Rare-Earth Element Mineralization in Argillized Granites of Southern Primorye: New Data

  • Published:
Russian Journal of Pacific Geology Aims and scope Submit manuscript


Rare-earth element (REE) mineralization in weathered granites of Primorye is localized in the basement rocks and rocks surrounding coal-bearing basins, which have been recently deformed and undergone argillic metasomatism. It was shown that the clay material from the zones of intense argillization can be a source of deficient REE and yttrium. The ion-sorbed and carbonate REE+Y species in them in combination with the clay composition of most of the ores make it possible to use inexpensive and low-toxicity salt and hydrochloric acid solutions during heap leaching.
