On June 6, 2025, Ju Anran, Senior Manager of SMM's aluminum category, and Liu Xinyi, Analyst of SMM's aluminum category, led a delegation to PT Well Harvest Winning Alumina Refinery (hereinafter referred to as "WHW"). They held in-depth discussions and exchanges with WHW's management at its Jakarta office.

Company Profile

Established in 2015, WHW is the first Smelter Grade Alumina (SGA) alumina refinery in Indonesia. The project was jointly invested by China Hongqiao Group Co. Ltd. (holding 56% stake), PT Cita Mineral Investindo Tbk, a subsidiary of Indonesia's Harita Group (holding 30% stake), Winning Investment (HK) Co., Ltd., and Shandong Weiqiao Aluminum & Power Co., Ltd., with a total investment of approximately $1.3 billion. As of 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. The first phase, 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 wharf, and employee 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 sides explored core issues including WHW's existing production capacity, the composition of raw material and electricity costs, 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.
