Production Units in Italy

MINERALI INDUSTRIALI: mines and factories in Italy.

Eight production units, for guaranteeing absolute regularity, which is maybe the most appreciated quality in the ceramic industry. Raw materials are extracted exclusively from its own large-size mines.

In Masserano, in the province of Biella, production is destined for the sectors of ceramic sanitary ware, ceramic and refractory paint factories, paints and varnishes with the supply of ventilated products; Engineered-stone and construction with supply of quartz and feldspar grains; ceramic tiles with local feldspar supply. The grinding treatments are carried out with high compression cylinders (MI patent machine).

In the former ACDAL mine in Lozzolo, in the province of Vercelli, production is mainly dedicated to the white and red body tiles sector and to the E-stone sector (mainly for kitchen tops). The mine has been active since the early 1900s, when the approximately 300 employees worked on hand-digging the most famous clays.

The production unit of Santa Severa, in Rome, is a small mine, unique in Italy, of a very precious material: kaolin. Here, kaolins with the celebrated whiteness for sanitary ware and ceramic glazes are obtained.

The Verbania site was born in 1992 with the name of ECOMIN (Mining Ecology); in this plant Minerali Industriali produces sodium potassium feldspar starting from white and pink granite, intended for the ceramic tile, sanitaryware and glass industry. It does so by developing a happy environmental intuition, that is, by recovering and treating granite processing waste as ornamental stone: thanks to a cutting-edge mining treatment it obtains, starting from an otherwise unusable material, an excellent product for porcelain stoneware tiles, sanitary ware. and glass. ECOMIN thus reclaims the historic and centuries-old landfills in the Lake Maggiore area, close to Monte Orfano and Monte Camoscio. In this way, the Company on the one hand avoids the opening of new mining sites and, on the other hand, heals dangerous and aesthetically unpleasant situations due to mining landfills made up of materials accumulated in bulk.

Mine and Factory of Boca (NO)

In the rhyolite mine of Boca, in the province of Novara, today about 150,000 tons per year are produced for the ceramic tile industry; the extracted material is treated in the annexed crushing and screening plant. The preventive geological mapping of the reservoir and the constant mixing activity in the plant allow to keep the characteristics of the finished product constant over time.

Quarry and Factory of Sondalo (SO)

Minerali Industriali is particularly proud of the Sondalo quartz mine, in the province of Sondrio, opened in the mid-1960s with “open pit” excavation methods; since the mid-90s the business has moved underground with undoubted landscape and environmental advantages. The extracted mineral has a silica content of over 99%: about 60,000 tons per year are extracted for the grinding plants of Bernate Ticino (MI) and Cacciano di Masserano (BI) for use in the E- industry. stone, sanitary ceramics, ceramic paint factories and as a raw material for the ferroalloy sector.

Factory of Bernate Ticino (MI)

Minerali Industriali produces ventilated quartz at the Bernate Ticino plant, in the province of Milan. Here the incoming material is crushed, dried, deferred and then finely ground for a total production capacity of about 70,000 tons per year. Subsequently the product is ensiled ready to be loaded on tank trucks or packed in big bags or sacks and sent to the customer. Reference sectors: E-stone, ceramic sanitary ware, ceramic paint factories, paints and varnishes.

Finally, in the municipality of Malesco, in Finero (VB), there is an olivine mine with a high MgO content with characteristics of high interest for the foundry sector.

Factory of Ravenna 

In the Ravenna production unit, acquired in 2021 and launched in 2022, Minerali Industriali produces quartz, feldspar, feldspar and ventilated sands for the ceramic sanitaryware, ceramic paint factories, paints and varnishes and E-stone sectors; dried silica sands for the glassworks and foundries sector; in addition to managing a series of grinding for third parties on related products. The location of the plant is central to the national territory and located on the routes of northern Europe as well as strategic on the port of Ravenna; This position will allow the use of raw materials arriving by land and by ship, moreover delivery to end customers will benefit from logistical optimizations related to the flows of goods in transit. The Ravenna production unit is able to produce over 80,000 tons / year with the 2 lines recently started while the construction of a third line is being studied that would bring the production capacity to exceed 120,000 tons / year.

MAFFEI SARDA SILICATI: business, production and market.

This company was founded on 1 April 2009 from the merger through acquisition of the two Sardinian entities being part of Minerali Industriali.

MAFFEI SARDA SILICATI is characterised by a strong focus on technology, along with the priority of its targets relating to premium production.
It meets the needs of the most demanding companies: feldspathic sand for clear and crystal glass, feldspar for glass-making and ceramic industries, kaolinitic clay for ceramic.
The Company exploits soda feldspar deposits (albitite) in Central Sardinia, more specifically in the area of Orani – Ottana (Nuoro); it also exploits feldspathic sand in the area of Ossi-Florinas and treats it in the factory of Ossi, province of Sassari. Lastly, it exploits soda feldspar in Buddusò (Olbia-Tempio Pausania).

Produced minerals are used in the ceramic tile industry (single firing and porcelain stoneware) in the district of Sassuolo, and in the sanitary ware industry in the district of Civita Castellana (sanitary ware). Products are also exported, especially to Spain, to the ceramic industry district of Castellon de la Plana.

Production Unit of Orani
Orani production unit consists of one main opencast mine (Ispaduleddas), and other secondary opencast mines, along with a nearby treatment plant for extracted minerals, located in Ciarumannu. The unit also includes a logistic-administrative department with offices, warehouses and quality control laboratory.
Feldspar extraction from the Ispaduleddas mine began in 1990, from a previously existing mining site that had been abandoned.
These opencast mines are exploited through selective mining, by blasting or by using mechanical means, according to rock compactness. Ciarumannu treatment plant started operating in 1992. It consists of two crushing sections (primary and secondary) where the mineral is processed mechanically by crushing, cleaning and screening.
The obtained marketable mineral is a granule with grain-size of 0-6 mm. In 1999 an optical sorting machine (Sorter) was also used in Orani production unit: it was the first time in the world that laser technology was being applied to feldspar production. For further information, please click here.

Production Unit of Ottana
The production unit of Ottana has been operating since 2000. It consists of various opencast mines and one treatment plant located in Badu e Carru.
Moreover, it hosts a logistic-administrative department, with offices and warehouses. The dry-process production consists of three crushing sections (first, second and third) where the mineral is mechanically processed by crushing and screening; finished product is a granule with grain-size of 0-6 mm.
Open cast mines are exploited through selective mining mainly by mechanical means and, only in few cases, by blasting. For further information, please
