Thickening - Resource Book

A thickener has several basic components: a tank to contain the slurry, feed piping and a feed well to allow the feed stream to enter the tank, a rotating rake mechanism to assist in moving the concentrated solids to the withdrawal points, an underflow solids withdrawal system, and an overflow launder.

Slurry Densities - Engineering ToolBox

Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 - c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l …

feed pre-screening the pulp flows through a cascade of well-mixed adsorption tanks, typically 6 to 8 in number. Conventional practice is to have a mean pulp residence time of about an hour in each tank. The tanks are normally mechanically agitated and each will contain a batch of carbon of concentration 10–25 grams of carbon per litre of pulp ...

Difference Between Clarifier and Thickener

The feed well is oversized allowing entrapped air, contained within the feed slurry, to rise and dissipate so it does not enter the main settling zone within the Thickener. Flocculated solids settle to the bottom of the Thickener, compacting in what is known as the compression zone, creating a dense slurry.

Process Engineering | Avoid trouble with slurries ...

Avoid trouble with slurries. ... One very common complaint when feeding batch centrifuges or filters is the variability of the slurry feed particle size. When the feed tank is full, the centrifuge or filter receives mostly large sized particles and the filtration rate is very good. As the tank empties the particle size becomes smaller, the ...

Slurry - Official Mekanism Wiki

Ore Slurry is an intermediate step of Tier 4 Ore Processing.. The Chemical Dissolution Chamber turns raw ores into the corresponding Slurry.. The Slurry is washed by the Chemical Washer with water to make Clean Slurry.. The Clean Slurry can then be crystalized by the Chemical Crystalizer into Crystals.. Both Clean Slurrry and Slurry can be transported with Pressurized Tubes

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Slurry from the grinding circuit, at approximately 35% solids and 80—85% passing 135 mm is pumped to three thickeners. Thickener underflow, at approximately 54% w/w solids, is pumped to a train of four acidulation tanks. Sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit. Process air is also injected into the acidulation tanks to aid ...

OPP-Wet: Slurry Preparation Plants | Oil Sands Magazine

Once oil sands feed is received from the mine and broken down on the dry-side of OPP, the ore is then mixed with hot/warm water to produce a dense slurry. The technology used to slurry the oil sands varies between the operator, but the objective of OPP-Wet is the same: produce an aerated pumpable slurry and remove any oversized material that may damage downstream equipment.
