In Situ Leach (ISL) Mining of Uranium
In Situ Leach (ISL) Mining of Uranium (June 2009) l Most uranium mining in the USA and Kazakhstan is now by in situ leach methods, also known as in situ recovery (ISR). l In USA ISL is seen as the most cost effective and environmentally acceptable method of mining, and Australian experience supports this. l Australia's first ISL uranium mine is Beverley, which started operation late in 2000. The proposal for Honeymoon has government approval and it is expected to be operating in 2008. Conventional mining involves removing mineralised rock (ore) from the ground, breaking it up and treating it to remove the minerals being sought. In situ leaching (ISL), also known as solution mining, or in situ recovery (ISR) in North America, involves leaving the ore where it is in the ground, and recovering the minerals from it by dissolving them and pumping the pregnant solution to the surface where the minerals can be recovered. Consequently there is little surface disturbance and no tailings or waste rock generated. However, the orebody needs to be permeable to the liquids used, and located so that they do not contaminate ground water away from the orebody. Uranium ISL uses the native groundwater in the orebody which is fortified with a complexing agent and in most cases an oxidant. It is then pumped through the underground orebody to recover the minerals in it by leaching. Once the pregnant solution is returned to the surface, the uranium is recovered in much the same way as in any other uranium plant (mill). In Australian ISL mines (Beverley and the soon to be opened Honeymoon Mine) the oxidant used is hydrogen peroxide and the complexing agent sulfuric acid. -

Copper remained the A key feature of the Government of Chile’s development country’s most important export product and accounted for strategy was a welcoming attitude towards foreign investors, about 37.7% of export earnings in 1999. Chile was also one of which was embodied in the country’s foreign investment law the world’s significant producers and exporters of potassium known as Decree Law (DL) 600. DL 600 was promulgated in nitrate and sodium nitrate and ranked second after Japan in 1974 and has been made more liberal through frequent world production of iodine.

Understanding Fluid–Rock Interactions and Lixiviant/Oxidant Behaviour for the In-Situ Recovery of Metals from Deep Ore Bodies
School of Earth and Planetary Science Department of Applied Geology Understanding Fluid–Rock Interactions and Lixiviant/Oxidant Behaviour for the In-situ Recovery of Metals from Deep Ore Bodies Tania Marcela Hidalgo Rosero This thesis is presented for the degree of Doctor of Philosophy of Curtin University February 2020 1 Declaration __________________________________________________________________________ Declaration To the best of my knowledge and belief, I declare that this work of thesis contains no material published by any other person, except where due acknowledgements have been made. This thesis contains no material which has been accepted for the award of any other degree or diploma in any university. Tania Marcela Hidalgo Rosero Date: 28/01/2020 2 Abstract __________________________________________________________________________ Abstract In-situ recovery (ISR) processing has been recognised as a possible alternative to open- pit mining, especially for low-grade resources. In ISR, the fluid–rock interaction between the target ore and the lixiviant results in valuable- (and gangue-) metal dissolution. This interaction is achieved by the injection and recovery of fluid by means of strategically positioned wells. Although the application of ISR has become more common (ISR remains the preferential processing technique for uranium and has been applied in pilot programs for treating oxide zones in copper deposits), its application to hard-rock refractory and low-grade copper-sulfide deposits is still under development. This research is focused on the possible application of ISR to primary copper sulfides usually found as deep ores. Lixiviant/oxidant selection is an important aspect to consider during planning and operation in the ISR of copper-sulfide ores. -

Outotec Casestudy
OUTOTEC’S FEEDGUARD PRODUCT APPLIES ROCSOLE’S TOMOGRAPHIC PLATFORM OUTOTEC FEEDGUARD OUTOTEC FEEDGUARD, BASED ON THE ELECTRICAL CAPACITANCE TOMOGRAPHY (ECT) IS CAPABLE OF DETECTING EVEN THE SMALLEST VARIATIONS IN THE FEED MIXTURE. OUTOTEC FEEDGUARD The Outotec® FeedGuard provides easy and quick detection of uneven feed or feed blockages. It has low maintenance requirements (non-intrusive sensors) and it is based on a very accurate and reliable ECT measurement. An online measurement of feed distribution and ensuring that it is even and without blockages improves the oxygen efficiency of the process, decreases weak acid production and reduces the slag losses of Cu or Ni. The total mass flow of FeedGuard is very close to the total mass flow of the individual feeds, normally within 1 % error calculated over a fill cycle of the loss-in-weight feeder. THE FEEDGUARD SENSOR SPECIALLY DEVELOPED FOR THE FLASH SMELTING OR FLASH CONVERTING PROCESS IT IS INTEGRATED TO THE CONCENTRATE OR MATTE BURNER FEED INLET PORT AND PROVIDES THE MEASUREMENT RESULT TO THE CONTROL ROOM ONLINE ROCSOLE’S TOMOGRAPHIC PLATFORM STATEMENTS PETER BJÖRKLUND TECHNOLOGY MANAGER, OUTOTEC FINLAND OY ”Our aim was to increase the productivity of the concentrate burner and to provide an accurate mass flow measurement. As a base for our product we have been applying Rocsole’s tomographic platform to do the mass flow measurement. A measurement accuracy of 1% has been observed during the pilot project. This FeedGuard solution brings clear benefits to our customers like spotting disturbances and blockages during feeding. In addition to that a non-uniform feed is detected and can be corrected fast.” PASI LAAKKONEN CEO OF ROCSOLE +358 40 147 8797 [email protected] www.rocsole.com “We are glad Outotec has been innovative and applying Rocsole’s Tomographic Platform. -

University of Chile, Santiago De Chile Society of Economic Geologists Student Chapter
UNIVERSITY OF CHILE, SANTIAGO DE CHILE SOCIETY OF ECONOMIC GEOLOGISTS STUDENT CHAPTER Field Trip 2016 – 2017 Santiago de Chile, September 2017 CLARIFICATION NOTE University of Chile, Santiago de Chile SEG Student Chapter clarifies that the initial field application submitted as financial assistance of Steward R. Wallace Fund, Round II, 2015 is different from what is described in this report. The original plan included visits to Minera Los Pelambres (MLP, AMSA), Minera El Soldado (MES, Angloamerican) and División Andina (DA, Codelco). However, it was impossible to get approval for visiting División Andina of Codelco (they request that all the visitors could pass a physical exam to work over 3,000 m above sea level, which costs more than US$100 per person). In addition, the visit to Minera El Soldado was scheduled for November 30, 2016. However, due to contractor workers strike and disturbs in Los Bronces operation during the second half of November, Angloamerican suspended all the visits to their operations in Chile. Therefore, we made relevant changes to the original plan, due to the shortcomings that arose and restructured our visits. We decided to visit the Cerro Negro stratabound Cu deposit, Los Pelambres and El Teniente porphyry Cu-Mo deposits. 1. INTRODUCTION The University of Chile, Santiago de Chile SEG Student Chapter is hosted in the Department of Geology of University of Chile. Activities of the student chapter involve field trips, talks and conferences with the aim of learning about the economic geology, for example, conditions for the formation of mineral deposit, tectonic environments, mineralization characteristics and metallurgical processes.
