A technology was developed for obtaining glass silica based on fractionated cullet of colored container glass and the waste from enrichment of ferruginous quartzites of the Kursk of Magnetic Anomaly (KMA) at the Lebedinskii Mining and Processing Combine [Lebedinskii GOK]. By using the waste from enrichment of ferruginous quartzites of the KMA the sintering temperature could be lowered and the quality of the glass raised. The obtained glass silica exhibits high performance and aesthetic properties. Key words: glass silica, waste from enrichment of ferruginous quartzites of KMA, colored container glass cullet, strength in compression, microhardness.
Glass silica is a quite effective and long-lasting facing material. The conventional technology for fabricating glass silica calls for pouring the first layer of granular glass, mixed with quartz sand, into a mold to 3/4 height and a second layer of colored cullet. The second layer in the mold is likewise poured according to a stencil in order to create a definite or textured pattern on the front surface. The technology calls for glass granules with a definite fractional composition to be prepared beforehand. Currently, three basic methods are widely used to prepare the fractionated glass. In the first method a strip of opacified glass is formed from the molten glass, hardened by thermal shock on cooling with water, and crushed and ground in rolling or ball mills. The second method consists in granulating a stream of molten glass in water. The third 1

method calls for grinding different wastes from glass production [1]. It should be noted that the classical technology employs raw materials that are in short supply, and it is quite energyand labor-intensive. By replacing the raw materials with waste from the mining industry and glass household waste it will be possible to substantially reduce the production cost of the final product [2 – 6]. It is proposed that the wastes from the enrichment of ferruginous quartzites of the Kursk Magnetic Anomaly (KMA) at the Lebedinskii Mining and Processing Combine [MPC] be used as the basic raw materials. A large part of these wastes consists of quartz and < 10% (by weight) consists of calcite, pyrite, dolomite, aegirine, biotite, and alkaline amphiboles [7]. The chemical composition of the wastes from the enrichment of the ferruginous quartzites of KMA at the Lebedinskii MPC is reflected in Table 1. The chemical composition of the wastes from the enrichment of the ferruginous quartzites of KMA is quite stable (see Table 1). According to the stockpile of wastes accumulated over more than half-a-century history of the existence of the Lebedinskii MPC the KMA can be included among the
