Thickeners: How they Operate Mainland Machinery

Thickeners: How they Operate. The most common solidsliquid S/L unit operation is thickening. A wide variety of thickeners are used including conventional, deep well, paste, high rate and clarifiers which is a thickener subclass used for removing solids from turbid or very low solids waters.

Thickeners Types, Working Principle and Appli ions by

Historically, thickeners were introduced to the mining industry in 1905. They are widely used in various industries including mining, coal, chemical, industrial, environmental wastewater

How a Thickener Works

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flatbottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were

Thickeners or thickener plantsoptimizing the performance

Advances in thickener design have improved the degree of separation possible from tailings streams, however limiting the selection criteria to just the thickener can constrain the operation potential. Integrating ancillaries, automation and operator training with the equipment can improve operational outcomes and decrease operating costs.

HighRate Thickeners are used by the aggregate and mining industries, as well as environmental contractors, to recover approximately 85 of water for reuse. This highlevel of water recovery keeps water consumption at sustainable levels, as well as drastically reduces the slurry volume reporting to waste ponds.

Maximize Precious Metals Recovery with CCD Circuits and High

A less obvious benefit to choosing thickeners capable of producing nonNewtonian underflow is a substantial reduction in footprint. In the graphic above, the red circles represent deep cone thickeners, green represents highdensity, and blue is highrate. Footprint can become a significant CAPEX consideration when excavation costs are elevated.

UltraDense Thickeners from McLanahan Aggregates and Mining

McLanahans HighRate and HighDensity Thickeners are simple in design and operation, but offer a multitude of benefits for producers. Although both sized based on hindered settling velocity, HighRate Thickeners feature lower side walls and lower sludge densities, while HighDensity Thickeners have higher side walls and denser underflows.

Paste thickening optimizes tailings disposal and water

These thickeners recover approximately 90 percent of the slurry water by volume. Most mining facilities would then deposit the tailings slurry direct into a tailings pond at about 40 percent to 50 percent solids. But this highrate primary thickener was inadequate to produce slurry densities required for the desired water reclamation.

Actually, thickeners simply concentrate the solids, achieving underflow solids densities from 20 solids to 50 solids. Typical thickener feeds range from 2 solids to 10 solids by weight . Feed enters the thickener near the center, below the water level. Gravitational acceleration causes the solids to fall towards the bottom of the thickener.
