Effect of ChromiteSilica Sands Characteristics on

Chromite ladle filler sands are one of the most widely used ladle filler sand. Several operative variables and materials characteristics affect the performance of the sands. Three sets of chromite ladle filler sands were selected and researches were focused on the sintering behaviour and per formance of the sands under operative conditions.

associated with chromite sand deposits. Materials can also gain weight due to oxidation reactions. This is especially true of chromite sands when tested in an oxidizing atmosphere such as a typical laboratory furnace. Typical foundry grade chromite sands will show a weight gain of 0.5 to 1.0 in a standard LOI test.

Overview

The grade of a typical heavy mineral sand ore deposit is usually low. Within the 21st century, the lowest cutoff grades of heavy minerals, as a total heavy mineral (THM) concentrate from the bulk sand, in most ore deposits of this type is around 1% heavy minerals, although several are higher grade.
Of this total heavy mineral concentrate (THM), the components are typically

Chromite

Overview

Chromite minerals are mainly found in maficultramafic igneous intrusions and are also sometimes found in metamorphic rocks. The chromite minerals occur in layered formations that can be hundreds of kilometres long and a few meters thick. Chromite is also common in iron meteorites and form in association with silicates and troilite minerals.
The chemical composition of chromite is Fe Cr 2O4. Chromite, when presented as an ore, or in massiv
