What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr2O4). It is dark gray to black in color with a metallic to submetallic luster and high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks …

The sample size was made of two types of local foundry sands: silica sand and chromite sand. These samples were donated by two local foundry sand suppliers. An amount of 1100g of each sample was collected for testing. 2.3 Sand characterisation. The following tests were performed on the sand samples: - chemical analysis - sieve analysis

Additionally, we offer testing services as well. ... Chromite Sand Chromite Sand is a naturally occurring mineral consisting primarily of the oxides of chrome and iron.
