Apr 14 2017 Arizona leads the country in copper production and is one of the primary sources of molybdenum as well In fact Arizona’s molybdenum wealth is largely related to its copper wealth as the molybdenum is recovered as a byproduct of the copper mining Mineral Industry Value $5 56 billion Percent of U S Total Value 7 45.
The four major steps in the production of marketable copper are mining concentrating smelting and refining In a few instances however leaching takes the place of concentrating smelting and refining At present although considerable leaching and direct smelting ores are produced the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger.
Extraction and refining The extraction of copper from ore is normally carried out in three major steps The first step mineral processing is to liberate the copper minerals and remove waste constituents—such as alumina limestone pyrite and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
Nov 25 2019 The nci mine in Arizona is the largest copper mine in North America Operated by Freeport McMoRan the mine is jointly owned by the company (72 ) and affiliates of the Sumitomo Corporation (28 ) nci operations began in 1872 underground mining began in 1881 and open pit mining began in 1937.
Stage 3 Roasting At this stage of the process the chemical reactions begin They convert the copper minerals into copper metal We can illustrate the types of process using the example of chalcopyrite – CuFeS 2 From the formula it is clear that iron and sulfur have to be removed in order to produce copper.

One is that it is a smelter copper specimen from one of the Arizona processing plants which would explain the tag that was associated with it I have seen some smelter specimens from White Pine in Michigan but none this large.
In this process copper ore is mined crushed ground concentrated smelted and refined The mining crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper bearing minerals from it.
Copper is usually found in nature in association with sulfur Pure copper metal is generally produced from a multistage process beginning with the mining and concentrating of low grade ores containing copper sulfide minerals and followed by smelting and electrolytic refining to produce a pure copper.
