Insitu recovery is commonly used to recover copper and uranium. Insitu recovery, or ISR, is an extraction process designed to leave a mines physical location undisturbed. It is touted as an environmentally cleaner method of extraction.

In situ leaching of copper: Challenges and future

In situ leaching offers a potentially attractive way to extract copper from the subsurface without costly fragmentation and processing. Applicability of in situ leaching is limited to deposits where sufficient permeability exists and where the copper and gangue mineralogy is amenable to leaching.

Valuation of a mining company

4 thoughts onValuation of a mining companyRahul Pratap Singh November 10, 2011. Interesting insight. I was under the impression that the DCF was solely based on the CashFlows for a particular year and was independent of the stage the company was in.

Copper extractionWikipedia

Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

TENORM: Copper Mining and Production WastesUS EPA

TENORM: Copper Mining and Production Wastes .There are two main leaching methods: heap leaching and insitu leaching. Heap leaching is the most common method used in the U.S.This liquid contains the dissolved copper, known as a pregnant leach solution PLS. The copper present in this liquid is collected and later processed.

Radiation ProtectionUS EPA

The bioleaching of sulphide minerals with emphasis on

The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides .Chalcocite Cu 2 S is the main copper sulphide mineral mined at bioleaching operations. Some of the chalcocite heap operations began as oxide chemical leach operations and were converted to bioleach oxidative operations by heap aeration and/or inoculation,

PeroxyChem: Klozur® SP For In Situ Chemical Oxidation

Klozur® SP is the oxidant of choice for in situ chemical oxidation ISCO, because of its ability to treat a wide range of contaminants including chlorinated solvents, petroleum hydrocarbons and PAHs. When properly activated, Klozur SP provides an unmatched combination of oxidative power and control that can be delivered both safely and cost effectively.

An Overview of Use of LinzDonawitz LD Steel Slag in

Physical and chemical and mineralogical characteristics of LD steel slag. It has been found that the density of LD slag lies between 3.33.6g/cm. 3 Due to its high Fe content, steel slag looks in appearance a loose collection, and appears hard and wear resistant. The grindability index of steel slag is 0.7, in contrast with the value of 0.96 and 1.0 for blast furnae slag and standard sand

Amino acids key to new gold leaching process

Curtin University scientists have developed a gold and copper extraction process using an amino acidhydrogen peroxide system, which could provide an environmentally friendly and cheaper

World Uranium MiningWorld Nuclear Association

Much of the world's uranium is from Canada, Australia and Kazakhstan. Uranium production is increasingly by in situ leaching. Output of uranium has generally risen in recent years.

Insitu leaching recovery of copper: whats next

This paper highlights some historical aspects of copper in situ leaching, and also reviews some commercial and experimental projects involving both oxide and sulfide deposits. In addition, large wholecore leaching experiments using a copper oxide ore will be described.

Heavy Metals in Contaminated Soils: A Review of Sources

5.1. Immobilization Techniques. Ex situ and in situ immobilization techniques are practical approaches to remediation of metalcontaminated soils. The ex situ technique is applied in areas where highly contaminated soil must be removed from its place of origin, and its storage is connected with a high ecological risk e.g., in the case of radio nuclides.

Atmospheric acid leaching of nickel laterites review: Part

A number of key studies have considered the association of nickel with the various minerals in lateritic ores although various leaching studies described later provide evidence for the deportment of nickel.

Recovery of Copper by Solution Mining MethodsAZ

Copper as well as a number of other commodities are harvested by solution mining methods. Watersoluble salts such as potash sylvite, rock salt halite, thenardite sodium sulfate and nahcolite sodium bicarbonate are commonly derived from massive sedimentary deposits by insitu methods.

In situ leachWikipedia

Heap leachingWikipedia

Heap leaching.Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Most mining companies, favor the economic feasibility of the heap leaching,

In

Insitu copper leaching is a proven technology.In the case of copper, the solution used is a weak sulphuric acid similar to that used for typical heap leaching of copper oxides. The pregnant leach solution is then processed at an Solvent ExtractionElectrowinning plant.
