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 (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.

to softening nickel prices. Market reaction to the construction timelines and funding requirements to build the high pressure acid leach facility has since become skeptical. Increased availability of nickel pig iron supply was another contributing factor in weakening nickel prices.

sulphuric acid. The nickel laterite ore samples were received from Gag Island in Indonesia. After solid-liquid separation, iron precipitation was performed by pH adjustment and solution aeration for 24 hour. After separations of the iron precipitate, the filtrates are collected for further nickel hydroxide precipitation tests. The precipitation

The smelting of Nickel Pig Iron (5–10% Ni mostly in China) from laterite ore grades that are not suitable for producing standard grades of FeNi (20–45% Ni). The low liquidus temperature of NPI with higher carbon and silicon contents allows lower furnace operating temperatures and hence lower melting point slags to be used with SiO 2 /MgO ...
Nickel production is unlikely to receive a boost from smelters who planned to shift from nickel sulphate production to refined nickel, as they may give up the plan in August. In July, output of nickel pig iron (NPI) in China rose 2.57% from June to 50,700 mt in Ni content.

Nickel Pig Iron, or NPI in short, is a ferronickel that is used as a cheaper alternative in the production of stainless steel. NPI is made of laterite nickel ores, which are then heated in a blast furnace or electric furnace together with coking coal, sand and gravel.
Last week, Chinese nickel giant Tsingshan agreed to supply 100,000 tonnes of nickel 'matte' converted from lower quality nickel pig iron (NPI) to battery midstream majors CNGR and Huayou Cobalt. This sent shockwaves through the nickel market. The LME price promptly fell ~14 per cent and has yet to recover. Nickel price over the past year.
Average nickel prices for the quarter were similar to the second quarter, however, markets saw a pullback in pricing during the month of September largely due to stronger than anticipated nickel pig iron production data from China and continued gains in LME inventories . The average reference price

According to SMM survey, the domestic stainless steel output in August totalled about 2.82 million mt, down 103,000 mt or 3.53% month on month but up 2.19% year on year. China's output of stainless steel totalled 22.53 million mt in January-August, an increase of 22.65% year on year. Aluminium prices fluctuated rangebound today.
In 2011, the nickel output of China amounted to 446 kt, with the proportion of electrolytic nickel and nickel pig iron (NPI) registering 41.5% and 56.5%, respectively (Fig. 5).The nickel feed source accounts for about 70% of the total cost of Ni austenitic stainless steel production.33 As a substitute for scrap steel and electrolytic nickel, NPI can reduce the cost of stainless steel production.

Tsingshan, the world's largest nickel producer, announced last week that it will supply nickel matte based on converted nickel pig iron (NPI) from its operations at Indonesia Morowali Industrial Park (IMIP) to Chinese companies Huayou and CNGR Advanced Materials, which will be further processed to produce battery-grade nickel sulphate. Tsingshan will supply 60kt of nickel …
Nickel is essential to steel and car production, and is a very popular component of alloys. Stainless steel production — almost exclusively in China — is the single largest demand segment for primary nickel, accounting for nearly 70% of overall demand. Nickel pig iron is the most prevalent source of new nickel supply.
separate iron and produce a high grade nickel matte2. The nickel matte can then be further refined in a similar way to a mixed nickel-cobalt sulphide precipitate to produce Class I nickel or battery grade chemicals. The flowsheet below summarizes the conversion process:
Nickel is a strategic element that has many application areas in the industry. 2/3 of nickel is used in stainless steel production. In recent years, low grade nickel containing iron (Nickel pig ...
However the additional reduction of iron oxide lowers the Ni grade (albeit normally increasing the Ni recovery to some extent) and can result FeNi with Ni contents well below the normal specification of 20% (i.e. typically between 5 and 15%). These low Ni grades are typical of nickel pig iron (NPI) that has grown significantly as a
immiscibility of nickel sulphide rich matte and iron oxide based slag. Once the target matte level is reached the matte is tapped and sent to converters. A segment of Vale's Copper Cliff Smelter flowsheet is given in Figure 1. The matte generated during flash smelting is a homogeneous mixture of nickel, copper, cobalt, iron and sulphur.
