Uzbekistan Bravo Yi Sike (ΗавойиÑк) Mining and Metallurgical Company (referred to ÐГМК mining and metallurgy company) is one of the world's top 10 uranium production Jinhe company, is the largest mining and metallurgy enterprises in Uzbekistan. The existing staff of 60,000 people. Gold and uranium are the company's main products. The company consists of exploration, mining and ore processing departments that produce uranium octaoxide and pure gold. Further mined phosphate ore.
The Ð“Ð°Ñ€Ð°Ñ„ÑˆÐ°Ð½Ñ gold branch of the ÐГМК Mining and Metallurgical Company is the second largest gold producer in the world. The company entered into a joint venture with Newmont in the United States in 1995. The company has two water and metallurgical plants. The No.1 water smelting plant in Unoyi City handles the off-surface ore of the Mulongtaiwu deposit with a treatment capacity of 700,000 tons of ore. No.2 water metallurgical plant open-pit mining ore, the current mining depth of 450m. In 1991, 20 million tons of ore was processed. The gold grade of ore is relatively low, 0.7 to 1.1 g/t, but 50% of waste rock can be removed by pre-selection by automatic picker, and the grade of ore gold can be increased to 1.1 to 1.89/t. ÐГМК Mining and Metallurgy Company's Uchigku Dukeke (УчкудукÑк) branch management No.3 water smelting plant, water smelting plant processing oxidized ore, the annual processing ore volume is 2.5 million tons.
ÐГМК Mining and Metallurgy Co., Ltd. uses the underground leaching method for drilling uranium mine with good economic benefits and good environmental protection effect. A drilling underground leaching system has been established in two deposits. The ore is pre-oxidized by the oxygen-containing air, and the uranium is leached with a weak acid solution, and the leachate is pumped from the underground borehole into the water smelting plant to produce the finished uranium octaoxide. The mine can be leached underground for 15 to 20 years.
The ΚыÑылкумÑк phosphate branch (referred to as ΚΦΚ) handles the phosphate ore of the D’Oroy-Saldarinsk deposit. The deposit has an ore reserve of 303.6 million tons and a phosphorus pentoxide reserve of 57.7 million tons. It can guarantee the use of agriculture in the Republic of Uzbekistan for 100 years. In 1997, a non-selected powder ore mine with an annual processing capacity of 300,000 tons and 16% to 18% P 2 0 5 was built. In 2002 we built a production of phosphorus ore beneficiation plant. The ore processing plant processes 1.5 million tons of ore annually. The concentrator uses a dry beneficiation process. These include selective mining, radiation sorting, crushing, drying, grading, dust removal, and shaft furnace roasting (Fig. 1) to obtain a phosphate concentrate containing 26% to 28% P 2 0 5 .
