For nickel ore, mainstream premiums of nickel ore in the Indonesian market remain around US $35-40/wmt, while nickel ore prices used for hydrometallurgical processincreased by US $2-3/wmt, reflecting tight nickel ore supply in the market. In the nickel sulfate market, last week saw a situation of bargaining between upstream and downstream players. On one hand, downstream demand for ternary precursors and ternary materials recovered after the holiday, and with market concerns about raw material supply, restocking demand for nickel sulfate increased, providing market support. On the other hand, due to Indonesia's nickel ore RKAB quota reductions and news of MHP production cuts, raw material costs remained at elevated levels, providing strong cost support for nickel sulfate prices. Under the combined influence of these factors, nickel sulfate prices remained generally stable last week.
