Metso Outotec to deliver two sulfuric acid plants to Uzbekistan

Metso Outotec Corporation’s press release on December 13, 2022, at 2:00 p.m. EET

Almalyk Mining and Metallurgical Company (AMMC) has awarded Metso Outotec an order for the delivery of two sulfuric acid plants to be built for AMMC’s zinc roasting facility in Almalyk, Uzbekistan. The value of the order is approximately EUR 70 million, and it is booked in Metals’ fourth-quarter orders received.

Metso Outotec’s scope of delivery includes the design and delivery of Planet Positive equipment for two gas cleaning and sulfuric acid plants, which will process all off-gases from the zinc roasters into industrial-grade sulfuric acid. In addition, Metso Outotec will deliver utility facilities, such as a common cooling tower system and a common air compressor system.

The two plants to be delivered by Metso Outotec will be identical and will replace AMMC’s existing facilities for gas cleaning and sulfuric acid production. The plants will improve operational efficiency and reliability and significantly reduce the facilities’ environmental impact. The sulfuric acid plants are expected to be operational by the end of the second half of 2025.

“We are extremely pleased that Almalyk has again selected us as the partner for providing gas cleaning and sulfuric acid technology. Metso Outotec’s advanced Planet Positive gas cleaning and sulfuric acid plant solution will improve the environmental performance of AMMC’s metallurgical operations,” says Hannes Storch, Vice President, Metal and Chemical Processing at Metso Outotec.
