Tanaka plans Indonesia precious-metals investment, industry group says
Talks with the Industry Ministry are scheduled for 2 November 2026, with the investment value still undetermined and chemical regulations to be discussed.
Japan’s Tanaka Precious Metals plans to invest in precious-metals processing in Indonesia and is due to discuss the proposal with the Industry Ministry on 2 November 2026, according to Arief Budiman, deputy chairman of the Indonesian Jewellery Producers Association (APPI).
Speaking to reporters on 28 October 2026, Arief said no investment value had been determined. Regulations affecting chemical raw materials still needed discussion with the government, including restrictions on potassium cyanide.
APPI is coordinating with the ministry to clarify investment requirements for prospective investors, he said. Any investment would depend on compliance with applicable rules, including waste requirements.
Arief said the proposed industry could process gold into materials for electronics and automotive manufacturing, rather than jewellery alone. Products discussed included potassium gold cyanide, used in plating electronic components, and bonding wire, a fine wire connecting internal parts of semiconductor components.
He said much of this processing currently takes place outside Indonesia, including in Taiwan, and argued that establishing it domestically would add value to Indonesian gold output. Arief estimated production from mining companies in Indonesia at about 120 tonnes and expressed confidence that a domestic precious-metals industry could absorb all of that output.
