Chromite and Other Mineral Deposits in Serpentine Rocks Of ...

Small deposits of titaniferous iron ore in serpentine were mined for iron before 1900, but the titanium content troubled furnace operators. Ore bodies are similar in occurrence to chromite deposits; they are massive or disseminated and are found near the edges of serpentine intrusive rocks. The small size of

Serpentine is a group of common rock-forming hydrous magnesium iron phyllosilicate ((Mg, Fe) 3Si2O5 (OH) 4) minerals; it may contain minor amounts of other elements including chromium, manganese, cobalt and nickel.

Industrial Minerals

Market Brief. Chromite is the commercial name for iron chromium oxide (FeCr 2 O 4), a mineral containing chromium (a transition metal with multiple oxidation states) and iron oxide.In its purest form, chromite comprises chromium (Cr 2 O 3) at 68% and iron oxide (FeO) at 32%.. Chromite occurs exclusively in ultramafic rocks such as dunite, peridotite, pyroxenite and serpentinite.

The numerous masses of serpentinite and associated mariposite are also important in localization of the ore bodies (Clark and Fuller, 1968). Approximately 80% of the district's production has come from portions of the veins where serpentinite either formed one wall or was less than 100 feet from the ore (Ferguson and Gannett, 1932).

The Nephrite Jade Road: Evolution of the Green Nephrite ...

Along with the skyrocketing price of white nephrite, there is also a developing market for green nephrite in China. However, limited local supply has forced the Chinese to seek outside resources, opening the door to imports of green nephrite mined in British Columbia, Canada, and Siberia, Russia. This has created the well-developed and well-maintained nephrite jade road that connects the three ...

Serpentinite - Wikipedia

Serpentinite is a rock composed of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. Minerals in this group, which are rich in magnesium and water, light to dark green, greasy looking and slippery feeling, are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from ...

Nickel Deposits of - USGS

nickel ore deposits are closely associated with mafic and ultramafic in­ trusive rocks, and the nickel in the ore bodies was probably derived either from the intrusives themselves or from similar rocks at depth. Thus the original source of most of the nickel ore bodies found in North America and elsewhere in the world was probably the mantle.

Cobalt Statistics and Information - USGS

Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military applications, many of which are strategic and critical. On a global basis, the leading use of cobalt is in rechargeable battery electrodes. Superalloys, which are used to make parts for gas turbine engines, are another major use for cobalt. Cobalt is also used to make airbags in

Comparison between bentonite and serpentinite in the ...

The results obtained show that the full substitution of bentonite for serpentinite is unfeasible. However a potential does exist for using serpentinite and bentonite together in the iron ore palletizing process in the proportion of 1:1. Keywords: iron ore pelletizing, serpentinite, bentonite.
