General information and occurrence
This group of mineral raw materials mainly comprises metals, which are the co-occurring elements in sulfides ores. Such elements occur mainly in zinc-lead ores deposits and copper-silver ores deposits in the Fore-Sudetic Monocline and in the North Sudetic Basin. The elements are being already recovered or may be recovered in the course of the processing of these ores. Accumulations of some of these elements were covered by the prospecting and exploration which resulted usually in the evaluations of their indicated/inferred resources. Sometimes their resources are documented.
Rare earth elements and those named as dispersed elements were also found to occur in beach sands of: the Ławica Słupska deposit (estimated resources equal: zirconium – 2 thousand tonnes of ZrSiO4; titanium – 12 thousand tonnes of TiO2) and the Ławica Odrzana deposit (geological resources approved in 2014 are equal: zirconium – 25.28 thousand tonnes of ZrSiO4, titanium – 156.78 thousand tonnes of FeTiO3 (ilmenite), 20.23 thousand tonnes of TiO2 (rutile, anatase)), in potassium-magnesium salts (boron – 6 thousand tonnes; bromine – 7.2 thousand tonnes) and in brines (32.14 million m3 of brines in the Łapczyca deposit). The data on boron, bromine, zirconium and titanium (except for the Ławica Odrzana area) come from the evaluations made in 1960s and any new calculations have not been made since then.
