New type of gold electrolysis equipment:

The system features an integrated, unified design that includes individual electrolytic cells, circulation pumps, rectifiers, automatic electrolyte replenishment systems, smoke gas condensing recovery systems, temperature, voltage, current, copper discharge temperature monitoring systems, and data recording systems.

The rectifier is separately enclosed and isolated from the workshop's acid fumes, ensuring a long service life.

The platinum refining process

employs the ammonium chloride repeated precipitation method. The number of precipitations is determined based on the analysis of impurities in the sample.

recovery process of platinum and palladium from silver electrolysis anode slime

The majority of platinum and part of the tantalum in the impure silver anode remains in the anodic slime. generally, platinum and palladium in the anodic slime are recovered.

Recovery process of platinum and palladium from silver electrolyte

When silver is electrolyzed, some tantalum from the impure silver anode will enter the electrolyte. Due to the similar electrode potentials of tantalum and silver, when the concentration of tantalum in the electrolyte exceeds 20 ppm, it will be deposited on the cathode.

Wet Method Refining Gold Production Process (gold mud)

Separation of Silver: Nitric acid is used to remove silver from gold, separating them.

Dissolution and Reduction of Gold: Sodium thiosulfate solution dissolves and reduces the gold from its compounds.

Post-Reduction Processing of Mercury and Platinum Group Metals (PGM): After reduction, mercury and platinum group metals are separated through a roughing process to isolate the PGMs from the filter residue.

Wet Method Refining Gold Production Process (Crude Gold)

Using raw gold as raw material, the process involves powderization, acid cleaning, and a single reduction to achieve gold with a purity of 99.95% or higher in one step. A second reduction is required for the refined gold powder, which needs to be re-dissolved to reach a purity of 99.5% or higher.

The acid cleaning solution requires to chlorinate silver precipitation, and the resulting filter residue undergoes iron powder substitution.

Refining Gold Electrolytic Production Process

Using crude gold as the anode, employing a high-current-density electrolysis technology, produces stable electrolytic deposits of gold with a purity of 99.99% or higher on the cathode.

The anode is re-melted for recycling in electrolysis after cleaning.

High-gold anode residue is cast for recasting, and the platinum-tantalum residues in the anode residue are recovered using wet methods.

High-Efficiency High-Purity Silver Electrolytic Production Process

Using either a Dore metal or crude silver as the anode and silver nitrate (AgNO3) as the electrolyte, employing a high-current-density electrolysis technology, produces silver powder with a purity of 99.99% or higher.

After cleaning the anode, it is directly placed into the anodic electrolytic cell to produce silver powder with a purity of 99.99% or higher.

Waste electrolyte undergoes oxidized silver purification, achieving purified electrolyte standards before recycling for reuse in electrolysis.
