Metals and elements coexisting in ores and in other raw materials
This group of mineral raw materials mainly comprises metals, which are co-occurring elements mainly in sulfides ore deposits. This is the case of Polish copper and zinc-lead deposits with fairly long records of various co-occurring elements. The elements, often of a high market value, are already recovered or may become recoverable 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 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: Ławica Słupska (estimated resources equal: zirconium – 2 thousand tonnes of ZrSiO4; titanium – 12 thousand tonnes of TiO2) and Ławica-Odrzana deposit (geological resources approved in 2014 equal: zirconium – 25.28 thousand tonnes of ZrSiO4, titanium – 156.78 thousand tonnes of FeTiO3, 20.23 thousand tonnes of TiO2), in potassium-magnesium salts (boron – 6 thousand tonnes; bromine – 7.2 thousand tonnes) and in saline waters and brines (32.16 million m3 of brines in 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 has not been made since then.
Table 1 shows a summary of resources estimations of major co-occurring elements (thousand tonnes).
The state of resources exploration and the state of their development together with the output magnitude of elements co-occurring in lead and zinc deposits and copper deposits are presented in Table 2 and Table 3, respectively. The part of indicated/inferred resources of these elements co-occurring in copper ores deposits has been determined within anticipated sub-economic resources of the ore.
