Nov 25, 2019· The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the world's total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The U.S. makes the cut, as well, with two mines among the top 20.
ducing copper: the direct and indirect costs in-curred in mining, concentrating, smelting, and refining copper. They include transportation to the mill, smelter, and refinery, and metallurgical processing of the byproducts. Some estimates of operating costs also include the freight charges for transporting the refined copper to market.4 Direct ...
complexities associated with such mining) • Intricate infrastructure • Increased electricity costs (for cooling deep underground shafts) • Overall increase in overhead and maintenance costs In the case of some metals, like platinum, depth of mining is rising as metal available at shallow levels has for the most part already been extracted.
hydrometallurgical process for processing copper sulphide concentrates to metal. The basic concept of this process is to allow processing of concentrates on site at the mine, to minimize downstream costs, including freight on concentrate. Although it has outstanding environmental features, the CESL Process .
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Copper was first used in ancient Britain in about the 3rd or 2nd century BC. In North America, copper mining began with marginal workings by Native Americans. Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600.
In the case of copper, energy costs in most countries were about 30–35% of total expenses of smelters and refineries, and labour and other costs the remaining 65–70%. These figures agree with the cost structure suggested by ECORYS (ECORYS, 2011).
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
Mining, Processing and Development. Mining could utilize open pit methods. Ore production is designed to increase from 29,000 to 52,000 tons per day, with an average rate of 41,000 tons per day at an overall waste-ore ratio of 2.3:1. Ore will be crushed in two-stage crushing and then heap leached with sulfuric acid solution.
