mill creek dolomite | inter-rock minerals
Mill Creek Dolomite owns and operates a high quality, glass grade dolomite quarry and plant in Mill Creek, Oklahoma. Although most mined dolomite in North America is used in construction aggregates, the purity and decrepitation characteristics of the Mill Creek dolomite deposit allows for the production of higher value products.
Mill Creek sells its products into specialty markets for dolomite, principally the glass, roofing materials, and agricultural lime (aglime) markets. About 70% of Mill Creeks sales volume is to the glass industry. Flat glass manufacturers value the purity, low decrepitation, and the consistency of the concentration of calcium and magnesium in Mill Creeks dolomite. The filler market, primarily for asphalt shingles accounts for about 20% of Mill Creeks sales volume and the remaining 10% of sales are to the aglime market. Mill Creeks aglime products are soil additives that reduce soil acidity and provide a high purity source of calcium and magnesium for plants. More information on Mill Creeks products is available at www.mcreekdolo.com.
Mill Creek is ideally located to serve the large concentration of glass and asphalt shingle manufacturers in Texas, Oklahoma, and eastern Kansas. Almost all of Mill Creeks product shipments are by truck.
Mill Creeks plant has been recently upgraded, primarily to expand capacity to allow for increased sales to the glass industry. Capital improvements included the rebuilding a crusher and the purchase of new mobile crushing and screening equipment.

Mill Creek supplies the glass industry with a line of uniform composition, ultra high purity, and low decrepitation glass grade products. Our glass grade dolomite is a high purity source of calcium and magnesium oxides for float glass, container glass, tableware flint, and glass fibers.
The dolomite acts as a fluxing agent to assist melting and adjust the melt viscosity. Additionally, it imparts increased durability and strength, reduces devitrification, and provides a more enduring luster.
Mill Creeks filler grade dolomite is a low silica crystalline mineral with uniform particle size distribution and consistent chemical composition. The high bulk density and sub-angular shapes provide a cost-effective structural function in asphaltic and bituminous based materials by increasing loading rates.
Aglime improves the physical, chemical, and biological properties of soil. For most crops, the optimum soil pH for maximum plant growth and fertilizer efficiency is in the range 6.0 7.0. Liming soils to this range can dramatically increase crop and forage yields and also improve the performance of certain herbicides.
As a fluxstone, the chemical and metallurgical grades improve refining efficiency in iron smelting, small-scale cupola fluxing, and non ferrous sintering. This low silica dolomite is also an excellent loose refractory for bank doors and hearth bottoms. As a magnesium source, Mill Creeks products are an effective magnesia and magnesite substitute in ceramic frit and ceramic wares manufacture and process batching.
