The HCA Mountain Minerals silica operations mines and processes high purity glass grade silica sand for diverse industrial applications. Our SILWITE® products have a purity ranging from 99.15% to 99.55% SiO2, well exceeding the requirements for silica sand ceramic grade and foundry grades. Our products have extremely low iron oxide content, and therefore will not interfere with the color of the end products.
The SILWITE® product line is used in several industrial applications such as: feedstock for glass manufacturing, foundry sand, additive in refractory cements and ceramics, as well as a functional filler/extender for high durability paints.
SILWITE® fine, white sands are used as bunker sand for golfing, to provide the pure white look that is very much in demand. We count among our customers many prestigious golf clubs in Western Canada, including one customer located in Hawaii.

Particle Size - HCA Mountain Minerals has achieved a 100% screen cut product. The plant is geared to supply flint grade glass sand to particle sizes between 30 and 140 mesh with zero oversize and not more than 5% fines.
Iron Level - Iron in glass sand is also a critical factor. Specifications allow for a maximum of 0.0355%. Because of the nature of HCA Mountain Minerals' silica deposit and the Company's proprietary processing, this ranges as low as 0.0070%.
