Metal Mining in Peru Review 1993
t / a raised to 3OOOOt / a, and correspondingly increase the production capacity of cadmium and sulfuric acid in order to improve the recovery of zinc and cadmium, is preparing to modernize. wMElO a 03l8 (Niehui Cheng) in shares of privatized companies Condestable mining production of copper last year, 4401t. Is planning to privatize state-owned mining company in 1993 from CentrominPeru owned seven mines and smelter were produced before Rao Royal 88618t, zinc 265437t,ugg boots sale, silver 421t.

Buenawntura Peruvian mining company is still the largest private producer of silver, silver output last year 134t, the same period also produces lead 299ot, copper 789t. Buenaventura Mining Company, a subsidiary of ~ copampa Arequipa region in a gold and silver mining gold 264t, silver 56t. Southern Peru Copper Company claims that in 1993 silver production from 106t, to become Peru's second largest manufacturer of private banks. Second place from the front of the Arcata silver mining shares in the company's output last year 103t. In 1993, Asarco Mining Company,ugg stiefel, a subsidiary of Northern Peru, northern Peru, a company from the underground mine production of zinc 16951t, 5416t of lead and silver 79t. Former state-owned company HierroPeru company (sold to China in 1992, Shougang) operates only in Peru - Block iron ore. Last year, production of crushed 4Mt. In 1993, Peru's gold production increased by 44, a total of up to 23052kg. Gold exports 21450kg, worth 238 million. Newmont Mining Corporation by the United States, Buenawn-tuta mining companies and Cedimin (France BRGM company registered in Peru, a subsidiary) established yanacocha mining company claimed last year's gold production is 2608kg, which became the largest gold producer in Peru. WME10 ---- 0319 (Niehui Cheng) (continued from page l) of the cobalt layer ore field structure of mining technology and possible solutions. The structure of existing programs and may be the findings of foreign experts to compare. Such as D. Dr. Calder Hall (USA) proposed the recovery of heavy lOOt unit,uggs ireland, which along with the eight tracks move with the surface drilling. Track not only the use of mobile units, and can crush crushing ore. Crawler traveling device installed in the back of the cutting head, the broken ore suction pipe. Unit F Mount inches to 13X8m, installed power of 900kw. The program is very similar to the above programs, but many disadvantages, such as: the lessons with other possible turbidity; save the limited capacity of the slopes E} and may cause unwanted depleted soil mixed with calcium phosphate ore. The second research direction is to use hopper system,ugg botas, elevator rose only large components shipped to the ship. Meng Tian Shanxiong (Japan) proposed by the buckets of ore endless rope recovery system, the system known ore and mining systems similar to tuberculosis, which is characterized by scraping bucket structure. Russian collection unit production capacity is not less than 40t / h and no more than 15ot / h. Ore pipe elevator is hydraulic elevator and a special mesh in the pipe transport tube elevator. Both are also in the boat transport operation can improve the extraction efficiency of operations. Calculations show that, in order to mine the coal with diamond ore, appropriate for the construction of a loading capacity of the production capacity of 25000t Self-collection ship. Not only can gain from the current sea of metal, you can also get energy. Is well known that the generation of mining engineers have not been evaluated high-grade zinc, copper and other metals of the rupture zone of sulfide ore, there is hot water, \Analysis showed that the physical state of water depends on this smoke with a \fuel - hydrogen with oxygen and salt.
