TECHNICAL EXPERTISE

MINING

The Quartz Corp has >10 million tonnes of High Purity Quartz resources in Spruce Pine.

SIZING

The Quartz Corp uses rod mills to crush the mined quartz sand, and screens, allowing us to precisely size the material to a variety of different PSDs.

FLOTATION

Flotation is the first key purification step our quartz goes through, and uses chemicals and air to remove traces of non-quartz impurities such as feldspar mining from the mine.

LEACH

The Quartz Corp uses strong acids to remove any remaining surface inclusions and impurities in the quartz grains. In a typical leaching process, specially selected solvents are added to selectively dissolve inclusions without harming the desired final product.

CALCINATION

Heating the quartz grains to high temperatures in The Quartz Corp’s state-of-the-art calcination tubes helps to remove any residual organic contaminants and improve the final quality of the glass made with the sand.

MAGNETIC SEPARATION

Speciality magnetic separation is employed by The Quartz Corp to ensure precise chemistry of the final product.

PACKAGING

All shipments of The Quartz Corp’s high quality quartz are tested and given an individual certificate of analysis, meaning customers can be assured they receive consistent product every day.

CHLORINATION

The Quartz Corp's highest purity product goes through a high temperature chlorination step, which makes the material ultra-high purity for use in the highest tech markets.
