Jindal Stainless India s largest stainless steel manufacturer has commissioned its nickel pig iron smelter facility in Halmahera Islands Indonesia eight months ahead of schedule according to a stock exchange filing The company operates 16 stainless steel manufacturing and processing facilities across India and abroad including in
5 However given the limited Ni/Co medium and high grade > % Ni reserves worldwide several issues are of paramount importance including the complex and resource intensive extraction and refining processes that are necessary for their processing geopolitical considerations ethical/social concerns in several mining regions as well as the security and
Indonesia s high grade % nickel ore is used mainly to produce nickel pig iron a feedstock for stainless steel with EV batteries using lower grade nickel
The RKEF process was first applied commercially to treat New Caledonian ore in the late 19th century [3] In general the literature establishes three stages in the RKEF process [1] [4] [10] [11] I drying or preheating in a rotary dryer II calcination and partial reduction in a rotary kiln and III smelting in an electric arc RKEF process is quite mature and

How Indonesia Beat the Philippines to Become the World s Undisputed Nickel Pig Iron NPI Producer and Likely to Replicate this as a Battery Feedstock Supplier and 3 stainless steel plants operating in Indonesia Yearly these process plants convert over 50 million tonnes laterite nickel ore into approx 800 000 tonnes nickel metal in
Indonesia s first nickel pig iron smelter has begun initial production of about 1 000 tonnes of ingots a day kicking off a wave of new metal processing plants planned in the next few years
These types of pig irons are useful to dilute all elements in a ductile iron charge except C which can be harmful to the ductile iron process Nickel pig iron Nickel Ni pig iron is a ferro nickel pig iron containing 3 % to 13 % of Ni
The technological process of producing nickel pig iron NPI by smelting laterite ore in blast furnace is basically the same as that of modern BF smelting for producing pig iron from iron ores as shown in Fig Initially the laterite ore is crushed mixed with flux and fuel and then sintered in a sintering machine
Compared to the typical sulphide flowsheet nickel laterite processing is more varied Around 80% is processed pyrometallurgically and much of that is offshore after selling DSO 44% is produced as Nickel Pig Iron 36% as Ferronickel with the balance mostly Briquette or Hydroxide In summary
In 2011 the nickel production in China amounted to 446 kilotons with the proportion of electrolytic nickel and nickel pig iron NPI registering % and % respectively
The process is well investigated and widely used for production of DRI pig iron and nickel pig iron Sarangi and Sarangi 2011 The initial approach in the 1970s was to minimize the reduction of Iron and to use appropriate conditions for preferential nickel reduction
In this study laterite steel was prepared from converting nickel pig iron followed by de slagging and decarburization process Detailed steel making procedure was described elsewhere [12] The
The producer of nickel pig iron is expanding into high purity nickel for the EV industry and is building a $ billion plant in Indonesia s Morowali that will supply products such as nickel
The technological process of producing nickel pig iron NPI by smelting laterite ore in blast furnace is basically the same as that of modern BF smelting for producing pig iron from iron ores as shown in Fig Initially the laterite ore is crushed mixed with flux and fuel and then sintered in a sintering machine
Processing Operations • Nickel production was 35 284 tonnes during the quarter comprising o 21 882 tonnes of nickel in nickel pig iron NPI and low grade nickel matte LGNM at a cash cost of $10 288/t and an all in sustaining cost AISC of $10 370/t o 13 402 tonnes of nickel in high grade nickel matte HGNM at a
The company was founded in 1954 as Scambi Economic SA Goa Since then it has grown to be one of the country s top low cost producers of iron ore During 1991 1995 it diversified into pig iron and metallurgical coke manufacturing
Tsingshan is the world s largest stainless steel producer and a leading producer of both class 1 and class 2 nickel Tsingshan who pioneered the Rotary Kiln Electric Furnace RKEF process to produce low cost nickel pig iron NPI is now the dominant player in the Indonesian NPI industry and a global leader in NPI processing technology including having implemented the Argon
In addition to ferronickel and nickel matte some other product types produced by pyrometallurgical routes are nickel pig iron NPI and sponge ferronickel or so called nickel luppen [1] [2] In
The Nippon Yakin plant in Oheyama used this process for the treatment of laterites to obtain ferro nickel lumps during the Second World War and the process is called the Oheyama process Dong X Technology and development of nickel pig iron blast furnace Presented at the 2017 SEAISI Conference & Exhibition Singapore 22 25 May 2017;
nickel processing industrial park including new nickel plants and RKEF processing plants The SCM mine will supply nickel saprolite ore to RKEF plants producing nickel pig iron at the Indonesia Morowali Industrial Park IMIP including SI and SI smelters The SCM mine will also supply nickel limonite ore to nickel high pressure acid
