PECULIARITIES OF DISTRIBUTION AND A MODEL FOR THE MECHANISM OF FRACTIONATION OF PLATINUM GROUP METALS IN SULFIDE NICKEL ORES OF THE ELAN-TYPE DEPOSITS. ARTICLE 1. SULFIDE NICKEL ORES IN THE ELAN-TYPE DEPOSITS AND PECULIARITIES OF DISTRIBUTION OF PLATINUM GROUP METALS
The basic patterns of distribution of platinum group metals in ore deposits such as Elan are identified. The correlation between the noble metals and the main ore-forming components (Ni, Cu, Co), as well as the leading role of arsenide sulfoarsenide paragenesis in their distribution are established
