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 high market value, are already recovered or may become recoverable in the course of processing of these ores. Accumulations of some of these elements were covered by prospecting and exploration which resulted often 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: zirconium – 2 thousand tonnes of ZrSiO4; titanium – 12 thousand tonnes TiO2) and Ławica-Odrzana deposit (geological resources approved in 2014: zirconium – 25.28 thousand tonnes of ZrSiO4, titanium – 156.78 thousand tonnes of FeTiO3, 20.23 thousand tonnes of TiO2), potassium-magnesium salts (boron – 6 thousand tonnes; bromine – 7.2 thousand tonnes) and saline waters and brines (32.16 million m3 of brines in Łapczyca deposit). The data on boron, bromine, zirconium and titanium (except for 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 estimations of resources of major co-occurring elements (thousand tonnes).
In 2015 there was a new copper ores deposit – Radwanice-Gaworzyce – documented and the resources of co-occurring elements were assessed. The calculations were made for: lead, cobalt, molibdenium, nickel and vanadium (table 3).
