National mineral processing and metallurgical research council Mintek has unveiled its latest technological acquisition – the AMAZEMET rePowder ultrasonic atomisation and alloy development machine.

Said to be highly advanced equipment, and the only one in South Africa, this device was presented to delegates from industry, including Anglo American Platinum and international industry partners, during a recent event.

The rePowder machine is able to process nearly any material, ranging from alloys with low melting points to those with high melting thresholds.

This device produces high-quality metal powder with outstanding particle size distribution and flowability to a level of quality historically imported by South Africa.

Its capacity to process small quantities is highlighted to represent a considerable advancement for the industry, which allows processing of expensive precious metals.

Commenting on the acquisition, Mintek CEO Dr Molefi Motuku highlighted that it is an indication of Mintek’s commitment to establishing essential infrastructure for industrial development.

“This acquisition represents a significant leap forward in our mission to empower South Africa's industries with cutting-edge technology as guided by our strategy.

“It addresses a longstanding need for high-quality metal powder production and exemplifies Mintek’s unwavering dedication to fostering innovation in mineral processing and will be of great value to our partners and industry at large,” he acclaimed.

Speaking at the tour, Mintek Physical Metallurgy head Joseph Moema emphasised the utility of the machine for the industry.

“This is pivotal for Mintek, as it will benefit a wide array of industries, including glass, biomedical, aerospace and jewellery. For instance, in the biomedical field, high-quality metal powder can be used to produce orthopaedic implants, dental prosthetics and even drug delivery systems.

“These applications rely on precision and material quality, areas where our technology excels. It aligns with our strategy to foster minerals-based industries in South Africa by providing value-adding technologies and services, thereby expanding the minerals-based value chain,” he averred.

“We believe there are many prospects for forging a mutually beneficial partnership with industry across a diverse portfolio of metals,” Moema added.
