Xinhai tailings re-processing line, with the thought of protecting ecosystem and fully using resources, provide a re-processing for those valuable metal or non-metal tailings. According different property of all kinds of ore tailings, Xinhai can design reasonable process and fully find the value in the tailings.
The EXAMPLE Gold Mine Operating Manual has been prepared to provide a practical reference for operators in the EXAMPLE Gold Mines Processing Plant. This manual contains basic information about the process and equipment used in the process. Each unit is identified by name and equipment number. The function of each unit, a process

Las Lagunas Gold Tailings is a retreatment project involving the reprocessing of previously unrecovered gold and silver refractory tailings from the Pueblo Viejo mine.
Historically, poor recovery rates in mining have left significant amounts of recoverable material in tailings. This can be extracted with dredges. Blogs posted by Ellicott Dredges, which sells dredgers for sand mining, harbor maintenance, river and channel dredging, and environmental clean-ups.
Holistic tailings management solutions Careful planning of the Tailings Storage Facility (TSF) and the treatment of the waste streams is required long before operations begin, throughout the mine life and for long term sustainable remediation after closure (cradle to grave). As
responsible for treatment and processing of the tailings and recovery of gold thereafter and will receive associated income from the gold produced, net of associated costs and purchase price of the tailings. Gold bearing waste tailings are materials which remain from old gold mining operations and may pose a threat to the environment and health

Watson Department of Chemical Engineering University of Arkansas Fayetteville, AR 72701 EXECUTIVE SUMMARY A process was designed to recover a pile of 50-year-old mine tailings
Gold Tailings: Hazards and Opportunities Investing News Network - October 4th, 2015 Tailings from gold mining operations can pose a threat to the environment and health of nearby communities. Not only can this waste be harmful if it leaches into groundwater, but it can also mean losing minerals still contained in the residue.
The utilisation of iron ore tailings as aggregates in concrete could have positive environmental implications to the mining companies and the mining communities and will provide cheaper alternative materials to bring about economy in concrete production.
Following pressure from advocates, Citigroup said last month that it will not fund any future mining projects over $50 million that dispose of mine waste in the oceans. Tailings, a fine-grained, often toxic slurry left over after the processing of mined ore, are still disposed of in oceans, lakes
Mining companies are making significant investments to improve the efficiency and safety of their tailings management processes, driven by issues such as increasing water scarcity, environmental pressures and legislation, and the need to maintain profitability. New technologies and design strategies are needed to address these challenges.
Outotec introduces three new products for sustainable tailings and water management in minerals processing As ore compositions at mines around the world become more complex and the grades of available resources continue to decline, the amount of tailings per ton of metal produced is rising. Tailings management is a
