They include materials like iron ores, copper chloride residue, salt and salt sludge, ammonium paratungstate, chromite ore fines, nickel laterites, petroleum coke, rare earth oxides, zinc oxide flue dust, red mud, and ferrochromium

When waste ferrochromium
aggregates were added in mixture, it increased the splitting tensile strength.
Among the topics are removing inclusions by gas bubbles in a steel continuous casting tundish, estimating slag in ferrochromium
, the influence of red mud content on the mechanical properties of natural fiber-reinforced polymer composites, creep cavitation and fracture in single-crystal superalloy, the microwave dielectric characterization of silicon dioxide, the thermal conductivity of inorganic-filler/resin composites, and the organophilization of a Brazilian kaolin clay.
The concentrate is used to make ferrochromium
, which is in turn used to make stainless steel and some other alloys.

China's growing appetite for foundry sand and ferrochromium
has helped drive prices up to five times what they were when Oregon Resources first showed up here, Wilson said.
(4,5) There is much research on chrome-based colourants.6-10 In order to obtain appropriate coloured powder as high temperature grey pigment, Bondioli, Barbieri and Manfredini (11) were mixed with (Fe, Zn)[Cr.sub.2][O.sub.4], ferrochromium
fly ash having spinel that is rich in terms of iron by adding two different chrome precursors, [Cr.sub.2][O.sub.3] and Cr[(OH).sub.3].
