Abstract:
The Republic of Macedonia, in which structure participate different lithological complexes and various formations of different ages, in terms of minerageny, is rich with different genetic types of silica raw materials. Quartz, quartzite, quartz sandstones and secondary igneous quartzite are treated as a special group of raw materials due to their specificity, application area and the manner and conditions of their formation and the types of deposits in which they appear. The quality of silica raw materials depends on presence of harmful matters (feldspars, mica, pyrite, limonite etc.). Studying of silica resources on the territory of Macedonia suggests a promising development of these raw materials, primarily because of their applications in many industries, such as telecommunications, optics, medicine etc.
