General information and occurrence

Feldspar raw materials are the natural accumulations of various types of feldspar and feldspar-quartzitic rocks rich in alkali (Na₂O + K₂O equal at least 6.5%). The deposits of feldspar raw materials occur in Dolnośląskie and Małopolskie Voivodeships. These raw materials include leucogranites occurring in the various regions of the Lower Silesian area i.e. in the vicinities of Strzeblów and in Izera Mts. (Kopaniec vicinities). The feldspar raw materials are also represented by feldspars of porphyry varieties of the Karkonosze granites from the vicinities of Karpniki, Maciejowa and Góra Sośnia in the Jelenia Góra Basin (Sudety Mts.). Other raw materials of that type occurring in the Silesian-Cracow region are: potassium trachyte from Siedlec and Kwaczała arcose from Wygiełzowa.

The feldspar is one of the major raw materials in the ceramic industry. It is used in the form of powders and feldspar-quartz aggregates in the manufacture of the high-class porcelain and bone china, ceramic tiles, sanitary ceramics, enamel materials and in the glass industry. The feldspar raw materials are also recovered as by-products in the quarrying of granites rich in potassium feldspar.

Feldspar raw materials deposits are presented on the map.

Resources and output

Table 1 shows the current state of exploration and development of feldspar raw material deposits.

Table 1. Feldspar raw materials – million tonnes

The anticipated economic resources of feldspar raw materials decreased by 0.01 million tonnes due to the exploitation and in 2022 amounted to 139.04 million tonnes. There was only 1 deposit exploited: Pagórki Wschodnie whereas the exploitation from the Stary Łom deposit was on hold. Still, in spite of a valid exploitation concession, the output from the Karpniki deposit (abandoned in 2011) was not resumed.

The anticipated economic resources of the exploited deposits account only for 4.16% of the total anticipated economic resources. The majority of anticipated economic resources are the resources within non-exploited deposits. The economic resources of the exploited deposits decreased by 0.02 thousand tonnes due to the exploitation and amounted to 5.77 million tonnes in 2022.

The feldspar raw materials output amounted to 15.03 thousand tonnes in 2022 and it was the 1^st year of a slight output growth (by 3.92 thousand tonnes) after 4 years of a declining tendency. The exploitation from the Pagórki-Wschodnie deposit continued, whereas in the case of the Stary Łom deposit the exploitation was on hold.

The figure given below shows changes in resources and production of feldspar raw materials in Poland in the years 1989-2022.

 

The demand for feldspar raw materials remains high in Poland. The domestic production of feldspar is used mainly in the manufacture of ceramic tiles.

The prognostic resources of the feldspar raw materials are currently being assessed at 61.35 million tonnes, whereas the prospective resources at 37.27 million tonnes*.

The anticipated economic resources of feldspar raw materials decreased by 0.03 million tonnes due to the exploitation and in 2021 amounted to 139.05 million tonnes. There were two deposits exploited: Pagórki Wschodnie and Stary Łom. Still, in spite of a valid exploitation concession, the output from the Karpniki deposit was not resumed.

The anticipated economic resources of the exploited deposits account only for 4.16% of the total anticipated economic resources. The majority of anticipated economic resources are the resources within non-exploited deposits. The economic resources of the exploited deposits increased more than twice as a result of a new deposit development plan elaboration for the Stary Łom deposit and amounted to 5.79 million tonnes in 2021.

The feldspar raw materials output amounted to only 11.11 thousand tonnes in 2021. It was the 3^rd consecutive year with the significant output drop – in comparison with the previous year by more than 60%, and the 4^th consecutive one with the decrease after the 5 consecutive years of its growth. The exploitation level of the raw material from the Stary Łom deposit was equal 7.51 thousand tonnes (in 2020 it was 29.44 thousand tonnes) and the output from the Pagórki Wschodnie deposit restarted.
