How can we recover all the lead from old car batteries?

AI Thread Summary
Recovering lead from old car batteries is challenging due to the corrosion caused by sulfuric acid, which converts metallic lead into lead compounds like lead sulfate. Attempts to extract lead by melting often yield minimal results, as only a small amount of lead can be recovered. Electrolysis can potentially convert lead compounds back into metallic lead, but this process requires an electrolytic cell and strict safety measures due to the hazardous nature of the materials involved. The discussion highlights the difficulties in lead recovery and the need for proper techniques to handle battery components safely. Overall, extracting lead from old batteries is a complex and messy process that should be approached with caution.

Years ago I thought I would take apart a car battery melt all the lead I thought there would be at least 10 or more pounds of lead I only got a little over a pound of lead there was a lot of heavy dirt but applying heat to this material yielded no lead it seems the acid eats or corrodes the lead is there any way to recover all the lead that goes into a new battery from an old one?

Electrolysis has converted the metallic lead to a lead compound (lead sulphate? I think). To get the lead out of that grey goo, you would need an electrolytic cell. Messy business and not to be undertaken without the right safety measures.

I once tried to explain to someone why run-on sentences could get to be very hard to follow guess he didn't learn much in what used to be called grammar school could be because he was thinking of something else at the time hard to say don't know what else to think it was a lost cause even though i tried my best maybe could have done better.

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
