Hi teacher. can you answer me with details Of copper recovery? Q #1. what deference between copper oxide and sulfide? Q#2.is nitric acid good or sulfric acid for copper desolves? Q#3. i get copper powder from rock with both acids such as nitric desolve a lot of powder then sulfric. but nitric also desolve the iron rod or electrolysia metal😮. Q#4. how i can use zinc for recover from copper nitrate or sulfte. ?
I’m no teacher my friend but I will answer your questions to the best of my ability. Q1 Oxides can often be dissolved in weak acid, making copper recovery efficient. Sulphides, on the other hand, don't leach, so they require a different process. Oxides ultimately produce a high-grade copper cathode, while sulfides result in a concentrate which needs further processing at smelters. In terms of recovery; copper oxide takes a process involving a foundry (keeping the crucible covered) and carbon process to get copper metal. And copper sulfide has no oxygen element so oxygen is introduced By heating copper sulphide ores to produce copper oxide which is then treated with sulphuric acid to form copper sulphate. Once you have copper sulphate you can dissolve in water and cement it out with either aluminum or sodium bycarbonate (baking soda). Q2 Nitric acid is way stronger easier to dissolve with but way more expensive, even if you make it yourself it’s tough and time consuming. Sulphuric acid is harder to dissolve wit , but cheap. Done right both will dissolve good, then cement out of solution using the table of reactivity. Q3 Your anode (what ever metal you are using is always sacrificial; meaning it will always dissolve even with a graphite anode). This is why I started using a catch jar under my cathode to keep my pure copper separate from the trash iron and tin that was in the bar I purified in my videos. Q4 To use zinc you can use it as an anode like the iron rod in Q3, or in copper sulphide or sulphate,and nitric solutions you can rough up the surface and just drop it in to cement the copper metal out, because zinc is higher up on the table of reactivity.

Q1
Oxides can often be dissolved in weak acid, making copper recovery efficient. Sulphides, on the other hand, don't leach, so they require a different process. Oxides ultimately produce a high-grade copper cathode, while sulfides result in a concentrate which needs further processing at smelters.
In terms of recovery; copper oxide takes a process involving a foundry (keeping the crucible covered) and carbon process to get copper metal. And copper sulfide has no oxygen element so oxygen is introduced By heating copper sulphide ores to produce copper oxide which is then treated with sulphuric acid to form copper sulphate. Once you have copper sulphate you can dissolve in water and cement it out with either aluminum or sodium bycarbonate (baking soda).
Q2
Nitric acid is way stronger easier to dissolve with but way more expensive, even if you make it yourself it’s tough and time consuming. Sulphuric acid is harder to dissolve wit , but cheap. Done right both will dissolve good, then cement out of solution using the table of reactivity.
Q3
Your anode (what ever metal you are using is always sacrificial; meaning it will always dissolve even with a graphite anode). This is why I started using a catch jar under my cathode to keep my pure copper separate from the trash iron and tin that was in the bar I purified in my videos.

To use zinc you can use it as an anode like the iron rod in Q3, or in copper sulphide or sulphate,and nitric solutions you can rough up the surface and just drop it in to cement the copper metal out, because zinc is higher up on the table of reactivity.
