Korvalehden

Korvalehden is a rare mineral resource described in the fictional world of Eldara. It occurs in hydrothermal veins within the Korval Range and is notable for its combination of metallic luster, hardness, and electronic properties. The mineral is defined chemically as a nano-crystalline complex of sulfide and silicate phases, with a typical density of 6.0–6.5 g/cm3 and a refractive index of about 2.1. At cryogenic temperatures it displays a degree of superconductivity, making it attractive for high-performance conductors and specialty optics. Its occurrence is restricted to high-grade metamorphic terrains, often with magnetite, chalcopyrite, and pyrite.

Discovery and naming: Korvalehden was first described in field reports from 1978 by geologist Aira Vork during surveys of the Korval Range in Eldara. The name derives from the local term korval meaning "shadow" and the suffix -heden meaning "stone".

Occurrences: principally in select districts of the Korval Range; irregular veins; small but consistent ore bodies; depth often 1.5–3.5 km.

Extraction and processing: mined via underground methods; ore concentrated by flotation; refined through smelting and electrorefining; impurity control essential to preserve electronic properties.

Uses: primary uses include superconducting cables for cryogenic applications, high-precision optics, and catalytic materials for chemical processing. Some industrial markets view it as a strategic mineral.

Economy and regulation: production limited by geology and extraction costs; a handful of mining firms control supply; export licenses and environmental regulations affect trade; price sensitive to global demand for advanced technologies.

Environmental and safety: mining requires dust control, water treatment, and tailings management; occupational health measures are standard.
