High-rate thickener. ANDRITZ process engineering will determine the optimum percentage of feed solids for the specific application during laboratory or pilot plant test work. The optimum percentage of feed solids will ensure proper flocculation and achievement of maximum fluxes (t/m 2 /d).The results of laboratory evaluation showed that the viscosity of the high-temperature gelled acid at 180 °C was 30 mPas, with a corrosion rate lower than 70 g/m 2 h.The drag reduction and acid-rock reaction rates reached 64%–71% and 1.569 × 10 −4 mol/cm 2 s respectively, demonstrating obvious retarding performance.Research and application of stimulation fluid technology for deep

Figure 7: High rate thickener tests. Below Figure 8 shows laboratory-scale units with a diameter of 190 mm and a height of up to 4 m. It has been established, after numerous comparative lab tests, that with the 190 mm diameter unit, the “wall effects” are negligible, and results equivalent to pilot scale are achieved.

Why thickener and filtration testwork is critical in a FLSmidth
By performing thickener testwork, we determine the optimum feed solids, settling rate, flocculant dose, underflow density and mud residence time to correctly size a thickener for the required duty. The MissionZero testing looks at the implications of treating coarse tailings from the CoarseAir flotation much earlier in the flowsheet, meaning water is recycled 3:33. High-Rate Thickeners separate liquids from solids using hindered settling. Rotating rake arms collect settled sludge and move it toward the center discharge cone. They use minimal amounts of polymers/chemicals to drop the solids, making High-Rate Thickeners environmentally friendly. Thickeners are operated and controlled by a touch-screenMcLanahan High-Rate Thickeners

The “Thickened Tailings Disposal” (TTD) technology produces a high density mine waste that allows for the storage of this material without the need to manage large slurry tailings storage facilities (TSFs) and large dams. TTD has been applied considering site specific conditions of Chile and Peru, such as extreme climatic Thickener outputs can accommodate a range of tailings disposal options from low yield stress, Figure 2 is an example of laboratory data from a simple batch settling test in the presence of raking. 100 have been observed for selected materials in high rate thickeners.

Effect of settling test procedure on sizing thickeners
There are several thickener design methods applied in the mining industry including Coe-Clevenger (Coe, 1916) or Talmage-Fitch (Talmage and Fitch, 1955) approaches. Besides easy-to-determineWesTech HiFlo™ high-rate thickeners are used in many types of process circuits to separate liquids and solids at very high rates.

High-Rate Thickener. Watch to learn how McLanahan High-Rate Thickeners can help to reduce settling ponds or tailings storage facilities. Thickeners meet the customer's needs and operate successfully, samples of the customer's material are tested in their laboratory.Our response was to engineer and build a thickener that will achieve underflow densities at the limits between high rate and high density. It features a floor slope that is typically used in high-density thickeners (3:12), which gives it a depth of almost 20m in the centre.Thickener evolution a testament to customer commitment
