Ways of implementation and suitability of world's recent developments in mineral processing of nonferrous metallic ores for Polish LGOM deposits have been analyzed in the paper. A great number of problems, which occur during processing of the Polish ore are similar to those appearing in other worldwide nonferrous ores. It includes depletion of available deposits and decreasing quality of the ores making them difficult-to-treat materials. As a result a continuous improvement of mineral processing plant equipment to the changing parameters of ore becomes crucial. There also is a need for introduction of new technological flow sheets that include a combination of flotation and chemical methods to effectively recover valuable minerals. A review of concepts of currently used types and amounts of reagents, and if necessary, their adjustment becomes a key factor of the efficiency of the process. An application of economically feasible new methods of tailing utilization and implementation of a simple supplementary processing step for flotation of tailing just before sending it to the tailing pond probably are also worth to be considered.
