Abstract
Sequential leaching of gold-bearing ore of the residuum is described. The interconnection between rare earth elements and their mineral matrix is defined. The mobility of REE in the initial ore and during hypergenesis is assessed. Two kinds of REE are revealed: fine monazite cerium–neodymium crusts in iron-bearing minerals and dense monazite pockets in titanium-bearing minerals. The five-stage sequential leaching procedure allows more detailed distribution of elements in the rebellious matrix while the threestage procedure focuses on mobile forms.
