The Terresis plant in Ólvega ( Spain ) focuses

exclusively on producing magnesium

oxide - based solutions for animal nutrition ,

and came on stream in February 2025 ,

marking the culmination of a project

completed in record time . Every stage

of its development from design through

construction to commissioning was precisely

managed with close attention to detail .

Three factors made all the difference :

full control of the production chain ,

demanding safety standards and rapid

implementation capability . To this list ,

Ólvega Plant Manager Anyul Iriarte is keen

to add : “ The dedication , commitment

and passion of all the people involved in

the project . ” Here ’ s our interview with her .

Anyul Iriarte / The f irst thing to say is that

this has been an atypical project , because

we ’ ve taken a greenf ield site and created

an operational plant in just six months .

Our ambition was clear from the outset

to make Ólvega a driver for growth and a

showcase for the magnesium oxide based

products used in animal nutrition Our

integrated model is another unique feature

From extraction in our mines to processing

in our plants we have full control of the

entire process from raw material collection

right through to the f inished product

Lastly Ólvega is unusual for the degree of

automation in its grinding and blending

What are the

special features

unique to Terresis

Ólvega ?

From extraction in

our mines to processing

control of the entire process

from raw material collection
