A company’s gold and silver refining and waste gas treatment project
A company’s gold and silver refining and waste gas treatment project

This project is an EPC (Engineering, Procurement, and Construction) project for gold and silver refining, encompassing workshop design, equipment production, installation, commissioning, and process training. The raw materials are refined gold and crude silver.

Spray tower exhaust gas treatment process
Spray tower exhaust gas treatment process

Our client signed a contract for palladium refining and waste gas treatment. Each batch can refine 10-15 kg of palladium. Glass reaction vessels and storage tanks are used, ensuring the entire reaction process is transparent, easy to clean, and free from pressure buildup.

Waste gas treatment project for refined lead and rare precious metal plants
Waste gas treatment project for refined lead and rare precious metal plants

It includes nitrogen oxide and acidic waste gases generated from processes such as gold mud nitric acid removal, aqua regia dissolution, sodium sulfite reduction, gold electrolysis, silver nitric acid dissolution, and silver electrolysis. It is particularly effective for high-concentration nitrogen oxides generated during the gold mud nitric acid removal, aqua regia dissolution, and silver nitric acid dissolution processes.

A company’s comprehensive refining and recovery project for precious metal catalysts
A company’s comprehensive refining and recovery project for precious metal catalysts

A certain company is a technology-based enterprise specializing in the research and development and production of precious metal catalysts. Relying on the strong R&D capabilities and state-of-the-art research instruments of Zhejiang University of Technology, the company utilizes unique solvent-free catalysts, allowing for multiple recycling of its products.

Problems arising from the production of high current density electrolyzers
Problems arising from the production of high current density electrolyzers

While ensuring the quality of high-current-density electrolytic cells (national standard No. 1 silver) and normal equipment operation, maximizing current density is a continuous development direction for silver electrolysis technology.

Platinum-Palladium Precious Metal Refining Tail Gas Treatment Project
Platinum-Palladium Precious Metal Refining Tail Gas Treatment Project

This project officially commenced operation in April 2021, treating tail gases from silver refining and platinum-palladium refining in Workshop 1 of the smelter. These include high-concentration nitrogen oxides from silver dissolution with nitric acid and alkaline waste gas from the platinum-palladium complexation reactor.

wet leaching process for precious metal purification

Wet leaching of precious metals: The essence of wet leaching technology is to directly dissolve aluminum group metals from a carrier using hydrochloric acid and a strong oxidant or other special chemical reagents (such as cyanide), and then further enrich and extract platinum group metal products from a low-concentration bath.

Smelting and enriching gold and silver from electronic waste promotes the recycling of precious metal resources.

Plasma arc melting, using a plasma arc as a heat source, is a highly efficient pyrometallurgical technique. It has applications in machinery, metallurgy, and aerospace, and is particularly suitable for producing high-melting-point metals and special functional alloy materials and devices.

Precious metal phase reconstruction smelting – extraction of platinum group metal ores

The ferroalloy phase is remelted and spray-dried into powder using standard equipment under an inert atmosphere, and then leached with dilute sulfuric acid at room temperature; the leaching reaction is very rapid.

The new high-efficiency silver electrolytic cell has the following advantages

Based on extensive practical experience from numerous manufacturers, the following advantages have been identified: environmentally friendly, labor-saving, time-saving, energy-efficient, and ensuring stable technical parameters.
