What issues should be considered when launching a new electrolytic copper project?

Resources are the key, the inherent conditions. Deficiencies from birth are hard to make up for later in life. It can be said that resources determine success or failure! Secondly, process technology, process design, equipment selection, site selection, layout and transportation, energy supply... and so on

The newly built copper electrolysis workshop includes a liquid purification workshop and a comprehensive recycling workshop. Points to note: 1. Process selection and requirements 1. Selection of the process for the copper electrolysis workshop: Decide whether to use a stainless-steel permanent cathode electrolysis process or a traditional electrolysis process. 2. Design Parameters 2.1 Determination of production scale ； 2.2 Annual production days: 330 days ； 2.3 Current density 260 A/m2. 2.4 Composition of the anode plate　　　　　　　　　　　　　 % Composition Cu Pb Ni As Sb Bi Fe Content >99.0 <0.15 <0.20 <0.10 <0.10 <0.02 <0.10 3. Requirements: The feasibility study report must be prepared in strict accordance with relevant regulations; in addition, the following issues also need to be taken into consideration. 3.1 Electrolysis Workshop 3.11 Comparison of the advantages and disadvantages of the stainless steel permanent cathode electrolysis process versus the traditional electrolysis process, as well as a comparison of their technical and economic aspects ； 3.1.2 Comparison of the advantages and disadvantages of the ISA, KIDD, and OT processes for permanent cathodic electrolysis using stainless steel, as well as a comparison of their technical and economic aspects ； 3.1.3 Comparison of stainless steel cathode edge banding types, service life, and performance ； 3.1.4 Detailed Process Flow ； 3.1.5 Comparison of electrolyzer selection, corrosion protection, and circulation methods ； 3.1.6 Selection, quantity, function overview of main equipment, and manufacturer? Analysis of domestic and foreign suppliers? (Technology and Cost) ； 3.2 Selection and Requirements for Electrolyte Purification Processes 3.2.1 Which purification process should be chosen for the electrolyte? Comparison of adaptability and flexibility ； 3.2.2 Process requirements: Design the copper sulfate production process such that the copper sulfate meets national standard Grade 1, with a purity of 96%. It should also be taken into account that this production process is activated only when the price of copper sulfate is high; otherwise, it is not utilized ； 3.2.3 Raw materials added for copper sulfate production ； 3.2.4 What are the contents of various components in the nickel-free liquid produced by the purification process? It is also required that the liquid after nickel removal be returned to the electrolysis circulation system ； 3.3 Selection of processes for the comprehensive recycling workshop. 3.3.1 Selection of the anode slime treatment process flow. Analysis and comparison of anode slime treatment process routes to select the appropriate one ； 3.3.2 Considering the treatment methods for arsenic during the electrolysis process and environmental protection issues, whether it can be recycled or converted into stable compounds ； 4. Plan the staffing for each position in each production workshop. 5. Environmental protection issues in the wet processing workshop. 5. Investment forecast: specific investment amount for each project (including the electrolysis, liquid purification, and comprehensive recovery workshops). 6. Circular economy aspects: such as the treatment processes for ash and slag generated during melting. 7. Is the design for auxiliary facilities (such as boilers, power supply, etc.) carried out simultaneously? 8. Timeline for feasibility studies, costs, and coordination with the preliminary design, as well as the construction period. ________________________________________

It is essential to select appropriate processes and design solutions based on the raw materials and conditions; different technical parameters should be used according to the scale of production. Cost, environmental impact, and comprehensive recovery must also be taken into consideration.

First, it is necessary to determine whether to use wet or dry methods, as well as whether to use raw ore or recycled materials, before deciding on the process scheme. If there are sufficient mineral resources available, crude ore can be considered; currently, the more advanced production technology for crude ore is the Shuangshan technology used by Shandong Xiangguang Copper Industry. Currently, the new 200,000-ton copper project is led by Fujian Zijin Mining. Western Mining’s 200,000-ton recycling project in Tianjin has been launched.

Whether there is a profit margin should always be the top priority; technical issues can be resolved by professionals, and there are many experts in our forum

I specialize in extraction tanks and mixing drums; feel free to contact me if you’re interested.

Haha, the summary is already written. I approached it from a quality perspective: raw material quality – establishing product quality standards – designing production capacity – selecting manufacturing processes – planning the layout – choosing equipment – determining staffing needs – compiling a list of project costs; then market research – cost estimation – profit margins; followed by starting production, process tuning, improving production capacity, upgrading product quality, and paying salaries: lol

I fully agree with the views on raw materials, production processes, supporting facilities, purification processes, and overall profit margins! I'm sorry! I’m talking nonsense! ......

What was said upstairs is all very important, but without determination, it’s likely that nothing will get done. It’s relatively easy to build a factory these days; those who are not in the industry can opt for the EPC approach. Finally, all that’s left is for you to take care of it.

I think resources are what matter most; the manufacturing processes are already well-developed. In the years we have been dealing in copper and nickel, there has always been a demand for these products, but raw materials represent a bottleneck
