In situ leachingISLis the dissolution and subsequent recovery of minerals from the subsurface by injection of a chemical solution. Because ISL of gold does not involve bulk rock mining, it has great potential to be substantially more environmentally friendly than conventional methods.

Infographic: Everything You Need to Know About In-Situ Mining

Today’s infographic from Excelsior Mining Corp. outlines a unique mining method, In-Situ Recovery “ISR”, also known as In-Situ Mining. An Intro to In-Situ 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.

In-Situ Chemical Oxidation US EPA ARCHIVE DOCUMENT

H2O2and ironFe . In general, Fenton chemistry and in-situ Fenton oxidation is complex, involves numerous reactive intermediates and mechanisms, and technology development has been slower. OzoneO3is a strong oxidant that has been used in the subsurface but in much more limited appli ion than permanganate and Fenton-driven oxidation.

Setting sights on invisible mining - CSIRO

In-situ recovery or ISR, particularly from hard rock ore bodies, is a technology that involves drilling, rock fracturing and leaching of value metals away from gangue while the rock remains in place. It has the potential to be a game changer for deep and sub-economic deposits, and provide an alternative to open cut and underground mining.

IN-SITU RECOVERY OF COPPER COMES OF AGE

Copper in-place leaching has a long history. Since the 1950 60s it has been applied to low- -grade . oxide and sulphide ores on flat terrain, on hillsides, and in pre-existing open cut and underground mines, particularly in the USA. The ore was generally broken by blasting and the solution was allowed to percolate down through

Rock Fragmentation by Blasting - Orica

By optimising rock fragmentation by blasting, you can achieve significant improvements in waste productivity, mill throughput, fragmentation profile and wall stability. Stuart Thomson, Orica& 39;s Global Bulk and Packaged Explosives Product Manager, explains in this paper how blasting improves productivity and environmental performance with some ...
