nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties.
the storage and recycle of plant process water. However, there may be a need to treat bleed streams of some process effluents to prevent a buildup of various impurities. Solid wastes from nickel sulfide ores often contain other metals such as copper and precious metals, and con-sideration should be given to further process-ing for their recovery.

A method for heat treating a powder metallurgy nickel-base alloy article comprises placing the article in a furnace at a start temperature in the furnace that is 80° C. to 200° C. below a gamma prime solvus temperature, and increasing the temperature in the furnace to a solution temperature at a ramp rate in the range of 30° C. per hour to 70° C. per hour.
Nickel is primarily used in two areas today: stainless steel and other alloys, and chemical uses including batteries. Stainless steel is the largest part of the nickel market, while batteries are the fastest growing. To meet the global nickel demand, nickel is produced from two main sources: fresh ores and recycled materials. Recycling (whether ...
Nickel metallurgy is a complex process, involving methods of pyrometallurgy, hydrometallurgy, and electrochemical metallurgy. Nearly 20 valuable elements are …
leaching (HPAL), Caron process, and direct nickel process (DNi) are the most common processes to treat lateritic ore [4]. HL process can be processed at ambient temperature, but it is a kinetically slow process, and the yield is low compared to AL and HPAL [5]. AL requires 1 bar pressure and tem-perature in the range of approximately (50–90 °C).

Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into the scene. This is the …
