Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main process streams; one for sulfide ores and the other for ore that is being weathered to oxidize sulfides the so-called oxide ores. All ore in the pit

OPERATIONS MODELING AND ANALYSIS OF OPEN PIT COPPER

Open pit copper mining plants usually comprise two major components, the open pit mining operation and the copper ore enrichment plant. An open pit copper mine is an excavation or graze made into the sur-face of the ground for the purpose of extracting ore.

Everything You Need To Know About Open Pit Mining ...

01/11/2018  Open pit mining is one of mankind's greatest achievements in the ongoing search for precious ores such as copper, silver, iron, and gold. It describes the process of systematically excavating land and digging out the rocks and minerals in search of metallic ores and removing them via borrow or open pit. The open pit mining method (also known as opencast, open-cut, or strip mining

Open pit machinery can also be used for other purposes such as civil construction, whereas underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines

Surface mining planning and design of open pit mining

09/01/2016  Scrapers are sometimes used in special situations. Large bucket-wheel excavators of the kind used in European coal mines have not been applied to metal mining, because this equipment is best adapted to softer bedded, relatively flat-lying strata. Many factors govern the size and shape of an open pit. These must be properly understood and used in the planning of any open pit operation.

Copper extraction - Wikipedia

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 ore must usually be beneficiated (concentrated).
