Indonesia: Suvo Strategic Minerals has reported successful laboratory tests in collaboration with Makassar State University (UNM) in Indonesia, transforming nickel slag into a ‘high-strength, low-cost and low-carbon’ cement, according to The Sydney Morning Herald. The trials used slag from PT Huadi Nickel-Alloy Indonesia's operations in South Sulawesi, achieving a compressive strength of 37.5MPa after seven days. The company is now looking to conduct further testing and will provide the results to PT Huadi, with the aim of forming a partnership for the commercialisation of low-carbon cement using nickel slag.
Aaron Bank, executive chair of Suvo Strategic Minerals, said “We are excited to have commenced this workstream in Indonesia testing the byproduct of one of the country’s largest mining companies, with our ultimate goal being to manufacture an environmentally-friendly and low-carbon alternative to Portland cement. Achieving up to 37.5MPa after only seven days is an outstanding first round trial result for the company and could provide an entry into a large industry.”
