Chromite mining The Oregon Encyclopedia

Domestic mining for chromite was restricted to a few locations in the United States, including Montana, California, and Oregon, and mining the mineral was only economically feasible during times of political conflict. During wartime, the United States government supported domestic production with price supports and strategic stockpiling programs.

Chromite mining method bbbrerait. Chromite ScienceDirect Although the intention of chromite mining is to remove chromite from the ore for the production of ferrochrome, the process is not efficient, so mining and smelting wastes including dust, wastewater, tailings, waste rock, and slag produced during ferrochrome separation from the ore still can contain different forms of Cr, including CrVI

Chromium processing Britannica

When chromite and lime are melted in an open electric-arc furnace and then contacted with ferrochrome silicon, a low-carbon (0.05 percent) ferrochromium can be obtained. In an alternate process, high-carbon ferrochromium is oxidized and then blended with additional high-carbon ferrochromium.

Chromite Wikipedia

Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and India.

Chromite: The only mineral ore of chromium metal

However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and other metamorphic rocks derived from the alteration of norite and peridotite); and, 3) beach sands (derived from the weathering of chromite

The mining method used for extracting chromite depends greatly on the characteristics of the deposit. These characteristics include whether it is stratiform or podiform, high grade or low grade, subsurface or near surface, or massive or disseminated. Because surface mining typically is less expensive than underground mining, it is preferred, but not always possible. Like mining, beneficiation

Chromite Wikipedia

Chromite mining, chromium, and ferrochome production can toxically effect the environment. Chromite mining is necessary when it comes to the production of economic commodities. As a result of leaching of soils and the explicit discharge from industrial activities, weathering of rocks that contain chromium will enter the water column. The route of chromium uptake in plants is still ambiguous

Chromite ore SlideShare

Rock containing chromite ore Mining Method Extraction of the Chromite Ore Both surface and underground mining methods will be used to mine the chromite. Mining produces both ore and waste rock. Waste rock consists of all other non-chromite bearing rock excavated during mining. Surface Mining Chromite ore is mined by surface methods.
