Indonesia CNI Nickel Iron Contracting Project

Supply equipment: single-phase -3150/33 (9 units)
Supplier: Zhongbian Group Shanghai Transformer Co., Ltd

The CNI Nickel Iron Project is located on Sulawesi Island, Indonesia. It is a joint venture between China's ENFI and Indonesia's large engineering construction enterprise PT PP for the EPC general contracting of the first phase of the project. The project adopts the company's RKEF technology, including the company's core expertise in laterite nickel ore electric furnace melting technology, low heat loss high-temperature roasting sand transportation technology, etc. The annual ore processing capacity is about 872500 tons (dry basis), and the production of nickel iron is about 57300 tons/year (including 22% nickel). The project consists of five major parts: RKEF smelting plant area, smelting plant auxiliary facilities, public utilities, office and living areas, and external facilities. The first phase of the design scale is one 72MVA rectangular nickel iron electric furnace production line, which was launched in mid June 2022.

CNI Corporation is a local private enterprise in Indonesia, with abundant nickel ore resources in Southeast Sulawesi Province. As a representative of the Indonesian government's encouragement of nickel ore smelting policies and acceleration of downstream nickel industry chain production, the CNI nickel ore development project has been included in Indonesia's national strategic project list. After the project is fully completed, it will process 3.78 million tons of dry ore annually and produce nickel iron with a grade of 22%, equivalent to an annual production of 55600 tons of nickel metal. One phase of the project includes a 72 megavolt ampere electric furnace RKEF production line independently innovated by China Enfi, with an annual output of 13900 tons of nickel metal. After completion and operation, it will become the first rectangular large electric furnace nickel iron production line in Indonesia's smelting field. CNI will also build a high-pressure acid leaching (HPAL) smelter to produce 40000 tons/year of nickel cobalt hydroxide (MHP) containing nickel metal for the production of new energy batteries.
