Adsorption / Active Carbon - Lenntech

Activated carbon adsorption. Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process active carbon is the solid. Activated carbon is produced specifically so as to achieve a very big internal surface (between 500 - 1500 m 2 /g). This big internal surface makes active carbon ideal for ...

Extracting Gold By Carbon In Pulp - Blogger

Two main methods Carbon In Pulp (CIP) and Carbon Columns may consist of the most widely used technique for extracting gold today. Both methods use a large tank in the column parallel step where gold is dissolved in the slurry ( pulp) through a chemical process and combine agitation , oxygen and cyanide .

To do this, the carbon is dipped into a solution of about 5% hydrochloric acid and left there until the effervescent reaction stops. Alternatively the carbon can be placed into an acid washing column and the dilute acid then pumped into the column to cover it. The process normally only takes less than an hour.

DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND CARBON-IN-LEACH ...

Abstract - Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carbon-in-pulp process adsorption occurs after the leaching cascade section of

Description:In the process of gas absorption, a mixture of gases is contacted with a liquid, for dissolving one or more components of the gas to the liquid solution. In this process air is introduced into the bottom of the packed column. For the liquid phase, water is pumped to the top of the column where it falls through the packing material.

Au Recovery Using an Activated Carbon Column | SpringerLink

The feasibility of a process involving the use of activated carbon in a multistage column (NIMCIX contactor) for the recovery of gold from unclarified pregnant solutions was investigated on pilot-plant scale. It was found that satisfactory extractions, corresponding to a recovery of 99.6 percent, can be achieved with an average gold concentration of 0.0077 p.p.m. in the barren solutions from a ...

Design and Control of a Methanol Reactor/Column Process

This paper studies the process to convert synthesis gas into methanol. A cooled tubular reactor is used to react hydrogen with the carbon monoxide and carbon dioxide in the synthesis gas to produce methanol. Water is a byproduct. The gas-phase exothermic reactions are conducted in a packed tubular reactor, which is cooled by generating steam.

activated carbon is obtained and by column elution method the loaded gold is gained by stripping it from carbon. To prevent the granulated carbon to move forward with the slurry, special sieves exist at the tanks discharge openings. Next, carbon is driven backward by special carbon pumps at certain times.
