  • Nickel Industries A New Force in Global Nickel Nickel

    A New Force in Global Nickel Nickel Industries Limited (‘Nickel Industries’ or ‘the Company’) is an Australian public company emerging as a globally significant, low cost producer of nickel pig iron (‘NPI’), a key ingredient in the production of stainless steelOf course it is inefficient to feed 40% iron into a blast furnace containing high levels of magnesium to boot, but as long as the nickel price stays above a breakeven threshold then the process is profitable (they do get the iron units for nothing and only pay about 10% the value of the contained nickel!!) This is why production of pignickelProcessing Nickel Laterite Ore without Pyrometallurgy

  • Direct extraction of nickel and iron from laterite ores using

    Meanwhile, the production of nickel pig iron in China and India has been supplementing some of the refined nickel in stainless steel production, in the past 15 years (Widmer, 2009) Some of the methods stated above have processing cost advantages over others due to the credits generated from cobalt, copper and other metalsBoth the consumption and production of crude stainless steel in China rank first in the world In 2011, the nickel production in China amounted to 446 kilotons, with the proportion of electrolytic nickel and nickel pig iron (NPI) registering 415% and 565%, respectively NPI is a lowcost feedstock for stainless steel production when used as a substitute for electrolyticCarbothermic Reduction of Nickeliferous Laterite Ores for

  • Metalshub Nickel metal vs Ferronickel

    Ferronickel and Nickel Pig Iron (NPI) are two alternatives to nickel metal NPI typically contains around 4 to 10 wt% nickel Its high amount of carbon (>3 wt%), silicon (>3 wt%) and manganese (>1 wt%) mean that its application in foundries is highly restricted In fact, the main consumers of this product are stainless steel mills in ChinaThis methodology is extremely powerful for checking published data and whether these data are correct in terms of thermodynamics for nickel pig iron processing It is highly recommended to always check the data with suitable flowsheeting software before doing any LCA Lifecycle assessment results for 1 kg of Ni contained in NPIDesign for Resource Efficiency—greenprinting of system
