Weir Minerals has successfully partnered with a number of customers around the world to make this happen. "There are mulঞple ways in which we can help our customers reclaim water from their tailings and re-use it throughout the mine site. From pump house systems to innovaঞve and customised barge soluঞons, we find a soluঞon that is right for the customer. These opঞons can be complex, and we work with the customer to educate them on how the systems work and showcase the benefits, it's a collaboraঞve approach," says Mr Ross. Operators usually rely on mulঞple OEMs for dewatering projects, which is a labour intensive task dealing with different providers and ensuring a soluঞon comes together in a streamlined process. Weir Minerals can remove this headache by project managing the enঞre dewatering soluঞon, uঞlising products from its extensive dewatering range. This involves a thorough assessment of the requirements of the site, including the mine plan, operaঞng depths, and exisঞng infrastructure, as well as required water in-flow. "We provide a resilient process against the backdrop of increasingly difficult condiঞons in which many of our customers operate. What we deliver is an opঞmal dewatering plan, backed up by recommendaঞon for regular equipment maintenance to keep unscheduled stoppages to a minimum," Mr Ross concludes. Weir Mine rals use experঞse in both process and products to maximise efficiency and help operators take control of their water. Visit www.dewateringsoluঞons.weir for more informaঞon. Over the next decade, many mines across the globe face closure making it an increasing priority for the industry, government and communiঞes. The social and economic benefits of closing a mine are usually significant and underline the importance of early preparaঞon. Recognising this, the Internaঞonal Council on Mining and Metals (ICMM) published an update to its Integrated Mine Closure: Good Pracce Guide. The guide is available to mining companies and regulators, and contains a range of tools that can assist in making well- considered decisions when planning for and closing a mine. This guide presents an updated version of ICMM's 2008 Planning for integrated mine closure: toolkit. Like the earlier version, guidance is provided on criঞcal aspects of mine closure focused on an iteraঞve process, from the earliest stages of knowledge gathering, engagement and planning. The updated guide provides emphasis on the importance of social transiঞoning, progressive closure and strategies for relinquishment and closure governance. The guide also includes tools at the back of the document to help support planning for closure. "Integrated mine closure is a dynamic and iteraঞve process that takes into account environmental, social and economic consideraঞons at an early stage of mine development," said ICMM in a statement. "Fundamental to this process is the need to consider closure as an integral part of the mine operaঞons' core business." The structure of this guide reflects this process, providing good pracঞce guidance in delivering key elements of mine closure planning and implementaঞon, and early definiঞon of the closure vision. According to ICMM, the document is not intended to be prescripঞve. Rather, it serves as a toolkit that can be uঞlised in formulaঞng well-considered decisions when planning and execuঞng closure. "It uses a risk and opportunity-based process to guide the pracঞঞoner through the iteraঞve process of planning for final and progressive closure in a considered manner, as well as tacঞcs for considering sudden or temporary closure," states ICMM. As experience has shown, a balanced closure approach fully incorporated int mine planning acঞviঞes will lead to beer outcomes across a range of consideraঞon including health, safety, social, environmental, legal, governance and human resources.
