CS 122 Chromite Separation. Aug 21, 2013· As can be seen from the above XRF results, the seperated chromite sand contains less than 05% silica contamination and therefore is perfect for re-use at the mixer As a general side effect from the casting process, the chromite sand tends to see most of the heat from the molten metal and so is also naturally thermally reclaimed...
low silica content • pH and Acid Demand Value - important tests in predicting issues with curing and strength development in chemical binder systems • LOI- Loss on Ignition - can be used to look for accessory minerals and impurities associated with the chromite sand. • Turbidity- an indicator of the cleanliness of the chromite sand
Chromite Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.
1.00 pound of Chromite displaces 152cc vs. 295cc for Play Sand. So, that means Chromite is 94% heavier than an equal volume of Play Sand. Riverbed Sand -- Weighs Less but Costs More than Chromite Riverbed sand, is about 30% less dense than Zircon or Chromite, but is about 150% more dense than silica sand.
core sand being reclaimed, will result in a corresponding change in the amount of ... silicon dioxide (SiO2) limits in chromite sand to avoid sintering reactions and reactions ..... environmentally undesirable contaminants in the discarded sand.
Academia.edu is a platform for academics to share research papers.
The amalgamation of chromite sand and silica sand, which arises inevitably at the shake-out station, may lead to quality problems of the casting in case of reuse of the reclaimed sand. With G U T plants chromite sand can be separated sorted from silica sand and can easily be re-used in the sand circuit for cores and moulds.

The high chromium content of typical 48% Cr2O3 and low silica of typical 0,9% SiO2, coarse sizing and high Cr:Fe ratio of close to 2:1 makes our refractory grade being appreciated world-wide. Plomp Mineral Services' focus is on supplying refractory grades chromite of South African origin with .
Sand used in the foundry industry is washed, graded, and dried. Since silica sand is common and inexpensive, it is the most commonly used mineral. However, when physical or chemical conditions dictate, other sands are chosen, such as zircon, olivine, or chromite. Chromite foundry sand is used in the ferrous and copper casting industries.
` The refractoriness of the silica sand is highest. Fineness ² ` Finer sand molds resists metal penetration and produces smooth casting surface. ` Fineness and permeability are in conflict with each other and hence they must be balanced for optimum results. Bench Life ² ` It is ability of the molding sand to retain its properties during storage.
Due to ceramic sand's unique physical and chemical properties, it can be used in a wide variety of foundry processes. Ceramic sand can serve as a replacement for silica sand, and substitute for both chromite and zircon sands in many applications.
The separated chromite sand contains less than 0.5% silica contamination and therefore is perfect for re-use at the mixer. As a general side effect from the casting process, the chromite sand tends to see most of the heat from the molten metal and so is also naturally thermally reclaimed.
Chromite sand is para-magnetic, that is it is only slightly magnetic and cannot be effectively removed by standard rare earth magnets without contamination of metal and silica. Even with a series of drum magnet separators, what tends to happen is that there is always a carry-over of silica sand making the quality of the reclaimed chromite poor ...
