Jun 25, 2019 · Today''s infographic from Excelsior Mining Corp. outlines a unique mining method, InSitu Recovery "ISR", also known as InSitu Mining. An Intro to InSitu Mining. ISR is not a recent innovation in the mining sector. In fact, ISR has been used for the past 50 years in uranium mining, and 48% of the world''s uranium gets mined this way.
Manage all water inflow, storage and discharge at your mine site, and have confidence in your site assessments, dewatering and mine reclamation activities, with continuous monitoring equipment for mine water management that delivers data you can trust.
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.
10 Top Copperproducing Companies. Chilean coppermining company Antofagasta produced 370,000 tonnes of copper in 2016, a decrease from 2015''s total of 370,000 tonnes.
Insitu Copper Mining: Another type of mining being tried by BHP at Florence, AZ is insitu copper mining. A weak acid solution is injected in wells to dissolve the copper in the ore without removing it. The concentrated copper solution is then pumped out of recovery wells.
Terms such as in situ mining, in situ leaching, solution mining, borehole mining, and slurry mining have been used in different ways to describe a wide range of mining operations where a commodity is usually extracted remotely by activities that are conducted from the surface.
In situ leaching (ISL), solution mining, or in situ recovery (ISR) involves dissolving uranium in the ground and pumping the solution to the surface where the minerals can be recovered. Information from the World Nuclear Association, the global privatesector organization that provides information on nuclear power, nuclear energy, and the role of nuclear in sustainable development.
Beginning in 2020 and spanning a 24year mine life, Gunnison Copper is projected to produce more than twobillion pounds of copper and add more US$2.94 billion to Arizona''s Gross State Product, while operating with little to no noise, dust or emissions. Learn the facts about insitu copper recovery. Learn the facts about Today''s Green Mining.
Gunnison Copper ISR InSitu Copper Recovery. Insitu means "in the natural or original position." In the simplest terms, insitu recovery (ISR) involves removing the selected minerals or metals without digging up the host rock.
From 1981, insitu leaching was also used to increase the yield from mined out conventional underground mines [Tabakov1993]. From 1981, 23 ore deposits were mined by conventional underground mining techniques, 17 by in situ leaching from the surface, and 11 by insitu leaching in combination with conventional mining techniques.
Insitu valuation is a fairly straightforward method of valuing miners. In essense it is simply the value of all mineral resources (measured + indied + inferred) that mining company owns.. Of course the value of a company is not simply the value of the resources it owns in their mined and processed state.

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, particularly concentrating on in situ methods.
The mining practice that uses solutions to extract a desired commodity from an ore deposit where it stands without also extracting the rock is known as solution mining. There are essentially two types of solution mining: 1) insitu and 2) inplace.
How Do They Do That? In Situ Mining Copper Appliions in Mining & Extraction. By BHP. Insitu mining is designed to coexist with other land uses, such as agriculture. The insitu mine will typically consist of a series of injection wells (A) and recovery wells (B). The wells are built with acidresistant concrete and a PVC casing.
Copper extraction refers to the methods used to obtain 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.

Insitu methods were used to mine about half the world''s uranium recovered in 2016, but it''s less common on copper deposits. "The challenge with copper is that even the copper that dissolves easily has to be dissolved by an acidic solution," Nelson, the mining professor, said. "Uranium, they can leach that with just an oxygenated water.
