Apr 21, 2016· The first major copper mine in the British Isles emerged at Ross Island, in southwest Ireland, around 4,400 years ago. One of the reasons we know this is that artefacts like bone tools and ...
The ore in the Dexing Copper Mine can be divided into porphyry and phyllitetype ore according to the type of ore body rock. The ratio of ore volume is 1: 3. In the mining area, there are three industrial types of oxidized ore, mixed ore, and primary sulfide ore. The sulfide ore is the main type and accounts for more than 99% of the mass.

The Dexing porphyry copper ore mine is located in the QinHang metallogenic belt between the Yangtze block and the Cathaysia block. It is a giant porphyry copper mine in China, including 3 ore districts: Tongchang, Fujiawu and Zhushahong. Our analyses of Re in molybdenite indicate that the oreforming material of the copper ore deposits in Dexing should be mainly mantlederived.
Noted centers of mining include Dexing (copper) and Dayu County (tungsten). Jiangxi Copper is China's largest copper producer, and manufactures 340,000 tons of copper annually from its mines, which include the Dexing and Yongping pits and the Wushan, Jiangxi, underground mine.

Feb 03, 2014· Detection of nif genes in acid mine drainage. To obtain as many nif genes as possible in AMD environment, we performed metagenomic sequencing of the AMD sample from Dexing Copper Mine in China. Metagenomic sequencing yielded a total of 640,892 reads and 300 Mb of raw sequence with the average length of 471 bp.
The wastewater source of 4# tailing pond in Dexing copper mine consists of alkaline flotation pulp and acid mine drainage (AMD) from the nearby opencast mine. Therefore, the heavy metals in tailing ore are very likely to be released due to acidification from AMD.
In addition, the Dexing Copper Mine in Jiangxi Province heap leaching plant, under the condition of more than 90% of primary chalcopyrite and containing copper waste rock grade %, effectively realized the bacterial leaching of copper extraction. Xinhai is a domestic and .
The study area was located at the Dexing Copper Mine, Jiangxi Province, China. First, the data preprocessing for the Hyperion image was conducted, including bands removal, radiometric calibration ...
Samples were collected from AMD in Dexing Copper Mine, China. The environmental DNA was extracted and used to construct a fosmid library. The library collection contained in total 7,776 largeinsertion clones. The genomic fragments cloned in the fosmids had a size of between 30 and 45 kb.
BQE Water established a joint venture with Jiangxi Copper Company to build and operate water treatment plants using BQE Water technologies. At the Dexing Mine, lowgrade ore waste dumps generate copperladen acid mine drainage. To treat the mine water, a ChemSulphide® plant was .
Waste rock and tailings of a mine generate acid mine drainage due to oxidization during longterm stacking, and this may cause serious harm to the environment. 1yearold, 5yearold, 10yearold and 20yearold waste rock of Dexing Copper Mine are chosen in the experiment for acid generation research. The static evaluation result shows that the 4 types...
Mar 14, 2009· Environmental impacts of acid mine drainage (AMD) from Dexing Copper Mine, the largest open pit copper mine in Asia, on Le An River were well documented 10 years ago. However, ore production of the mine has increased fourfold and the contamination situation of the river now is unknown. Our studies indicated that heavy metal concentrations in riverwaters (dissolved), suspended .
