Malaysia’s new 4N refinery brings high-purity gold refining home

Malaysia’s first precious metal refinery capable of producing gold with a purity of 99.99% (4N) is under construction at Batu Kawan Industrial Park, Penang, according to reporting from PenangToday. The joint venture between Japan’s TANAKA Precious Metal Technologies and Malaysia’s MEP Enviro Technology aims to begin operations in the first quarter of 2029. The plant’s first phase carries an investment of RM35 million and will focus on gold and potassium gold cyanide (PGC) for the electronics and semiconductor industries.

The new plant is designed to refine gold recovered from Malaysia’s fast-growing semiconductor and electronics waste streams. Until now, MEP concentrated precious metals in Malaysia but sent them abroad, mainly to TANAKA’s facilities in Japan, for the final high-purity stage. This new facility will complete the refining process domestically, returning 4N gold and other precious metal products directly into the local manufacturing supply chain.

For physical precious metals buyers, the key change is provenance and supply chain transparency. With most refining previously done outside the country, tracing gold’s journey from waste to new industrial use required international coordination. Processing and refining inside Malaysia means both the recovery and high-purity stages can be verified more easily, a step that matters for industries where traceability, compliance and supply chain security are national priorities.

According to PenangToday, gold is a critical input for the semiconductor industry, used to plate and connect intricate chip components. The nearby presence of a 4N gold refinery makes it practical for manufacturers to source locally recovered, locally refined gold, closing the loop for recycled metal within Malaysia’s borders.

We think the more useful question is what this means for buyers and users of Malaysian precious metals beyond the spot price. When a refinery’s recovery, refining and output stages are all under local rules and oversight, customers may have more direct evidence about where metal comes from and how it was handled. That clarity may be valued in industrial supply chains and by buyers concerned with sourcing metal responsibly. However, not all details of audit and inspection processes are public, so full visibility cannot be assumed without further disclosure from the companies involved.

For now, the main shift is that some gold recycled from Malaysia’s electronics industry will no longer leave the country for final refining. Instead, it will be processed domestically and can re-enter the local or regional supply chain as high-purity material, providing new options to manufacturers and, potentially, buyers of physical gold products who prioritize local provenance.
