The global market is becoming increasingly complex, and in this context, trust and transparency are more important than ever. At PROMINDSA, we firmly believe that knowing the origin of what you buy is key to ensuring product quality and sustainability.
That’s why we control our entire value chain — from mineral extraction in our own mines to the transformation process in our plant and the delivery of the final pigment or desulphurising agent — supported by 100% mechanical processes and certified traceability for every batch.
Controlled origin: our own mines and exclusive operation
At PROMINDSA, we are the sole operator of our mines, which allows us to guarantee a certain and verifiable origin for all our raw materials.
This level of control sets us apart in a market where transparency and traceability are increasingly valued. From extraction to transformation, every mineral is tracked, eliminating the risk of unverified sources or mixed materials that could compromise product purity.
Transformation process: 100% mechanical and fully traceable
Once extracted, the mineral is processed in our own facilities using fully mechanical methods, without the need for additives or synthetic components.
These processes ensure that our pigments and desulphurising agents preserve the natural properties of the mineral and meet the highest purity and performance standards required by industrial applications.
Continuous analysis and certification
To guarantee consistent quality, we carry out daily analytical controls throughout every production stage. Each batch is accompanied by technical documentation and laboratory tests certifying its composition and verified origin.
As a result, every product we deliver carries more than quality — it carries the assurance of guaranteed origin and the trust built on more than a century of mining experience.
Transparency and trust: our way of working
At PROMINDSA, we believe that sustainability and responsibility begin at the source. That’s why our commitment is based on verifiable facts: our own mines, controlled processes, independent testing, and transparent communication with our customers. We don’t just produce — we prove it with facts.
Frequently asked questions about origin and traceability
Why is it important to know the origin of a pigment or desulphurising agent?
Because it ensures the product has not been mixed or altered with lower-quality materials and that it complies with environmental and technical standards.
What does it mean that PROMINDSA operates its own mines?
It means we are the exclusive operator of the mines where our minerals are extracted, ensuring complete traceability from the source to the final product.
How is each batch’s traceability certified?
Through analytical tests, technical documentation and process records that verify the composition and provenance of every material we supply.
