higikanalite

Higikanalite is a rare mineral species that belongs to the group of arsenates. It was first discovered in 1983 at the Higashi-Kagawa mine in Japan, from which it derives its name. The mineral is known for its distinctive bright yellow color and is typically found in small, well-formed crystals.

The chemical formula of higikanalite is Cu9(AsO4)2(SO4)(OH)10·8H2O, indicating that it is composed of copper, arsenic, sulfur, oxygen, and hydrogen. It is a secondary mineral, meaning it forms from the alteration of primary minerals. Higikanalite is often found in association with other secondary minerals such as brochantite, langite, and olivenite.

Higikanalite crystallizes in the monoclinic crystal system, and its crystals are usually tabular or prismatic in shape. The mineral has a Mohs hardness of about 2.5 to 3, making it relatively soft. It has a specific gravity of approximately 3.2 to 3.3, which is relatively low for an arsenate mineral.

Due to its rarity and aesthetic appeal, higikanalite is sought after by mineral collectors. However, it is important to note that the mineral contains arsenic, which is toxic, and should be handled with care. Higikanalite is not known to have any significant industrial uses.

In summary, higikanalite is a rare, bright yellow arsenate mineral that forms in small, well-shaped crystals. It is primarily of interest to mineral collectors and is not known to have any significant practical applications.
