PT.Huafei Nickel Cobalt Co., Ltd. was established in May 2021. It is jointly built by Huayou Cobalt, Tsingshan Holding Group and EVE Energy Co., Ltd, with a total investment of about 2.1 billion US dollars. The project consists of ore washing, chrome separation, leaching, acid production and other processes and supporting facilities; the product is nickel cobalt hydroxide, equivalent to 120,000 t/a nickel, 15,000 t/a cobalt; by-product 500,000 t/a chrome concentrate mine.PT.Huafei Nickel Cobalt Project is located in Indonesia Wedabay Industrial Park (PT.IWIP), Halmahera Island, North Maluku County, Maluku, Indonesia. Huafei Indonesia wet process project adopts the world's most advanced third-generation laterite nickel ore High Pressure Acid Leaching (HPAL) process and auxiliary technology to extract nickel and cobalt hydroxide MHP from laterite ore, and extract nickel, cobalt and manganese by synchronous coupling Metal, seamless connection with the ternary battery material. Fully implement the design concept of "green + ecology", integrate non-ferrous metal smelting and chemical refining, the capital investment per unit product and the production cost per unit product are far lower than similar projects in the world, with high technical threshold, high automation control, ultra-low cost production. The outstanding characteristics of export and ultra-low carbon emissions. The process has the advantages of short process flow, low energy consumption, energy saving and environmental protection, and has a good application prospect.
