Nickel - Wikipedia

Nickel is obtained from nickel carbonyl by one of two processes. It may be passed through a large chamber at high temperatures in which tens of thousands of nickel spheres, called pellets, are constantly stirred. The carbonyl decomposes and deposits pure nickel onto the nickel spheres. In the alternate process, nickel carbonyl is decomposed in a smaller chamber at 230 °C to create a fine nickel

Environmental Impacts of Nickel Mining and

After the closure of mines in the Philippines, its nickel production dropped from 347,000 metric tons in 2016 to an estimated 230,000 metric tons in 2017; however, during that same period Indonesia’s production doubled from 199,000 to 400,000 metric tons (4). It is difficult to address problems such as this on a global scale and exact any tangible changes. However, change can be made on a personal level.

Nickel is re-obtained from the nickel carbonyl by one of two processes. It may be passed through a large chamber at high temperatures in which tens of thousands of nickel spheres, called pellets, are constantly stirred. It then decomposes, depositing pure nickel onto the nickel spheres. Alternatively, the nickel carbonyl may be decomposed in a smaller chamber at 230 °C to create a fine nickel powder. The

Nickel / cobalt mining extraction procedures

One of the most used processes to treat nickel and cobalt “speiss” is that used by the company, Sherritt Gordon Mines Ltd, from Fort Saskatchewan, Alberta, Canada. Sherritt Gordon Process The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a “speiss”, rich in cobalt and nickel.

BHP Ravensthorpe Nickel Operation, Australia

The process downstream of the leaching circuit uses a Cawse flowsheet with partial neutralisation, followed by separation of the barren tailings from the nickel-bearing solution, further impurity removal and precipitation of the MHP. This is then transported to the Yabulu refinery via the port of Esperance, about 120km to the east, where it is processed into nickel.

Nickel mining in Indonesia - Wikipedia

The most important Indonesian nickel ores are lateritic, primarily located in Sulawesi and Halmahera with mining operations centered at ultramafic rock outcrops. While the lateritic nickel ores are more difficult to smelt compared to nickel sulfide ores, it is more extractable due to its location on the surface.

This process was patented by L. Mond and has been in industrial use since before the beginning of the 20th century. In the process, nickel is reacted with carbon monoxide at around 40–80 °C to form nickel carbonyl in the presence of a sulfur catalyst. Iron gives iron pentacarbonyl too, but this reaction is slow.
