Advantages of method of copper mining

tampakan g copper project mining technology miningmining at tampakan gcopper mine. smi selected openpit mining as the only viable method due to the nature and geology of the deposit. mining activities were planned to include preparation of the site, drilling and blasting of the ore and waste rock. ore and waste rock was supposed to be extracted using large mechanical shovels, excavatorscollahuasi copper mine, northern chile mining technologylying in an area of historical copper mining, the deposit was outlined in 91 after exploration by shell, chevron and falconbridge in the late 80s. the mine was commissioned in april 99 at a cost of 1.76bn. during 04, the project partners completed a 584m expansion programme at the mine, giving it a longterm capacity of 500,t/yr ofheap leaching heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to thetenorm copper mining and production wastes us epajun 07, · there is a broad range of tenorm concentrations in copper mining wastes. mining and extraction of copper by surface or underground methods can concentrate and expose radionuclides in the waste rock and tailings tailingsthe remaining portion of a metalbearing ore after some or all of a metal, such as uranium, has been extracted.. leaching and
