Indonesia's high-grade nickel ore reserves may be depleted in six years

LONDON/JAKARTA (Reuters): Reserves of high-grade nickel ore in top producer Indonesia may be depleted in around six years, a miners' association has warned, risking shortages of the material used to make stainless steel.

Indonesia's high-grade 1.7% nickel ore is mainly used for the country's nickel pig iron (NPI) production, a feedstock for stainless steel, while lower grade is used to make products for the electric vehicles batteries.
