The vertical Paste Thickener is based on the principle of static decantation and the natural settling of suspended solid particles. During settling the solid particles settle down to the bottom of the structure, while the clarified water overflows into the overflow weir at the top. Underflow density is increased by the addition of flocculant ...
WesTech's HiDensity™ Paste Thickener produces non-settling thickened tailings with lower viscosities and underflow concentrations than what is produced in the Deep Bed™ Paste Thickener. The HiDensity Thickener …

What is Paste? Paste thickening technology is a long-term solution for many challenges facing the minerals industry. Thickening a stream to produce paste (also called "thickened tailings") offers unique advantages: • Increased water recovery • Smaller tailings disposal volumes • Maximum product recovery from a thickener
Key to the more widespread use of paste technology, whatever the reason for its application, has been the development of the deep-cone (or deep-bed) type of thickener. As Fred brunn from the U.S. operations of FL noted in a keynote presentation at the Paste 2011 conference earlier this year, John Dorr patented the thickener concept ...
The new paste thickener provides ease of operation and reliability for applications requiring a high degree of dewatering, such as minerals tailings, mine backfill, and pre-leach and CCD circuits. The technology is customized to address each operation's unique drivers, which can include environmental concerns, water recovery, regulatory ...
The workhorses behind this technology is the paste thickener. The increased underflow solids content that a paste thickener can achieve can create real benefits for several applications, including the counter current decantation (CCD) circuit, mine backfill, autoclave feed and surface tailings disposal impoundments.
Paste thickeners themselves are well proven and work on a wide variety of PSDs, from red muds to mineral sands, in hundreds of installations.. There is generally a lower limit of …
Outotec improves paste thickening technology Finnish mineral-processing tech company Outotec has made mechanical and process control improvements to its paste …
Paste thickener technology entered the Indian iron market in 2015 when the Shri Bajrang Power and Ispat Ltd (SBP&IL) plant installed a 14 m diameter WesTech Deep Bed TM thickener. This site provides a good study for paste thickener use to address some of the iron slimes and TSF issues. This site has a small TSF footprint.
Paste Thickeners can help producers eliminate the need for settling ponds and other structures. They are also able to eliminate freestanding water or ponds. Not only does this create a safer working environment, it also helps …
The application of paste thickening technology outside of alumina is relatively new. Interest and installations in paste thickening are rapidly growing. ... The paste thickeners at the DeBeers CTP plant in Kimberley, South Africa are the latest example of paste tailings disposal on the surface, also called "stacking". Houman (2003) The use ...
Development of Paste Thickening Technology. Thickeners were invented in the early 1900s, though batch settling tanks go back much further. John Dorr patented the continuous thickener in 1906, which included a circular tank and a set of rakes. Starches and guar were used as coagulants to agglomerate the solids and improve settling rate and ...
years, this thickening technology has evolved and refined to consistently produce non-settling, non-segregating underflow. The improved underflow density can be in the range of 10 – 15 percentage points higher than underflow from a high-rate thickener. The WesTech Deep BedTM paste thickener is the latest advancement

The successful implementation of filtered, paste and thickened tailings technology is dependent on a sound understanding of slurry colloidal behavior, thickening and thickener operation, filtration, rheology, pump and pipeline …
Over the years, this thickening technology has evolved to produce a non-settling solids suspension with underflow concentrations much higher than what is produced with conventional or high rate thickeners. Amstar's Deep Bed™ Paste Thickener is the latest advancement in the evolution of this style of thickener. The Amstar Deep Bed Paste ...
Typical paste thickeners drives have 8-10 times the torque compared with the same diameter high rate thickener. In addition, paste thickeners need to have much longer mud retention times in order to thicken to higher densities. That makes the tanks much deeper, again adding cost, but also an area where it's possible to skimp and under-design.
