The reduction process is very fast in the submerged lance furnace. Charging times are short. The iron silicate sand extracted in that step of the process has very low residual copper contents. Copper, nickel, tin, lead and the precious metals contained in the raw materials are enriched in an alloy with a copper content of about 80 %.

Nickel pig iron - Wikipedia

Nickel pig iron (NPI) is a low grade ferronickel invented in China as a cheaper alternative to pure nickel for the production of stainless steel [citation needed].The production process of nickel pig iron utilizes laterite nickel ores instead of pure nickel sold on the world market. The alternative was developed as a response to the high price of pure nickel.
