Washing Thickener For Impurity Removal High Performance. Washing systems. Rake thickeners are designed specifically to deal with high volumes of slurry. The integral scrapers aid transportation of material from the periphery of the tank to the outlet thus accelerating the removal of sludge from the thickener.

Thickeners ‘ a mysterious black box. Most of the world’s minerals pass through solid-liquid separation in a thickener at some point in their processing. Thickeners are used to either: concentrate mineral slurries prior to extraction of commodities; create a liquid free of solids for subsequent extraction of dissolved metals
5. ALGINATE 5.1 Alginate production methods 5.1.1 Sodium alginate "Alginate" is the term usually used for the salts of alginic acid but it can also refer to all the derivatives of alginic acid and alginic acid itself; in some publi ions the term "algin" is used instead of alginate.
Highly aerated thickener feed that makes its way into the body of the thickener tends to carry fine particles to the surface of the thickener to form froth. This froth causes issues such as the loss of product to thickener overflowon product thickenersand can cause reduction in thickener underflow density due to poor flocculation.
In the gold industry for instance the rule of thumb is a tonne of water for a tonne of ore. This bulk of water has to be separated or reduced for down stream treatment for recovery of the mineral in the ore. The separation of solids from liquids is usually achieved by gravity sedimentation in thickeners. For fine particles this is a slow process.

Our water clarifying tanks . SOTECMA has thickener from 6.5 to 14 m in diameter where you can treat from 150 to 800 m3/h of water contaminated with fine solids.. As auxiliary equipment a chemical flocculant dispenser can be supplied which increases the rate of sedimentation of the fine particles and therefore the clarifi ion performance of the water in the process.
Extraction Plant performance is measured by1the quality of the froth produced and2the fraction of bitumen recovered. BITUMEN FROTH QUALITY EXPLAINED. Froth quality is a very important performance metric for any oil sands Extraction plant. There are 3 components found in bitumen froth:1bitumen2fine solids and3water. 1.
Continuous thickening by an operation called sedimentation is the separation of suspended solid particles from a liquid stream by gravity settling. The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants. The
The existence of the density difference is therefore a necessary pre-requisite in sedimentation. Gravitational settling of particles in liquids is an age-old process which can be used for a variety of purposes. For example it is used for the classifi ion of solids washing particle size measurement or mass transfer and in solvent extraction.

A continuous process for extraction of bitumen from oil sand by a hydrocarbon solvent wherein the sand is classified so as to produce a major coarse fraction and a minor fines fraction with both fractions contacted with solvent to wash miscella therefrom and wherein the major coarse fraction is contacted with solvent by gravity percolation and the classifi ion of the sand is effected to .
Percolation 1. PERCOLATION Presented by: Hassan MuJtaba 43-E-14 2. INTRODUCTION ‘per’ means ‘through’ ‘colare’ mean ‘to strain’ Definition The process in which a comminuted drug is extracted of its soluble constituents by the slow passage of suitable solvent through a column of drug.

Finely divided magnetite prepared by washing with a solution of sodium hydroxide at high pH is applied to the water together with a small concentration of aionic polyelectrolyte . The magnetite particles absorb colour-producing dissolved organic substances and attract fine colloidal particles.
In the process of washing activated carbon a dilute hydrochloric acid solution3%is circulated/pumped into the elution column. The acid dissolves inorganic foulants such as calcium carbonate magnesium and sodium salts fine ore Minerals such as silica and fine iron particles. The carbon acid wash cycle takes about 4.30 hours. Acid washing .
In high compressionHCTand pastePTappli ions the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved. By adding flocculants and increasing the depth of the solids bed in thickeners higher degrees of separation can be achieved.
