PROMINDSA

What PROMINDSA does

PROMINDSA (legal name: PRODUCTOS MINERALES PARA LA INDUSTRIA S.A.) is a Spanish industrial minerals company founded in 1973 and headquartered in Zaragoza, operating as a wholly-owned subsidiary of GRUPO MARCO since 2005. The company extracts iron oxide and hydroxide ore from its owned Santa Rosa de Tierga mine (in operation since 1913) in the Sierra del Moncayo, and processes the raw mineral through micronization into finished inorganic pigments sold under the MICRONOX brand. The portfolio spans the full color spectrum (Black, Blue, Brown, Green, Marigold, Micaceous Iron Oxide, Red, Yellow) plus specialty grades such as MIO 88 with 95.7% hematite content, serving decorative and industrial paints, anticorrosive coatings, construction materials (cement, mortars, concrete, asphalt, ceramics, glass, roof tiles, bricks), fertilizers, and foundry/steel applications.

The second core line is MICRONOX BIOX (MICRONOX ON16), launched in 2016 as a mixture of iron oxides-hydroxides and functional oxides engineered for hydrogen sulfide (H2S) capture inside anaerobic biogas and biomethane digesters, generating iron sulfide byproducts with fertilizer value. The company documents 95-100% H2S removal efficiency for this application. Both product lines run on 100% renewable energy under Spanish Guarantees of Origin certification.

PROMINDSA operates a direct B2B industrial sales model with quote-based pricing, packaged in big bags and paper bags, distributed to manufacturers and biogas producers in more than 70 countries with no public pricing transparency. The company is small by employee count (22) but globally distributed, and has accumulated regulatory credentials including ISO 9001, REACH, CE marking, carbon footprint certification, and an EcoVadis Gold Medal (2023) placing it above 93% of peers in the metallurgical mining sector. Named enterprise customers include Hempel and Lanxess; the company's 2023 all-time sales record coincided with its 50th anniversary and triggered new capacity investments.

Core offering

PROMINDSA extracts, transforms, develops and supplies iron oxide and iron hydroxide minerals and inorganic micronized pigments from its Santa Rosa de Tierga mine in Spain. Its commercial offering comprises two lines: the MICRONOX Pigments range (iron oxide pigments across black, blue, brown, green, marigold, micaceous/MIO, red and yellow, sold to paints, coatings, construction, fertilizers, glass and industrial customers) and MICRONOX Biox (MICRONOX ON16), a specialty iron oxides-hydroxides product used by biogas and biomethane producers for hydrogen sulfide desulfurization in anaerobic digestion reactors.

Product overview

PROMINDSA offers two core product lines: Micronox Pigments and Micronox Biox. Micronox Pigments is a comprehensive portfolio of inorganic micronized iron oxide and hydroxide pigments available in multiple color variants (Black, Blue, Brown, Green, Marigold, MIO, Red, Yellow) serving diverse industries including construction, paints, fertilizers, glass, and industrial coatings. Micronox Biox (specifically ON16) is a specialized product for biogas and biomethane desulfurization, using iron oxides-hydroxides to capture hydrogen sulfide in anaerobic digestion processes. The company extracts minerals from its Santa Rosa mine and operates from Spain, supplying products to over 70 countries globally.

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• BASF (Colors & Effects): BASF produces inorganic pigments, including iron oxides, as part of its broader industrial chemicals and coatings materials portfolio. Overlaps with PROMINDSA in pigment chemistry and end markets but competes from a vastly larger, diversified chemical platform rather than as a pure-play iron oxide specialist.
• Vibrantz Technologies (formerly Ferro): Vibrantz (formed from Ferro's divestitures) supplies performance pigments and colorants, including iron oxides, to coatings, construction, plastics, and industrial markets. Comparable as an incumbent with iron oxide exposure but with a much broader pigments and specialty materials portfolio beyond iron oxides.
• Sun Chemical: Sun Chemical is a major global pigments and inks producer, including iron oxide pigments used in coatings, plastics, and construction. Comparable as a broad incumbent in inorganic pigments but with a much wider product portfolio (organic pigments, dyes, printing inks) and substantially larger scale.

Direct peers

• Lanxess (Bayferrox): Lanxess operates Bayferrox, one of the world's largest iron oxide pigment businesses, supplying synthetic and natural iron oxides to paints, construction, plastics, and coatings. Directly comparable to PROMINDSA in product category (iron oxide pigments) and end markets, though at much larger scale and broader geographic footprint.
• Pure Air Solutions: Pure Air Solutions provides biological and chemical hydrogen sulfide removal systems for biogas and biomethane plants, including iron-oxide-based dosing alternatives. Directly comparable to PROMINDSA's MICRONOX BIOX line on the biogas desulfurization use case and target customers (biogas/biomethane producers).
• Harold Scholz: Harold Scholz is a German producer of natural and synthetic iron oxide pigments serving paints, construction, plastics, and specialty applications. Directly comparable to PROMINDSA on product (iron oxide pigments), European base, and B2B industrial sales motion.
• Cathay Industries: Cathay Industries is a global iron oxide pigment manufacturer offering red, yellow, black, brown, and specialty pigments for construction, coatings, plastics, and rubber. Closely comparable to PROMINDSA on product (iron oxide pigments), end-market exposure, and global B2B distribution model.
• Venator Materials: Venator produces iron oxide pigments under its Pigments & Additives segment for coatings, construction, plastics, and specialty applications. A direct competitor to PROMINDSA in iron oxide pigments with overlapping end markets, particularly construction materials and industrial coatings.
