The exploration of podiform chromites in the Indus Yarlong Zangbo suture zone of southern Tibet has proved difficult because most known deposits pinch out and then reappear in the same direction Several ground based geophysical approaches such as gravity magnetic and controlled source audio frequency magnetotelluric CSAMT methods have been applied to explore for these chromite deposits
UNOCAL reported on April 18 1986 in a final report it issued to Ministry of Mines of New Caledonia a historic chromite resource which was classified as an indicated resource contained within the exploration licence areas it held UNOCAL reported that the deposit contained million tonnes of chromium oxide It was reported that the mineralization occurs within a area averages
Chromites from the chromite two groups of soil chromites CS1 chromitic sand and vein also possessed an and CS2 could be distinguished The CS1 group homogenous composition different from dunite originated exclusively from subsurface horizons compositions richer in Cr with respect to Al NIQ II 1 NIQ III 1 and 3 Their composition Fig 3 The composition of soil chromites was
Chromite foundry sands are generally mixed with binding resins and hardeners to produce molds They substitute silica sands to cast metals with high density and high melting point and are much cheaper when compared to zircon sand [] They have to meet strict quality parameters in order to ensure a good final product [] The most important ones are Cr 2 O 3 content higher than 44% Fineness

Pody form chromite deposits are available in KPK province with tens of thousands of tones in proven category The chromites are found in lenses associated within ultra mafic rocks along major suture zones After detail exploration including drilling tunneling & sampling a total of about million tones deposits have been estimated in proven category with grade of Cr2O3 above 40%
Exploration in Ontario Chromite was first surveyed in Ontario in the 1930 s by a small operation Chromite Mining and Smelting Corporation Limited The company mapped out a 25 000 ton deposit in 1934 from the Puddy Chrome Lakes area The extent of this operation was extraction of bulk samples that were tested for suitability as a concentrate The company went out of business in 1937
Chromite grains are considerably enriched in the sand fraction of most rivers that have part or all of their catchment in peridotite Chromites grains are residually concentrated in the weathering profile The heavy minerals are then easily separated from the soft laterite by physical erosion and form conspicuous and ubiquitous trails and lenses in the hydrosystem onshore along the shore and
Exploration has highlighted the prospectivity of the Murray and Eucla Basins Tertiary deposits Murray Basin The Early Pliocene Loxton Sand and overlying Parilla Sand formations have been the target of mineral sand exploration in the Murray Basin During the 1980s one of the world s largest accumulations of heavy minerals was delineated by drilling in the basin near Horsham in Western
The chromite sand from the Oregon deposit is significantly different than that supplied by South African producers The grain structure of the South African chromite has a rhombohedral grain shape which is formed when the mineral is crushed during the mining operation This crushing is necessary to produce the particle sizes for the various markets they supply such as the steel industry
