beneficiation英文

1, 3-mining analysis of the value of 1, cost analysis The three-rich mining site visits, the company has completely the mining company's main cost of production outsourced to Wenzhou Jian-feng Mine Engineering Company Limited, on the other three belong to the rich mining operations rather than face-underground mining operations, therefore, mining units The basic cost of the original ore locked. The beneficiation process does not need a large, sophisticated equipment, primarily for ore processing mill and simple facilities, with the company's technology and staff to understand the equipment before and after the Spring Festival each year only to conduct a comprehensive overhaul, and routine maintenance costs low. After investigation, 06 and 07 respectively, the maintenance cost is 06,000 yuan and 10,700 yuan (updated some accessories), and the maintenance costs of both the company's management costs, therefore, the costs could be roughly in accordance with the annual management Together with the proportion of costs together. However, as 07 three-ore mining a large number of outsourcing, and outsourcing of the ore grade is far lower than the three-produced by mining ore grade and therefore, according to 07 estimates the cost is relatively high, and under 06 data The cost estimates were relatively in line with its own three-mining the actual situation. 06 According to financial data and mining of calculations: Main business costs = 2484/11 = 225.8 yuan / ton Cost of sales = 452,000 yuan / 110,000 tons = 4.1 yuan / ton Management fees = (338-100) / 11 = 21.64 yuan / ton (including management fees of 1 million yuan tax resources) 2, sales analysis As the three-ore mining unit of the production costs can be regarded as the basic lock, the only way to have an impact on the operational effectiveness of the metal is the market price changes. The mine ore in the original principal containing zinc, lead and silver, and ore of lead and zinc grade of about 1:4, said the company's future profitability mainly depends on the zinc price fluctuations. Below will combine historical data on zinc, lead and silver price trends do an analysis: 1) lead, zinc prices overall trend analysis According to Non-ferrous Metals Industry Association statistics, China's lead-zinc mine in the mountains, close to depletion of resources accounted for 56.6 percent, a crisis of 23.9 percent, the resources are protected only 19.5 percent, the existing lead, zinc reserves are dynamic exploitation of life assurance Less than 10 years. And the global lead and zinc reserves situation is not optimistic, dynamic exploitation of protection less than 20 years. 2009, the shortage of lead and zinc resources of the state of the market will be more and more attention, lead and zinc prices will be even more outstanding performance. 2) Lead Lead from the past five years and the price of nearly one-year price trend analysis, with the current situation of scarce resources gradually, the current prices can be seen as a low the next few years, that is 13,200 yuan / ton, the high point of 29,600 yuan / Tons, the average price of 21,600 yuan / ton. 3) zinc Zinc from the past five years and the price of nearly one-year price trend analysis, with the current situation of scarce resources gradually, the current prices can be seen as a low the next few years, that is 13,200 yuan / ton, the maximum 35,800 yuan / ton, The average price of 200 million yuan / ton. 4) Silver Silver prices linked with the yellow metal prices, the impact on the international market price factors more. With the U.S. economy slowed, the Fed lowered interest rates a row, the future trend of market confidence in the dollar remains weak, negative remarks gold prices fell slightly. However, due to the recent geopolitical tensions and dollar weakness is still an effective support to gold. And open to the snowstorm, the weather and the impact of the recent earthquake non-ferrous metal prices have driven up the domestic spot price of silver all the way up, recently, China's stock market fell below the continuous line, the market investment hot spots of the precious metal market. Silver prices in the international and domestic double favorable environment steadily increased, the price of silver is expected in the next few years will remain at Wenzhongyousheng situation. Therefore, the silver set may be rough for the low price of 2.5 yuan / g, high point of 4.75 yuan / g, an average price of 3.5 yuan / gram. 中文 » 英语 翻译
