Tailing ponds are a recognizable phenomenon in the mining landscape. Remediation or re-mining of tailings becomes more important nowadays, pushed by either an economic driver or a an environmental driver, or from both. Historic poor recoveries during processing may have resulted in tailings that still contain significant amounts of recoverable metals. Tailings can also contain metal products that were earlier non-profitable to process further and hence seen as a waste product. These metal products in tailings may be of much more value today due to profitable extraction with modern processing techniques and current commodity prices . Another important reason to remediate tailings is to mitigate any threats and to prevent potential damage to the environment. Different techniques can be used for tailings remediation. The optimal technique depends on the project conditions and the tailings deposit characteristics. Hydro guns (or monitoring guns) are generally a good technique for tailings heaps. Tailings are loosened by jetting, transported via launders and collected in a sump at the toe of the heap. In case of tailings dams, ponds and beaches, the tailings are likely to be present in a watery environment, making dredging a good solution. A dredger excavates and slurrifies the material and pumps it straight to a processing plant in order to reprocess the material. Since tailings are already processed at an earlier stage, loosening of tailings during remediation is an easy operation In case of “heavy” materials (e.g. iron), the hydro gun application becomes more challenging due to the deposition of material in the launders. In dredge mining, excavation, slurrification and collection (suction) of tailings occurs simultaneously, making dredging a suitable solution, with wide applications in tailings remediation projects. Different case studies in Chile and Brazil are discussed in this article to illustrate this. ]]>

IHC Mining Advisory Services (IMAS) recognises the importance of clear and sound advice during the development of any mining project. Its aim is to support customers in realising the true potential value of their wet-mining operation by providing efficient solutions throughout the life cycle of the project. With an extensive track record, IMAS is able to provide advisory services throughout the entire mining operation. These are tailored to the exploration and mining of specific commodities, including: • heavy mineral sands • gold • tin • diamonds • iron sands]]>

0 https://cdn.slidesharecdn.com/profile-photo-BartHogeweg-48x48.jpg?cb=1523387787 Bart Hogeweg is a mining engineer by background, earning his MSc from the Delft Univeristy of Technology in 2008. Bart joined Royal IHC in 2007, doing his MSc thesis study at MTI Holland, IHC’s research and development unit. Following his successful thesis project, Bart started as mining consultant at MTI Holland providing clients with advice on the application of dredging technology in their mining projects. Projects all over the world extended Bart’s already broad mining experience, which he gained during multiple internships and international education programs at university. To push his personal development in a commercial and corporate direction, Bart took to opportunity to join https://cdn.slidesharecdn.com/ss_thumbnails/infoflyerdutcheventsminingindaba2016-160128132418-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/info-flyer-dutch-events-mining-indaba-2016/57604640 Info flyer Dutch event... https://cdn.slidesharecdn.com/ss_thumbnails/30924861-224d-4430-a3e9-d3f99726564e-151117120604-lva1-app6891-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/imas-flyer-2015/55202402 IMAS flyer 2015 https://cdn.slidesharecdn.com/ss_thumbnails/20150822-presentationtailingsconference2015lrweb-150824185854-lva1-app6891-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/tailings-remediation-with-dredge-mining-technology/52017098 Tailings remediation w...
