High-rate Gold Loaded Carbon Elution Column and Electrowinning Cell Plant 1.1 Elution CN- or OH- dissolved in desorption solution is easier than Au(CN)2- to be absorbed by the activated carbon which causes Au(CN)2- absorbed on loaded carbon is replace by CN- or OH- and the reversible balance of of gold adsorption is broken.

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%) …

Stripping. Stripping is a process by which a solute is transferred from a liquid phase to a gas phase. This process involves the use of a gas stream to remove the solute from the liquid phase. The gas used for stripping is chosen based on its ability to absorb the solute of interest and its physical and chemical properties.

By pressurising the electrowinning cell, the gold-cyanide complex in electrowinning is destabilised and increases the electrowinning efficiency, lowering solution tenors returning back to the elution column and providing the optimal kinetics for rapid eluting of the precious metals off the loaded carbon.

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.

At a minimum the air stripping tower manufacturer shall have 5 years of experience in the manufacture and supply of air

What is Steam Stripping? Steam stripping, also known as steam distillation, is an affordable, one-step solution to cleaning volatile organic compounds (VOC) from plant wastewater streams. Typically, wastewater feed streams enter a distillation column at the top and flow downward, while steam enters the column at the bottom and rises.

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. …

Atmospheric Zadra Stripping Unit: The eluant strips the gold from the loaded carbon below the boiling point. The system operates at a proper flow rate for longer time. The advantages are less safety requirements and low capital costs. Pressurized Zadra Stripping Unit: The eluant is heated to 140°C to rapidly desorb gold off the loaded carbon ...
