Last month, CSIRO held its inaugural Resources Innovation Showcase that focused on the future of mining and innovations that can reshape the way mines operate. As part of the day, my colleague, Dr Laura Kuhar, presented on in situ recovery (ISR), a topic that is growing in interest around the globe.

Sep 18, 2015 The uranium industry wants to bring in-situ leaching uranium mining to New Mexico, putting precious water resources in danger.

In-Situ Leach Mining The Next Quantum Leap? By S. HANCOCK' Chairman - Principal Consultant Australian Groundwater Consultants Pty. Ltd. 6/456 High Street, Prahran, Victoria Australia, 3181 ABSTRACT This paper considers the opportunities and problems which in-situ leach mining technology presents to the mining industry. Ablative Arc Mining for In-Situ Resource Utilization In-situ Leaching – In-situ Recovery. As with other types of hard rock mining there are several methods of extraction. In case of uranium mining, it strongly depends on the concentration of uranium in the ore.

In situ mining means a method of in‑place surface mining in which limited quantities of overburden are disturbed to install a conduit or well and the mineral is mined by injecting or recovering a liquid, solid, sludge or gas that causes the leaching, dissolution, gasification, liquefaction or extraction of the mineral. In-situ is a Latin word that literally means “in the place.”. Unlike conventional mining methods, in situ recovery (ISR) removes the ore while leaving the rock “in the place.”. ISR utilizes a series of EPA Class III wells to inject native groundwater, fortified with oxygen and baking soda into the ore zone.

The submersible pumps initially extract native groundwater from the host aquifer prior to the addition Remote ion exchange.

Mining In Situ 132 grams/barrel 146 grams/barrel Mining In Situ 132 grams/barrel 146 grams/barrel In the case of in-situ leaching (ISL) - also called in-situ recovery (ISR), or solution mining - the uranium-bearing ore is not removed from its geological deposit, but a leaching liquid is injected through wells into the ore deposit, and the uranium-bearing liquid is pumped to the surface from other wells. In mining, you must find a deposit that is large enough to justify the capital-intensive investment that is open-pit or underground mining.

2018-9-17 · The main difference between in situ and ex situ is that the in situ refers to the original location whereas the ex situ refers to the off-site.Furthermore, in situ methods are less expensive and less manageable while the ex situ methods are expensive and manageable. In situ and ex situ are two methods used to describe different biological processes such as bioremediation, and conservation of

situ stress fields in which the mining excavations are created. From the point of view of planning of mining operations, the in situ stress field is a most important input parameter for valid modelling of excavations. Many in situ stress measurements have been carried out for mining and civil engineering projects in southern Africa over the Mining is the process of digging into the earth to extract naturally occurring minerals. It can be categorized as : surface mining, underground mining, and in situ mining.
