nickelarsenic

Nickelarsenic is a mineral compound consisting of nickel and arsenic. It is a rare mineral that typically forms in low-temperature hydrothermal veins and as a secondary mineral in nickel-bearing deposits. The chemical formula for nickelarsenic is NiAs, which indicates that it is composed of one nickel atom and one arsenic atom.

Nickelarsenic crystallizes in the hexagonal system and is known for its metallic luster and dark gray to black color. It has a hardness of approximately 5.5 on the Mohs scale, making it relatively soft compared to other minerals. The mineral is often found in association with other nickel minerals such as millerite and nickeline.

The primary use of nickelarsenic is in the production of nickel, which is a valuable metal used in various industrial applications, including stainless steel, coins, and batteries. The extraction of nickel from nickelarsenic involves a series of chemical processes that separate the nickel from the arsenic.

Nickelarsenic is also of interest to mineralogists and geologists due to its rarity and the specific conditions under which it forms. Its study contributes to the understanding of mineral formation processes and the geochemical cycles of elements like nickel and arsenic.
