Uzbekistan Alma Lautrec (Ðлмалык) Mining and Metallurgical Company (referred to ÐГМК Mining and Metallurgical Company) from 1949 to develop rich Kula Ming mountains multi metal deposit. Built in 1955 lead zinc beneficiation plant. In 1961, the copper and molybdenum concentrator was put into operation. Recently, ÐГМК Mining and Metallurgy Co., Ltd. is a joint venture with mining, mineral processing and smelting plants. The company recovers 13 useful elements from ore: copper, zinc, cadmium , gold, silver , sulfuric acid, copper concentrate, molybdenum concentrate, selenium , tellurium , copper sulfate, zinc sulfate, etc., is researching recovery from molybdenum concentrate 铼 and 锇 . The copper-molybdenum deposit of the ÐГМК mining and metallurgical company is located in Karimal (Калъмакыр) and SareÄécu (Сары-Чеку), and the lead-zinc deposit is located in 奇ч-Кулач. The Karimal and Sarececu copper-molybdenum deposits are all mined by open-air method. In 2001, the amount of mined ore was 23 million tons and 2.48 million tons respectively. The Uchikuraki lead-zinc deposit is also exploited by open-air mining. In 2001, the ore mining volume was 23 million tons. The copper beneficiation plant was designed by the Mihanopur Concentration Research and Design Institute and was commissioned in 1961 to process the ore of the Karimal and Sarecheku copper-molybdenum deposits. At present, it mainly deals with the ore of the Carimaral deposit. The concentrating plant consists of two workshops, coarse crushing and medium fine crushing. The total processing capacity is 3000t/d. The grinding and floating main car of the concentrator is composed of 10 systems. The ball mill specifications are 3.6m×4m, 3.6m×5m and 4.5m× 6m. Using flotation volume of 6.3m 3, 12.5m 3 and 16m 3 flotation cells. Copper concentrate and molybdenum concentrate were obtained by copper-molybdenum mixed flotation-copper-molybdenum separation flotation process. After being concentrated and dried, the copper concentrate is sent to the company's copper smelter for smelting. The molybdenum product is sent to the refractory metal smelter for processing. The tailings are transported by water to the tailings dam at 12km from the concentrator. The lead and zinc concentrator was built in 1954. The lead-zinc mixed flotation-lead-zinc separation flotation process is adopted, and the obtained zinc concentrate is processed by the zinc smelting plant of the branch, and the lead concentrate is exported. The crushing workshop of the ore dressing plant consists of two medium crusher jaw crushers and fine crushers . The grinding and floating workshop consists of six systems. The mixing flotation plant uses 16 3.2 m × 3.8 m ball mills and a 3.2 m 3 flotation machine. In recent years, the ore dressing plant processed the ore of the Sarecheku copper-molybdenum deposit, and the obtained copper-molybdenum mixed concentrate was treated in the copper-molybdenum separation circuit of the copper-molybdenum concentrator of the ÐГМК mining and metallurgical company.
