Copper Environmental Profile
copper mining: surface and underground mining. Due to copper being spread in relatively low concentrations over large areas, surface, or open-pit mining, is the predominant mining method for copper in the world. After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical.
Platinum Mining and Refining | Education
Mining platinum in placer deposits is a relatively simple process. Dredges scoop the platinum-bearing sand or gravel from riverbeds or mining pits. The material is washed until platinum grains or nuggets are captured and pulled from the surrounding material. Sperrylite, or platinum arsenide. Photo from Thomas A. Loomis, Dakota Matrix Minerals.

Innovations: Introduction to Copper: Mining & Extraction
Copper Applications in Metallurgy of Copper & Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.
Recovery of Copper by Solution Mining Methods
A Brief History of Copper Recovery by Solu-tion Mining Methods As early as the 1670, copper-bearing mine waters at the Rio Tinto mine in Spain were known to chemically precipitate copper onto iron (Arbiter and Fletcher, 1994). This process became known as the "cementation process", which is apparently derived from the Spanish word

Copper Mining and Extraction: Oxide Ores
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
Geology of Copper | Properties, Mining, and Formation of ...
Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.
Copper Mining Process | Information | New Mexico | Basics
The process of mining copper begins with drilling and blasting. Large drilling rigs bore a carefully designed pattern of holes approximately 12 inches in diameter and 60 feet deep into the rock. The holes are filled with an explosive compound of fuel oil and ammonium nitrate which blasts thousands of tons of ore in a single detonation.
