2022

Resources and output

In 2022, anticipated economic resources of bentonitic raw materials amounted to 2,896.81 thousand tonnes. The resources increased in the result of documentation of a new deposit – Drugnia Rządowa II with resources equal 15.30 thousand tonnes, located in Kielecki county. In the deposit there were bentonitic clays documented and practically “pure” bentonites as the accompanying raw material to lithothamnion limestones of the Tortonian age. Currently, there are 2 deposits with an exploitation concession issued located in Dolnośląskie Voivodeship (Jawor-Męcinka and Krzeniów) and 1 deposit with such a concession located in Podkarpackie Voivodeship (Dylągówka-Zapaday). In 2022, the exploitation of bentonites was not carried out.

2018

Bentonites are clayey rocks originated in the result of the transform (bentonitization) process of a volcanic glass occurring in the pyroclastic rocks such as tuffs and tuffites. The bentonites are built mainly of the smectite minerals group (with the minimum montmorillonite content of 75%) accompanied by other clayey minerals and relicts of a pyroclastic material. Related to the bentonites are bentonitic clays containing, along with smectite minerals, the larger amount of other clayey minerals.

Rocks rich in smectite group minerals have some common features which decide on the rocks usage such as: an ability to swell, their susceptibility to the dispersion of water, a high plasticity, their easy absorption of cations and organic substances from water solutions, their ability to form the thixotropic suspensions. Thanks to these features, there are more than 40 ways of utilization of these rocks, i.a.: in a foundry industry (as a component of foundry mass), in a chemical industry (for the production of fillers, sorbents, catalysts, paints etc.), in a paper industry, a pharmaceutical industry, a cosmetic industry, a ceramic industry, in the engineering and hydro-technical works (a soil stabilization, waterproof screens, sealings), in an agriculture and as a component of drilling fluid. Most of bentonites in Poland are used traditionally in the foundry industry, the drilling and in a new, strongly developing hygienic sorbents market (for animals).

Primary bentonites in Poland (it means almost monomineralic montmorillonitic rocks with a small admixture of other minerlas) occur very seldom. More common are various bentonitic clays with a relatively high content of non-clayey minerlas. The group of bentonitic raw materials contains bentonitic weathering covers of basalts in the Lower Silesia region, bentonitic clays in the Upper Silesia region, bentonitic clays of the southern fringes of the Holy Cross Mts., bentonitic clays in the Carpathian Mts.

In 2018, anticipated economic resources of bentonitic raw materials amounted to 2,883.43 thousand tonnes. There are two deposits with an exploitation concession issued – Jawor-Męcinka and Krzeniów, both located in Dolnośląskie Voivodeship. The output of the bentonites mantle rock of the basalt tuffs has been carried out only from Krzeniów deposit and for more than 10 years it has been maintaining within the range of 0.45-2.80 thousand tonnes per year. In 2018 the output was equal 0.56 thousand tonnes (Table 2).

2017

Primary bentonites are produced in the result of a weathering of extrusive and pyroclastic rocks and usually display a parent rock structure. In turn, bentonite clays originate due to the redeposition of bentonite material and often yield fairly large admixture of foreign mineral components. Bentonite clays which form a weathering mantle developed on the Jawor-Męcinka and Krzeniów basalts were explored as mineral deposits accompanying those of basalts.

Nevertheless, in 2017 the exploitation has not been carried out from any of these deposits.
