Rare earth element (REE) mineralization in the weathered granites of Primorye is localized in the basement rocks and rocks along the periphery of the coal-bearing basins, which have been recently tectonically faulted and folded and have undergone argillisite metasomatism. It was shown that the clay material from the zones of intense argillization can be a source of scarce REE and yttrium. The ion-sorption and carbonate forms of REE+Y in them in combination with the clay composition of most of the ores make it possible to use cheap and low-toxic salt and hydrochloric acid solutions during heap leaching.
