Cooling water enters near the bottom of the vessel, cools the carbon and mostly exits with the carbon the balance- moving up the column with the eluate. The process uses similar eluates to those described by J.B. Zadra (1952), and uses higher temperatures and pressures to accelerate the rate of stripping as described by J.R. …

Air stripping columns are most widely used for the removal of volatile organic compounds (VOCs) from water. By forcing air through contaminated water, the VOCs are evaporated from the water and the air passing through the column absorbs the contaminated vapor. ... Geometry and tray placement must be specific, often designed by the manufacturer ...
The liquid reaching the bottom of the column is partially vaporised in a heated reboiler to provide reboil vapour, which is sent back up the column. The remainder of the bottom liquid is withdrawn as the bottom product. The vapour reaching the top of column is cooled and condensed to a liquid in the overhead condenser.
Fig. 2 Batch Distillation with Rectifying Column The liquid mixture that is to be processed is known as the feed and this is introduced usually tray known as the feed tray. The feed tray divides the column into a top (enriching or rectification) section and a bottom (stripping) section. The feed flows down the column where

Initially, bottle cyanidation tests are conducted on 200- to 500-gram charges of ground ore to determine the degree of gold extraction and reagent consumption. If the gold content of the ore is leachable at a …
The recovery of gold from secondary resources has significant implications for both the environment and the economy. In this paper, using four types of polyphenols including 4,4′-oxydiphenol, 4,4′-methylenebisphenol, 4,4′-thiodbisphenol, and 2,2′,4,4′-tetrahydroxybenzophenone as the organic ligand and Cr(NO 3) 3 ·9H 2 O as the metal …

Stripping of gold and silver from carbon is effected by means of two main processes (AARL and ZADRA). The main rate-enhancing parameter in the stripping of gold and silver is temperature. A secondary rate-enhancing parameter is ionic strength. (1) Stripping is usually conducted within a solution containing sodium cyanide (0.1 – 0.5%) …

A wide range of columns: graphite, tantalum, Titanium, Zirconium, PTFE, PFA… Mersen designs and manufactures columns (including internals and packing) in graphite, PTFE lined, reactive metals (tantalum, zirconium) and metals (titanium, nickel alloys, stainless steel, carbon steel) compliant with demanding process constraints such as …
Distillation is a process by which a liquid mixture is separated into fractions with higher concentrations of certain components by exploiting differences in relative volatility. In industrial settings such as oil refineries and …
y i = composition y i of the component in the stripping gas (molfraction). The desorption becomes greater and the rest loading x i in the liquid becomes smaller:. with greater values for H and γ: absorption media and high temperature in stripping. at low y i values in the stripping gas: stripping gas cleaning and high flow rate. with decreasing total pressure …

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ... Gold …
In gold recovery applications, activated carbon manufactured by Thermal activation is used.

The temperature at which activation is carried out is between 800 to 1000 °C. In this
Counterflow stripping columns are the most common design because of the high efficiencies that can be achieved, combined with the low air volume required. Air volume is important, because in many cases the air will …
Graphical Method to Find Equilibrium Stages for Absorption Columns = equilibrium constant, (mole fraction in gas)/(mole fraction in liquid) = liquid flow rate (mol time-1) = liquid flow rate on a solute-free basis (mol time-1) = total number of stages. For an absorption column, is the bottom stage. For a stripping column, is the top stage.
