On June 6, 2025, Allison Ju, Senior Manager of SMM's Aluminum Overseas Sales Team, and Cathy Liu, SMM's Aluminum Analyst, led a delegation to PT Well Harvest Winning Alumina Refinery (hereinafter referred to as "WHW"), where they held in-depth discussions with WHW's management at its Jakarta office.
Company introduction
Established in 2015, WHW is Indonesia's first Smelter Grade Alumina (SGA) alumina refinery. The project was jointly invested by China Hongqiao Group Co., Ltd. (holding a 56% stake), PT Cita Mineral Investindo Tbk (a subsidiary of Indonesia's Harita Group, holding a 30% stake), Winning Investment (HK) Co., Ltd., and Shandong Weiqiao Aluminum & Electricity Co., Ltd., with a total investment of approximately $1.3 billion. By year-end 2020, the paid-in capital had reached $1.2 billion. The plant is located in Sungai Tengar District, Mekar Utama Village, Ketapang County, West Kalimantan Province, covering an area of over 1,000 hectares. Phase I, with an annual production capacity of 1 million mt, commenced operations in June 2016 and was expanded to 2 million mt/year in 2022. It is equipped with a steam power plant, an international-standard port, and staff dormitory areas. Its products not only meet the demand of local aluminum smelters in Indonesia but are also exported to major markets such as China, India, and Malaysia.
During the discussions, both parties explored core issues including WHW's existing production capacity, the cost structure of raw materials and electricity, and the promotion of green and low-carbon production technologies. Through communication, both sides enhanced their understanding, further solidified the foundation of mutual trust, and reached preliminary intentions in potential areas such as technological cooperation, raw material exchange, and joint R&D. This visit not only laid a solid foundation for establishing a long-term and stable cooperative relationship in the future but also opened up new opportunities for jointly promoting the green and sustainable development of Indonesia's alumina industry.
