Nickel is an important strategic metal produced at over 2 million tonnes annually [1].Approximately 60% of all Ni is consumed in the production of stainless steel [2, 3].Currently, Ni is primarily extracted from two types of ores: laterites and sulfides [[4], [5], [6], [7]].Although sulfide ores account for a smaller fraction of global Ni reserves, approximately 60% of global Ni …

Nickel ore refers to the naturally occurring rocks or minerals that contain significant amounts of nickel. Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white metal with a relatively high melting point and excellent corrosion resistance. Nickel is commonly found in the Earth's crust, but it is typically extracted from its ore minerals through …

The pressure oxidation of low-grade nickel sulfide concentrate with high iron sulfides content generates significant amounts of sulfuric acid that must be neutralized. This acid can be utilized to leach metal values from ores such as nickel laterites. The present study demonstrates the use of a low-grade nickel concentrate generated from Poseidon Nickel Mt …

Nickel sulfide ores associated with komatiites in Archean greenstone belts are the most important examples of mag- matic mineralization in volcanic rocks. They contain about 25 percent of the world total identified nickel resource in deposits with ≥0.8 percent Ni, as well as significant amounts of copper and platinum-group elements (PGE).

Nickel is an important strategic metal resource, which plays an important role in national defense, aerospace, new energy and other fields. In recent years, low-grade nickel sulfide ore (LGNSO) has become the main raw materials for nickel extraction due to the depletion of high-grade nickel sulfide ore resources [1].However, the effect of the traditional smelting …

Low-grade ores, like nickel sulfide, are abundant on Earth. Nickel sulfide deposits contain high levels of magnesium silicate gangue minerals (MgO) and can be difficult to process with conventional flotation and smelting technologies. MgO is hydrophilic, which interferes with the flotation of sulfide minerals and reduces flotation recovery.
