Mobile dry stack tails system at the Karara Mine Site in Australia. The need for sustainable tailings management. One effective way to increase water recovery is to look at a more sustainable solution for a plants tailings management requirements. The processes used in mineral extraction produce enormous volumes of waste, known as wet tailings.
increases. The different deposition time of tailings dam and the physical and mechanical characteristics of tailings in the sedimentary area are quite different, especially for high stacked tailings dam. Therefore, it is very important to study the variation of physical and mechanical characteristics in the tailings of high stacked tailings.
So, it recommended an alternative method of filtering the water out of the tailings and then stacking them in a big pile, a method commonly called dry stacking.
Some large mining operations produce over 100,000 dry tonnes of tailings per day. Dewatering this massive amount of solids to the geotechnical requirements needed for dry stacking requires large filtration areas using old technology, this would require football fields of filters, all of which would need the associated piping, valves, pumping and conveyances.
The fresh tailings come to the plant through a 40 kilometre tailings launder from the El Teniente mine, while the older Colihues tailings are pumped in from the pond.

Innovative tailings solutions high density thickened tailings (paste), dry stacking . Exploring innovative tailings storage solutions is one way to potentially reduce operational costs and significantly. Commodity prices are still low and the need to reduce operation costs is still high. The opportunity to utilise innovative techniques to
High Recovery Rate Scheelite Production Line,Copper Flotation Line,Copper Scheelite dressing can use gravity, magnetic and flotation separation. energy saving tailings dry stacking
Outotec Dry Tailings Plant product consist of thickening, filtering and dry material handling processes. A Thickener Plant will dewater the tailings from very low solids density to medium and high density.
Tailings Re Processing Gold CIP Production Line adsorbs gold from cyaniding pulp by active carbon including 7 steps leaching pulp preparation, cyaniding leaching, carbon adsorption, gold loaded carbon desorption, pregnant solution electrodeposit, carbon acid regeneration, leaching pulp.
Surface stacking is the disposal of tailings on the surface of the ground. As a non settling, non segregating suspension of solids, minimal water is released into the impoundment and the stacked tailings dries significantly faster than conventional ponds where fines (slimes) segregate and can seal the surface of the deposit, preventing drying.

(The density of molybdenum is about half that of tungsten so it only takes 1% molybdenum to equal roughly 2% tungsten) , (such as molybdenum, copper, etc) float to the surface of the flotation cells when nitrogen is injected allowing separation of the valuable minerals from the tailings (non valuable) minerals This first step is known as bulk
Dry stacking is suited to areas of high seismic activity as the construction of retention embankments is prevented. For cold climates, dry stacking prevents pipe
Tailings . Dry stacking. Tailings do not have to be stored in ponds or sent as slurries into oceans, rivers or streams. There is a growing use of the practice of dewatering tailings using vacuum or pressure filters so the tailings can then be stacked. Get Price Treatment of copper mine tailings using a
Filtered tailings (dry stacking) style of tailings storage is becoming more popular mainly due to the growing need to reduce makeup water costs in the mining industry. Over the recent years there has been a significant advancement in the field of dewatering of tailings
Storing tailings underground is another alternative for underground mines. Dry stacking is an alternative that may not always be a viable option in B.C. due to its high levels of precipitation.
The Outotec Dry Tailings Plant is a fully integrated design that comprises thickening, filtration, and dry material handling for tailings dry stacking, including all necessary ancillary equipment and systems.
Caren Tailings Dam. Codelco El Teniente (Alhue, Metropolitan Area, Central Chile) Chile should be one of the best places to apply the most up to date methods of dewatering technologies like thickened paste tailings, filter tailings and dry stacking disposal. However, applying these methods hasnt been very successful for the new projects.
Figure 3 Dry stacking of tailings using truck transportation (169; Jon Engels) Some of the disadvantages to dry stack tailings are as follows High capital and operating costs associated with modern filtration technology (power, maintenance) that render other tailings storage options more economic to develop.
Offshore discharge, dry stacking, reburial, cementing, and in pit disposal are among the other options available. Dry Stack Removing most of the water from tailings allows them to be stored in piles, rather than as a mud slurry.
The type of paste thickener underflow generally used for surface stacking of tailings is called thickened tailings. Thickened tailings are a suspension of solids which are relatively non settling and non segregating and which have a higher concentration and viscosity than that of conventional tailings.

Except the method of stockpiling in tailings pool, dry tailing stacking and mine filling, Xinhai will also apply gravity separation, flotation separation, magnetic separation, gravity flotation separation, and other process to recycle the valuable elements.
It is the first domestic company who developing tailing dry stacking technology and equipment. In 2009, Xinhai started developing the third generation tailing dry stacking technology and equipment hydro cyclone, high efficiency thickener and high efficiency multi frequency dewatering screen.
Award of Excellence Tailings Management at Greens Creek Mine. The Hecla Greens Creek Mining Companys polymetallic mine (silver, gold, zinc and lead) is located on northern Admiralty Island in Alaska. A portion of the mine facilities located within Admiralty Island National Monument.
Expensive positive displacement pumps (CAPEX y OPEX) are usually required for paste tailings discharge (some manufacturers having high lead times). However, centrifugal pumps can pump paste depending on the rheological properties of tailings (principally the yield stress). High operating costs associated with the thickening and transportation of paste compared to other methods (even filtration).
The issue of sustainable water management is thus becoming increasingly important to global mining operations, especially in areas where water conservation is critical, and the employment of dry stack tailings management systems is a tangible approach to sustainable water management.
Tailing dry stacking is a new tailing treatment technology. In the dry stacking method, filters and vacuum presses remove more of the water, which can be recycled
It is the needed piece of the puzzle towards the only sustainable tailings management dry stacked tailings which maximises the water recirculated in the process, states Todd Wisdom, director of tailings solutions at FL. The increasing challenge of water. Tailings can make up as much as 98% of the total ore mined.
