2020 Newest copper sulfate solution equipment from Scrap copper
Introduction of copper sulfate solution equipment from scrap copper:
Due to the stable chemical properties of metal copper, it is poorly soluble in non-oxidative acid liquor. It is the most common soluble copper method to add oxidizing agent.
It is generally believed that copper dissolution in acid liquor containing air is a typical electrochemical reaction process, thus appropriate amount air can ensure oxidation potential of solution to facilitate the reaction.
II. Main technical and economic indicators
Copper dissolution speed: ≥12kg/h·m3;
Power consumption (ton copper): ≤400kw·h;
Direct recovery rate: 99.9%;
Flue gas (H2SO4): ≤50mg/m3
Leaching test of of copper sulfate solution equipment from scrap copper
(I) Laboratory test
1. Red alloy can be leached smoothly in dilute sulfuric acid media taking air as oxidizing agent, and leaching efficiency is more than 99.5%.
2. Acidity after leaching is between 10～25g/l.
3. Extraction temperature at 75℃～85℃ can get high leaching speed.
4. The leaching agent has favorable filtering performance.
(II) Leaching reaction mechanism
(III) Pilot equipment
Microbubble neutralizing tank consists of reactor, water-gas ejector, liquid-gas separator (buffer) and circulating pump.
The of copper sulfate solution equipment is equipped with other parts as follows:
①.Spiral-flow solid-liquid separator.
② Acid mist condenser.
③ Liquid level controller.
④ Drain outlet.
(IV) Pilot process
Materials: use red alloy in original state, no requirement on particle size.
Pre-leaching solution: H2SO4160～210g/l; reaction temperature: 75℃～85℃;
Solution replacement speed: 4～7l/min; acidity of leaching liquid: 15～30g/l
Conclusion and prospect of copper sulfate solution equipment from scrap copper
1. Daily average leaching capacity is 460kg (design standard>500kg);
2. Leaching power consumption of ton alloy is about 450kwh (design standard≤400kwh);
3. The equipment can realize self-heating start and operation if there are some problems.
4. Low acidity oxidation leaching process of red alloy in H2SO4 medium is feasible.
