19-05-2017 Rhodochrosite is a manganese carbonate mineral with the chemical composition MnCO3. The mine is located in the Andalgalá Department, Capillitas Province, in northwestern Argentina. Mined since Incan times, the polymetallic sulphide veins at the Capillitas Mine were worked in the 17th century for silver, and later for lead and zinc.

One of the most famous forms of Rhodochrosite are the blood red, clear, scalenohedral crystals that come from the Kalahari Manganese fields of South Africa, in Hotazel and the N'Chwaning Mines of Kuruman. Dark red Rhodochrosite crystals were found in the Moanda Mine, Leboumbi-Leyou, Gabon.

11-08-2018 Rhodochrosite is a manganese carbonate. Its value now resides almost entirely in the quality of its hot pink and deep red specimens, which are sought after by collectors and command extremely high prices. Specimens from 13th century Inca mines in Argentina are the origin of one of the more alluring names for the mineral, Inca Rose.

Rhodochrosite (whose name means rose-colored) is a very attractive mineral with an absolutely one-of-a-kind, beautiful color. Although it can be an ore of manganese, it is its ornamental and display specimen qualities that make it a very popular mineral. The color of a single crystal can just astound the observer with its vivid pink-rose color that seems to be transmitted out of the crystal as ...

Rhodochrosite is a manganese carbonate (MnCO 3) mineral.The color is brilliant and transparent yellow, pink, and rose/cherry-red (Fig. 1.45) with 47.79% Mn in its purest form.The crystal system of rhodochrosite is trigonal. The fracture is uneven to conchoidal with brittle tenacity, vitreous to pearly luster, and white streak.

Rhodochrosite, a carbonate ore, is one of the most important Manganese ores (8). Mining for Manganese ore is generally done in open pits. Pure Manganese is produced by hydrometallurgical and electrolytic processes (8). Manganese is rarely used by itself due to its natural hardness. It is used in various metallic alloys, one such alloy is steel (3).

It is also interesting to note rhodochrosite’s role in mining. Manganese carbonate is detrimental to the process of amalgamation. For that reason, miners tended to discard rhodochrosite when they encountered it in the mine dump before it was realized that some pieces might be gem quality and that they could fetch a high market value.

Manganese is widely distributed in nature, and almost all kinds of ores and silicate rocks contain manganese. In modern industry, manganese and its compounds are widely used in various economic fields, of which the iron and steel industry is one of the most important fields.

Neutral mine waters can also contain manganese, largely due to the extremely slow rate of Mn oxidation. Such waters can also contain substantial carbonate alkalinity. Manganese carbonate is fairly insoluble at moderate pH; a 2 mg/L can be established through manganese carbonate control at pH 8.5. Hem and Lind (1983) note that MnCO3 (rhodochrosite)
