design services, equipment supply and technology licensing, and recurring revenue from BOT/operations subsidiaries with 30-year waste-to-energy concessions. Customer acquisition occurs through formal tendering, direct enterprise sales, and strategic partnerships with international mining corporations (MOUs signed with Rio Tinto and BHP Invent). The customer base spans four business segments: non-ferrous metals mining and metallurgy (primary, including copper, lead, zinc, nickel, specialty metals), environmental protection and waste management, tourism infrastructure (ropeways for sites including Mount Tai and Mount Huang), and industrial digital transformation. Notable customers include Henan Yuguang Group, Anshan Iron and Steel Group, China Molybdenum (TFM), Shengda Resources, Yunnan Copper, and WCS (Simandou), with landmark projects including the world's largest zinc smelting single-unit facility in Xinjiang (560,000 t/y zinc), the Eritrea Asmara copper polymetallic mine (4 million t/y ore processing), and the Guinea Simandou iron ore project (120 million t/y design capacity).

1. EPC General Contracting: ENFI serves as EPC (Engineering, Procurement, Construction) general contractor for large-scale mining, metallurgy, and environmental engineering projects. Revenue is generated through project-based lump-sum or cost-plus contracting for design, procurement, and construction management services. Examples include the Xinjiang Huowuqi 60kt/y lead-zinc smelting project and the Indonesia CNI nickel iron RKEF project.
2. Engineering Design and Technical Consulting: ENFI provides specialized engineering design services for non-ferrous metals mining, metallurgy, environmental protection, and infrastructure projects. Revenue is generated through fixed-fee design contracts. The company holds national-level qualifications as an engineering design institution.
3. Equipment Supply and Technology Licensing: ENFI supplies core process equipment (e.g., 186㎡ fluidized bed roasters, RKEF electric furnaces, side-blown smelting systems) and licenses proprietary technologies to clients. Revenue is generated through equipment supply contracts and technology licensing fees.
4. BOT/Operations (Subsidiaries): ENFI operates subsidiaries including Xiangyang ENFI Environmental Energy (waste-to-energy, BOT model, 30-year concession) and other environmental treatment facilities, generating recurring revenue from waste processing fees and electricity generation sales.
