The Jinchuan deposit, China,ed as the third largest economic Ni-Cu deposit in the world after Noril’sk and Sudbury (see Table 1.1, Chap. 1). Ores of the deposit are relatively rich in Cu with an average ratio Ni/Cu = 1.76 (see Table 1.1) and have moderately high PGE concentrations with a total PGE and Au content of around 1 pp
