Scottish engineering firm Weir Group has won a £36m order to supply energy-saving technology for an iron ore processing plant in Ukraine.
Under the deal with Ferrexpo, Weir will supply equipment such as high-pressure grinding rolls (HPGRs) and screens.
Swiss-based Ferrexpo is one of the world's largest exporters of iron ore pellets to the steel industry.
According to Weir, its HPGRs cut energy consumption by more than 40%, compared with traditional mining technologies.
The equipment will be designed and built by a Weir subsidiary in the Netherlands.
Ferrexpo is planning to increase output from its operations in Ukraine from 32 million tonnes per year to more than 80 million.
Weir Group chief executive Jon Stanton said: "This is a great endorsement from one of the world's leading miners of the key role Weir's technology has in making mining operations more efficient and sustainable."
Glasgow-based Weir switched its focus to mining and infrastructure after selling its oil and gas division to Caterpillar in a £314m deal last year.
Meanwhile, the group reported strong growth in orders in the first quarter as conditions in mining markets continued to improve on the back of high commodity prices.
In a trading update, it said there was a 67% increase in original equipment (OE) orders.
Weir said demand was strongest in North America, Central Asia and Africa, but more subdued in Asia-Pacific and South America.
