Copper mining type

There are many types of copper ore found throughout the world. Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. While the copper market is gaining momentum, it is a good time to look at the copper mining champions in terms of copper grade in ore reserves. The copper deposit was discovered in 1920 and mining operations began in 1970. The Andina mining operation consists of Río Blanco underground mine and the Sur Sur open pit mine exploiting the Río Blanco deposit. The mine produced 249,861t of fine copper and molybdenum in 2012.

Each year this mine produces 475,000 tons of concentrated copper ore (28% Cu) , Various rock types of different colors may be dumped in the same place,  Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides. Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017 the United States produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US.

Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste; tailings, dump and heap leach wastes, and waste rock and overburden. The amount of marketable copper produced is small compared to the original material mined. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining The major types of zinc ore deposits are generally found to be sediment-hosted, volcanic-hosted, intrusion-related, Broken Ore type or Mississippi Valley Type. The Zinc Mining Process. The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earth’s surface. The two main types of mining are surface mining and underground mining. Mining is further divided into several other categories including room and pillar mining, slope mining, block caving, quarrying, open-pit mining and in situ mining.

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. There are two main types of copper ore of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined, though they are processed in different ways. Copper sulfide ores are typically the most profitable types of copper ores to mine. Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste; tailings, dump and heap leach wastes, and waste rock and overburden. The amount of marketable copper produced is small compared to the original material mined. Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living. Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity - mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper and zinc) and bronze (copper, tin, and zinc). There are many types of copper ore found throughout the world. Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper.
