This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

History of Morenci copper mine. The Detroit Copper Company started mining at Morenci in 1872. Copper Queen Consolidated Mining bought the property in 1885, with the company name changed to Phelps Dodge in 1917. Phelps mined underground until the 1930s, converting to an open-cut operation with rail haulage in 1937.
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, …
Copper deposits come in two main types - oxides found near the surface and sulfides found deeper underground. While both contain copper, their geological origins and extraction methods differ significantly. Understanding these differences is key for investors evaluating copper mining projects.
However narrow vein drill rigs are designed less to accommodate height challenges and more for the general navigation of geologically complex mine spaces with widths less than 3-6m. Narrow vein deposits contain large amounts of gold, tin, copper, lead, and zinc that narrow vein drill rigs allow us to access and utilize. Secondary Breaking Drill ...
