6 Advantages of Efficient Improved Thickener. The thickener is one of the indispensable equipment of each large-scale beneficiation plant, which is suitable for the dewatering treatment of concentrate and tailings in the beneficiation plant.However, with the continuous improvement of mineral processing requirements, the disadvantages of traditional thickeners are becoming more and more

Filtration and thickening are areas of mineral recovery technology that are often overlooked. Nonetheless, they represent an important component of the entire process, since without dewatering, it would be hard to produce concentrates to transport specifications while water recycling from tailings streams is becoming increasingly important as energy costs for pumping steadily increase

The advantages of paste thickeners in tailings circuits have been well-established for most minerals. 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

Paste thickeners thicken tailings to higher underflow solids concentrations than conventional and high-rate thickeners. For example, a tailings stream in an iron ore application could be thickened to 45–50% solids Newtonian slurry in conventional or high-rate thickeners. Conversely, the same tailings stream could be thickened to 65–70% solids non-Newtonian suspension using a paste thickener

Increased water recovery is important to many countries throughout the world due to the scarcity of fresh water. The more water that can be recovered from a tailing stream and, in turn, used again upstream in the plant reduces the amount of fresh water a mine needs. The cost of water is frequently one of the primary drivers for implementing a thickened or paste tailings disposal system

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

Stacking as a method of tailings disposal offers significant advantages over ponding. These advantages include: smaller impoundment area, less water in the pond, improved water or chemical recovery, a lower risk of containment breach, less groundwater contamination, and easier final reclamation of the site

When tailings ponds reach their capacities, the construction of a new dam is usually the solution for the deposition problem. This solution is very expensive and is not always an option if there are environmental, licensing and space constraints

dewatering: an increasingly important mineral process | e & mj

Filtration and thickening are areas of mineral recovery technology that are often overlooked. Nonetheless, they represent an important component of the entire process, since without dewatering, it would be hard to produce concentrates to transport specifications while water recycling from tailings streams is becoming increasingly important as energy costs for pumping steadily increase. In addition, the benefits of dry tailings disposal are becoming increasingly appreciated from both environmental and social responsibility perspectives

This review looks at some of the major players in the supply of both filtration and thickener equipment, companies that over the years have developed and improved upon the technologies and concepts involved. As with other areas of mineral processing technology, efficiency improvements are always the goal, with the aim of optimizing the balance between residual moisture contents and the benefits to be won from water recovery

The Benefits of a Joined-up ApproachU.S.-based McLanahan Corp. has recently been doing a lot of work installing its deep-cone thickeners and filter presses together for several different mineral-processing customers. McLanahan’s director of process engineering for mineral processing, Scott O’Brien, explained the rationale for using this approach to dewatering

O’Brien said while using a thickener on its own will enable an operator to recover 80%-90% of the water in a slurry, the underflow will still contain enough water to make it difficult to handle. Normally, he said, this would go to a pond for further consolidation of the solids, and perhaps to recover some reusable water

“The thickener underflow can go through a filter press to become a cake that can be picked up with a loader and transported. Since filter-press cakes contain such a high proportion of solids, they also stop water dripping all over the road during transport, which officials don’t take kindly to.”

O’Brien went on to point out that producers who do not have a thickener, but do have a filter press, end up putting a dilute feed into the press. This greatly increases the cycle times because more water is going through the press. In addition, he said, longer cycle times of high-velocity water can cause faster wear on the filter cloths
