chromite sand slurry mining

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 Wikipedia

Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can

Slurry Pumping in the Oil Sands Industry Canadian Mining

Aug 06, 2020· The liquid pumped is a mixture of water, bitumen, sand, and large rocks. Screens are in place to keep these rocks to a manageable size for the process, but the top size can still often reach up to 130 mm in diameter (or larger). The abrasive nature of the slurry is what separates a slurry pump apart from other pumps used in the industry.

Improving the Quality of Ferruginous Chromite Concentrates

The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.
