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. The oxides are smelted to produce matte, which then undergoes several refining processes.

Read MoreThe average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore
Read More2010-12-21 The copper extraction process begins at an open cut mine where Copper Ore is blasted and removed via Excavators and Tip Trucks. The ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor. When the crushed ore falls onto the
Read MoreThe world’s largest copper mine is the Escondida mine in Chile which is owned by Rio Tinto and BHP Billiton. In 2017 it produced 772 kilo tonnes of copper concentrate; and since opening 25 years ago, it has processed more than 2 billion tonnes of ore. Investing in copper and uses of copper

The copper extraction stage is the key stage to improve the grade of copper ore.
Read MoreAn ore reserve is the part of the mineral resource that can be economically profitable to mine (i.e., there is enough valuable metal to be worth removing it and extracting it from all of the surrounding rock). After a deposit has been identified as an inferred, indicated, or measured mineral resource, it is
Read More2019-8-30 The objective of the leaching cycle is the recovery or extraction of a majority of the copper content in the first leaching period. The remaining copper will be re-worked after a new lift of 18 to 20 feet of fresh ore is placed on top and leaching started again.
Read MoreCopper ore extraction by the Carlota mine is by conventional methods typical for open-pit metals mines, i.e. the ore is mined by blasting and then is transported by haulage trucks. In 2018 mining re-commenced in the Eder South area.
Read MoreThe X-MINE project supports better resource characterisation and estimation as well as more efficient ore extraction in existing mine operations, making the mining of smaller and complex deposits economically feasible and increasing potential European mineral resources (specifically in the context of critical raw materials) without generating adverse environmental impact.
