Processing of Nickel Laterite Ores on the Rise

Nickel is most widely used in the production of stainless steel. Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores

What is Sulfide Mining? Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...

Russian nickel deposits are classified as nickel sulfide, which are the primary source of high-grade nickel ore. According to Ahead of the Herd, 58 percent of global nickel production comes from nickel sulfide. The largest sulfide deposit in the country is found in Norilsk, which also happens to be the largest across the globe.

PENTLANDITE (Iron Nickel Sulfide)

Pentlandite is an important ore of nickel. However, it does not produce good crystals and is generally only found in massive form. It is commonly associated with other sulfides such as pyrite, chalcopyrite and pyrrhotite in basic igneous rock intrusions. These sulfide ore bodies are probably produced through magmatic segregation.

Sulfide Ore Article about Sulfide Ore by The Free Dictionary

Sulfide ores may be simple or complex. Complex sulfide ores containing sulfides of copper, zinc, and lead are especially common, as are complex copper, nickel, cobalt, antimony, and mercury ores. Many sulfide ores contain Pt, Au, Ag, Cd, In, Se, and Te as admixtures.

Smelting of Nickel-Copper and Nickel Sulfide

Sulfide ores are mostly smelted by matte-making. Different pyrometallurgical processes are used to produce low-nickel matte from various nickel sulfide ores. Then low-nickel matte is converted into high matte, i.e. sulfide and copper sulfide alloys. High matte is then refined by different methods in a refinery to produce different nickel products.

Nickel: smelting, producing-Metalpedia

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then ...
