About – Chesapeake Minerals

About Us

Chesapeake Minerals is a division of Stewart Companies, a mid-Atlantic-based group of diversified businesses that employs over 1600 people across multiple markets. The Stewart Companies have active mining operations in Maryland, Pennsylvania and Colorado, where sand, gravel and stone production exceeds 3.2M tons annually.

Our Process

Chesapeake Minerals uses select grades of quartz gravel supplied by York Building Products Co., Inc.’s adjacent Belvedere plant where more than 10,000 tons of alluvial sand and gravel are processed daily.

Select quartz gravel is crushed, washed and classified into multiple low-iron quartz commodities. Glass sand (40 x 140 US Mesh) is then dried and separated from remaining iron-bearing magnetic minerals to make an ultra-low iron glass sand (Principio White). Following magnetic separation, our glass sand is 99.998% SiO2. A grinding mill will be added to the circuit and commissioned in fourth quarter of 2023 to produce high purity silica powders to customer specification.
