Nickel electrowinning technology
Technical Overview
This technology is mainly aimed at solving the difficulties and pain points of traditional nickel electrodeposition process and technology, which has been researched and developed by our for 10 years.In october 2023, it passed the scientific and technological achievements evaluation of China Non-ferrous Metals Industry
Association, and the evaluation conclusion is that it has reached the international advanced level.
It includes new pattern of nickel diaphragm frame and its structure, acid fog extraction technology from sealed anode frames, anolyte outlet and acid fog extraction connecting devices, new-patterned anode chamber intake way, multi-circuit conduction technology and devices which applying for nickel EW production lines and integrated
directional position devices and other process technology package.
System Features
1. Environmentally Friendly And Safe
It completely solve the problems of acid fog during production. The acid fog level in plant with1 meter above cells during site checking was no higher than 0.005 milligram per cubic meter.
2. Excellent Product Quality
It adopts new patterned feeding mode and increases cathode feeding circulation volume, reducing concentration polarization.
By controlling anolyte volume and acidity via controlling electrolyte height and level difference during EW process, it can improve the crystal quality of nickel products.
The first grade rate has increased from 30-50% of the current industry to more than 90%;The chemical composition of nickel can reach 99.99%;Its products with smoothing edges without bubbles at the bottom or liquid,
3. High Single-Tank Capacity
The operating current density has been increased from 180A/㎡ to 230A/㎡ with the increasing area of each cathode plate from 1.5 ㎡ to 1.8 ㎡.Single tank capacity can be increased by 40%.
4. Low Operating Costs
Cell voltage was lower by 0.1-0.2V with reducing operation energy consumption. Electricity efficiency was improved from its of traditional way’s 85%-90% to 92%-95%. The consumption of diaphragm bag was lowered form 0.6pcs l to 0.1pcs per ton of
nicke for products.
5. More Convenient To Operate
It uses separated-structure diaphragm. Operators and site workers operates and maintain the production line conveniently, even if operators randomly take out certain diaphragm during production process.
6. Intelligent Manufacturing
Based on the intelligent electrolysis process of the central control platform and big data monitoring ER process, we constructs the trinity detection system with this technology package of cell temperature, cell pressure and short-circuit, and the intelligent upgrade channel is reserved for remote consultation and pressing one-key to realize intelligent flexible production.

Reference Projects
Nitrogen oxide treatment solutions
Scheme Features
1. High absorption efficiency and treatment meets standards.
High-efficiency absorption,Absorption efficiency is up to 99.5%,the concentration of nitric-oxide release≤200mg/m³
2. Zero pollution, zero emissions
Zero pollution,zero release. No polluted wasting water,also no secondary pollution
3. Low investment and operating costs
Reducing agents are economical and readily available, and the treatment cost is generally 50-80% of that of the traditional alkaline absorption method.
4. High integration and great operational flexibility
Each absorption and treatment unit of the device is an independent mechanism that can be operated and controlled separately, ensuring that the outlet exhaust gas meets emission standards under the most economical conditions; maintenance and adjustment do not require the entire system to be shut down, ensuring continuous absorption and treatment.
5. Corrosion resistant and long service life
Anti-corrosion, long working life.Working life of installing main part device can reach up to 10 years.
