2020-4-24 NPI smelting costs to rise as Indonesia puts floor price for nickel ore. Apr 23,2020 23:02 CST. industry news. Source: SMM. Nickel pig iron (NPI) smelters invested by Chinese companies in Indonesia will face an increase in smelting costs as Indonesia has planned to implement a floor price on nickel ore, which is aimed at preventing local smelting ...

Nickel ore must melt until it becomes a product known as liquid matte, which is usually around 45 percent nickel. Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which contain nickel; and sulfidic ore

Smelter investment costs, per annual tonne of nickel in ferronickel production, are influenced by smelter feed grade rather than by ore grade. The higher the grade of nickel in the smelter feed, the smaller the smelter (and smelter investment) for a given annual tonne of nickel in ferronickel production.

We claim 1. A process for producing ferronickel from nickel oxide ores which comprises: 2. The process of claim 1 wherein the nickel ore is chosen from the group consisting of laterites and serpentines and wherein said ore is calcined at a temperature sufficiently high to remove most of the chemically combined water contained in the ore prior to smelting.

The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled dust. Roasting is carried out in rotary kilns (~3 m in diameter, ~75 m in length, with a hot zone length of 9 to 12 m in the case of lean ore ...
