Copper Mining Using Acidothiobacillus microbewiki
Either through stripmining or blasting, raw ore is obtained for extraction of copper. Heap Irrigation. The ores obtained from mining are crushed and piled up to 10 meters high atop plastic irrigation pads, whereupon water seeded with acid, called the lixiviant, is irrigated through the heaps and collected (Fig. 2).
Introduction of Copper Ore Dressing Process Xinhai
Copper ore usually refers to mineral aggregate in the nature that can be used to extract metal copper, generally copper sulfide and copper oxide. Copper minerals in nature mainly include pyrite, chalcopyrite, tetrahedrite, chalcocite, azurite, malachite, etc. Chalcopyrite is the main mining copper ore, followed by bornite and chalcocite.

We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. Mining for Copper Bearing Ore. There are two categories of copper oresulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment.
Copper mining. Introduction. SchoolScience.co.uk
Mining metals: Metals are often found as compounds in ores.An ore is a rock or mineral that has enough metal in it to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1000 kg of ore.
Copper extraction refers to the methods used to obtaining 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.

INTRODUCTION TO MINING 1.1 MININGS CONTRIBUTION TO CIVILIZATION Mining may well have been the second of humankinds earliest endeavors granted that agriculture was the rst. The two industries ranked together as the primary or basic industries of early civilization. Little has changed in the
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit.
Copper Ore Processing Methods
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 directsmelting ores are produced, the bulk of the copper ore mined is concentrated.

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.
Introduction to Spectroscopy: Analysis of Copper Ore
Introduction to Spectroscopy: Analysis of Copper Ore Introduction: Thousands of years ago, copper was abundant enough in quantity that it could be found on the Earths surface. Prospecting for copper then was relatively simple. Recently, increased demand for copper resulted in numerous mines, and the search for copper ore is now very competitive.
TENORM: Copper Mining and Production Wastes US EPA
Copper is used in many different industries, including building construction, transportation, electronics and consumer goods. Minerals are concentrated in specific types of geologic formations (ore bodies), which are where mining takes place. These ore bodies may already contain naturallyoccurring radioactive materials (NORM).
Copper Mining and Processing: Processing of Copper Ores
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.
Copper in Africa
Copper is one of the world's most important industrial minerals, and Africa is an important world producer. While output is traditionally dominated by Zambia, South Africa and Katanga Province in the south of the Democratic Republic of the Congo, many African nations contribute to copper production, and many African nations have undeveloped ore resources.

This highgrade ore was shipped directly to the smelter without processing and averaged 5055% copper. Lowergrade ore was sent to the mill for processing. The overall grade was over 12% copper. Mining the outcrop ore at the Bonanza Mine was done by open pit. Underground mining was done in two stages using shrinkage stoping.
