Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two decades of this century, whenopen pit mining, flo tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leachingsolvent extrac
The choice of whether a deposit is developed through mining or insitu is determined by mother nature. If the bitumen deposit is near the surface, the oil sands is mined and sent to a bitumen processing plant. But for deposits that are deep below the surface, bitumen is extracted insitu.

Jul 26, 2018· Dan Johnson, VP General Manager of Florence Copper, Inc. For over fifty years, the Poston Butte porphyry copper deposit near Florence, Arizona, has been on the radar screen of Arizona's mining industry. An estimated billion pounds of copper, hosted in Proterozoic quartz monzonite, lies buried beneath 400 feet of overburden.
However, in situ recovery mining is a possible solution to extract the remaining copper in an environmentally and community sensitive manner. The research focuses on several areas including community acceptance of ISR as a mining technique, mineral characterisation, lixiviant system design and optimisation, and accurate fluid flow modelling.
Mining can be broadly divided into two categories: surface mining and underground mining. Nonentry mining is associated with insitu mining and augering. Each type of mining has numerous variations, depending on the combination of deposit type, rock strength, depth, thickness, inclination, roof, .
Mar 04, 2013· The Gunnison Copper Project is located close to the required infrastructure and its oxide copper resource has the potential to be mined using insitu recovery methods. The Excelsior team consists of experienced professionals with proven track records of advancing projects towards production.
Insitu recovery (ISR, also referred to as insitu leaching or solution mining) may offer such a stepchange approach. ISR refers to the recovery of valuable metals from ore deposits by the circulation of a fluid underground and the recovery of the valuable metal from the fluid at the surface for further processing.
Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained. The leaching process in mining is ...
Method of Insitu leach mining. Insitu leach mining entails pumping of a leachate solution into the ore body via a borehole, which circulates via the porous rock dissolving the ore and is extracted by means of a second borehole. The leachate solution differs according to the ore deposit for salt deposits the leachate may be fresh water into which salts may willingly dissolve.
In Situ Copper Leaching in the United States: Case Histories of Operations. The copper industry has had a long and interesting history associated with leaching, involving vat, dump, heap, and in situ methods. The Bureau of Mines has also had an interest in copper leaching and has researched the techniques of solution recovery,...

Also called insitu leaching, or ISL, as well as insitu recovery (ISR) and solution mining, this process is usually used to recover minerals such as uranium and copper. This is done through boreholes which are drilled into a deposit, in situ.
The Mopani copper mine in Zambia uses in situ leaching in parallel with conventional underground mining (Steven, 2009). Another operation was conducted by Mercator Minerals at the Mineral Park mine as recently as 2013, but a recent bankruptcy has made the current status of this operation unclear ( Simmerman, 2013 ).
Curis Resources, a Canadian Junior mining company is proposing an insitu copper mine on the banks of the Gila River within the town boundaries of Florence, Arizona. Don Steuter, the Conservation Chair of the Grand Canyon Chapter of the Sierra Club (and one of our steering committee members), wrote an editorial about the proposed project which appeared in the Arizona Republic today.
minerals and pyrite from lowgrade copper ores and mining waste (waste rock, overburden, oxidized portions of the ore body) proceed according to the following stoichiometric equations shown in Table 1 [16]. Dump, heap and insitu leaching are the most common hydrometallurgical methods for
BHP Billiton Closes San Manuel Copper Mine. The development of the open pit mining operations began in 1985. By the 1990s, the operation included an open pit, solvent extractionelectrowinning operation, an insitu leaching process and underground sulfide mine. Prior to being placed on care and maintenance in 1999, the San Manuel Mine produced a world record 703 million tons of ore hoisted.
Insitu recovery seeks to remove mineral ore from right where it sits, as opposed to removing large amounts of rock and earth above and around it. Insitu recovery is commonly used to recover copper and uranium. Insitu recovery, or ISR, is an extraction process designed to leave a .
