Sillimanite is an Alumino-Silicate material. It is obtained through high temperature, aluminium rich regions.

Zircon, normally a transparent beige coloured glassy mineral, finds its place in many an industrial application worldwide.

Barite, also called barytes or heavy spar, the most common barium mineral, barium sulfate (BaSO4).

Quartz, widely distributed mineral of many varieties that consists primarily of silica, or silicon dioxide (SiO2).

Coal Slag is boiler slag, which is a recycled product from coal burning plants.

Copper slag is mainly used for surface blast-cleaning.

Fused Alumina is made in electric arc furnace by passing a current between vertical carbon electrodes. The heat generated from this procedure melts the alumina feedstock.

Ferrosilicon is an alloy of iron and silicon with an average silicon content between 15 and 90 weight percent. It contains a high proportion of iron silicides.
