Development of combined technology for rebellious metamorphized polymetallic ores

Abstract

After study of above mentioned ores material content it was found, that some of them reduce the degree of effective mineral separation by means of flotation. As a result of study of Maleevsky ore energetic parameters made, it was found, that it is possible to use the roentgenoradiometric separation for extraction ores with high platinoid content. The study of thermoelectric properties indicated, that almost all basic ore minerals (except pyrrotine) have both electron and hole conduction, the hole conduction frequently can be found in metamorphizated ores. As distinct of Rydny Altai deposits, where chalcopyrite can have only electron conduction, chalcopyrite of Maleevsky deposit has both electron and hole conduction. It is found, that metal losses in different concentrates are caused by similarity of their electrochemical properties. The study of magnetic properties of zinc concentrates gave the possibility to choose the way of improving their quality by means of magnetic separation. The experiments conducted indicate, that fragmentation class of zinc concentrate does not influence the magnetic fraction distribution, that suppose the possibility of finishing the zinc concentrate in separator magnetic field without pre-classification of size grade. There is a possibility of extracting the magnetic product from zinc concentrate with an output 16.52% operational and content of lead 2.64%; zinc 8.45%; copper 11.73%; iron 33.77%.
