Status and prospects of foreign mining - in the Balkans

,[link widoczny dla zalogowanych], Extraction of radioactive elements, clean water and to extract some elements from the exhaust gas, separating out the carbon hydroxide and so on. Natural zeolite used in agriculture, animal feed additive, soil conditioner, separation of heavy metal ions to reduce their levels in plants, also used as structural materials and more. Finely ground clinoptilolite dehydration can be used as a plastic filler (added amounted to 70%). In recent years, also used in the production of zeolite detergents, cosmetics and medicines. Clinoptilolite reserves are 2.065 billion t (including 722 627 000 t for industrial use.) 6) piezoelectric quartz crystal products for audio equipment, wireless phones, and electronic cash registers and other stopwatch, quartz glass, transparent parts for aircraft, thin as the instrument, optical connectors, strong light source covering, as well as fiber optic cable , and utensils. The total reserves of 360000t (including 220O00t industrial). 7) decorative stone industry reserves are as follows: 162,001,113 marble, limestone 32 million, angular rock 27 million, 29 million granite, gabbro 5,900,000 m,[link widoczny dla zalogowanych], rhyolite 25,001,113. Decorative stone mining and production of state-owned trading company by l4 and other private companies to achieve. In 1997 about 61,113 stones mined, produced 71_8 million in various types of stone. 2010 - 2015 period is expected to produce l0 ~ l2 million m and about 1.2 million stone blocks. In the enrichment and production of minerals is extremely difficult question is will produce large quantities of waste. For example, the annual output of coal waste in 1996 alone 225 792 000 t, while those from non-metallic minerals, cement companies and neutral structures is much less waste of materials, about 5.1 million t. Useful products is 17 million t. In short, Bulgaria is relatively well-developed mining industry. The country's copper and polymetallic ore production prominently in the European position. In Bulgaria from a planned economy to a market economy, the Bulgarian mining industry experienced a very difficult period, especially in underground mines and the coal mining industry. In addition to coal mining industry, mining industry, but is being implemented partially or fully privatized. Bulgarian Parliament approved a natural resources law, provides for attracting foreign investment to the mining industry conditions. 31 Overview 3 Romania Romania owns a wide range of useful minerals underground (pit coal, lignite, new lignite, gold silver, lead, copper,[link widoczny dla zalogowanych], zinc, iron and manganese ore, rare metals and radioactive ore, bauxite, sulfur and rare non-metallic minerals), almost the entire region located in the territory. The total geological reserves of useful minerals over 12 billion t, refined with modern technology can be used after treatment of mineral products worth about 250 billion U.S. dollars. Romania's mineral resources, geological mining conditions that have adverse and complex mineralogical characteristics, namely: low calorific value of coal, ore, low content of useful components, complex geological structure and hydrogeological conditions poor. The end of 1997 has formed an autonomous region 7 (RA.) mining organizations, namely: HuilaPetrosani (pit coal),[link widoczny dla zalogowanych], LignitTarguJiu (lignite), CarbunePloiesti (coal), CupruDe-va (copper), PlumbsiZinmcBaiaMare (lead and zinc) , Met-aleRareBucuresti (rare) and SareBucuresti (salt). These agencies have 157 mines and 111 quarry, 7316} II in February 2001 the whole stack of the first trade of the home concentrator and mining companies, trading companies and conduct geological research activities related to the trading company. Mining industry is still an important branch of the Romanian economy. As supply and demand variability, the mining industry can not be selected as the mining industry to adapt to a market economy so quickly. Romania's economy is currently, on the whole are experiencing some constraints, mainly resulting from poor access to finance due to lack of investment capital and working capital deficiency. Romania, short term strategies and policies throughout the industry, from Romania, the idea of integration with the European Union, in the following period the state is to some economic behavior and economic behavior of European countries similar or close. 3.2 The estimated resources of Romania has a large geological reserves of solid minerals, 30 - 40 billion t of lignite, pit 1.5 billion t of coal,[link widoczny dla zalogowanych], 40 billion t gold silver, 900 000 000 000 t copper, 4O million t of salt and 400 million t bituminous schist. Economic effectiveness in a context of sustainable exploitation of 3O ~ 100a. Although most deposits in reserves can be mined, very difficult to achieve because of difficult geological conditions and current economic indicators. 3.3 beneficiation of mineral deposits in Romania have been mined grade of the price of metallurgical
