Dolomite in Glass Industry Earth Minchem

High-grade dolomite with as low Iron and Silica content as possible is required by the glass industry. Glass grade dolomite is typified by its purity and consistency. Dolomite is a double carbonate of calcium and magnesium (CaCO3, MgCO3). The chief undesirable impurities are iron followed by chromite, manganese, vanadium and lead, all of which may cause defects in the float glass or color glass. For

Float glass is a mechanically stable glass that can be cut and handled with little breakage. It is most commonly used for building, automotive and solar-energy applications. It is made via float processes. The base network modifier function of CaO and MgO is complemented by the up to 5% share of magnesium oxide. Magnesium oxide is supplied by dolomite and offers a wider processing

Dolomite (mineral) - Wikipedia

Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smeltingof iron and steel. Large quantities of processed dolo

Glass is an environmentally-friendly product used for building, packaging and technology. It is made from silica sand, soda ash and limestone and/or dolomite. The oxides from these natural minerals form the glass, solidify it and enhance its major chemical and physical properties.

Dolomite (mineral) - Wikipedia

Large quantities of processed dolomite are used in the production of float glass. In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a magnesium source. Dolomite is also used as the substrate in marine (saltwater) aquariums to help buffer changes in the pH of the water. Calcined dolomite
