Q: Hi, My name is Raed, and I have 20% oxidized copper mine. The way I work is to extract and add 15% sulfuric acid in an electrolytic metallurgical plant. Everything is fine, but my only problem is that copper precipitates quickly and does not stick to steel. What materials do you need to add cooling solutions? I want a solid cathode. Thank you.
A: 1. Did not use copper leaching solvent to extract the copper ion out to get pure copper ion, then get cathode copper by Electrowinning process.
2. Please check whether the connect of positive pole and negative pole is inverse.
3. If the copper is deposited, it means the acidity is not enough.
We need learn about more detailed condition to confirm the problem.
Q: The problem is that copper ions quickly deposit on the surface of the cathode steel and then quickly detach. There is strong vitality in the solution during electrolysis. It should slowly precipitate until the cathode form is harmonious and sturdy.
A: 1. The density of current is too high, it should be 150A/m2.
2. The flow rate of electrolyte is too small. The flow rate of electrolyte should be 12 L/min.
3. The copper concentration’s difference of inlet and outlet in the electrolyte should between 2-3 grams per liters, over this range the copper can’t be supplied enough.
4. The minimum concentration of copper in the electrolyte should be kept more than 35 grams per liter.
Q: Do you have the the technology of generate electricity by copper sulfide ore?
A: Yes. Some copper mine does not have power supply, we have advanced technology can generate electricity and make sulfuric acid, can solve the all problem of power supply and raw material. The producing technique as below:
There are more than 20% content sulfur in Copper sulfide powder, if we burn it through low temperature at beginning, sulfur will be fired itself then produces a lot of heat, the high pressure of steam shell be about 40 kg, the energy is able to generate electricity, also can produce the gas of sulfur dioxide, it can be disposed by water then become to sulfuric acid. Burned powder become to copper oxide, can mix with sulfuric acid to produce electrical copper through stirring and leaching process.
Q: What is lowest investment for copper mine development?
A: If you have copper ore and place, we can invest a low investment technology to get high content copper-ferro alloy, you supply copper ore and place (factory), we in charge of others, when we sell the production (copper-ferro alloy) out, we can separate the benefit.
This is a very good business, copper-ferro alloy easy to sell out in your area or China.
Q: If C272 is corroded in acidic solutions containing chlorine, sulfur, etc., resulting in a decrease in its extraction efficiency and even inability to function properly. What should I do?
A: If C272 is corroded in acidic solutions such as chlorine and sulfur, resulting in a decrease in extraction efficiency and even inability to function properly, the following solutions may need to be considered:
Adjusting acidity and concentration: When using C272 in acidic solutions, the degree of corrosion can be reduced by adjusting the acidity and concentration. Reducing the acidity or concentration appropriately can reduce the damage to C272 and improve its extraction efficiency.
Replacing the extractant: If C272 has failed and cannot be repaired or regenerated, we may need to consider replacing it with another extractant suitable for the working environment. For example, extractants with better acid-base stability and corrosion resistance can be selected based on actual conditions to ensure their stability and reliability under strong acidic conditions. Our DZ272 extractant has stronger acid resistance and will not emulsify in environments with high iron ion concentrations.
Strengthening maintenance and upkeep: The management and upkeep of extractants are crucial for ensuring their normal operation and extending their service life. Equipment should be regularly inspected and cleaned, the quality and concentration of extractants should be tested, aging extractants should be replaced in a timely manner, and anti-corrosion measures should be strengthened to reduce the risk of corrosion of extractants.
In summary, by adjusting the process and enhancing maintenance appropriately, we can avoid damage to C272 in strong acidic environments and ensure its normal operation and efficient extraction.
As shown in this figure, the biggest advantage of our DZ272 extractant is its strong iron resistance, which can withstand up to a concentration of 3.5g/L iron ions. At this concentration, the extractant will not exhibit emulsification and phase separation. However, the 272 from other manufacturers can only reach a concentration of 1.6g/L iron ions. Beyond this concentration, the extractant will emulsify without phase separation.
Q: What kinds of extractant should be used for Nickel Cobalt extraction?
A: This is decided your raw material, if it is laterite nickel ore, there are too much impurities, should use D2EHPA to remove the impurities first, then use DY319 to extract nickel and cobalt out together, then use DY272 to extract cobalt out, only leave nickel.
If your raw material is lithium battery materials, the material is pure, only need use DY319 to extract nickel and cobalt out together, then use DY272 to extract cobalt out, then leave pure nickel ion.
