Abstract:
Low-sulfide platinum horizons in the profile of ultrabasite-basite intrusions take quite an isolated position in relation to the main ore bodies and are located in the areas of the upper endocontacts of these massifs. The main ore-bearing rocks are taxitic chromite-bearing gabbro. Cu and Ni content in the low-sulfide ores does not exceed 0.20-0.40. mas% in sum. The concentration of platinum group elements reaches 20-40 g/t, and in some intersections and pieceы of ore - 60-70 g/t. The main forms of these elements in the ores are their own minerals: sperrylite, sulfides of platinum and palladium, iron-platinum alloys, stannides, stibnidy, arsenides, plumbides, bismuth-tellurides of palladium.
