Battery acid?

The scrap price for lead is 7 cents per pound which I calculate would give about 91 cents per battery if I sold the lead back to the scrap yard each battery would cost $1.08 . After concentrating the acid each battery yields about a pint of fairly clean 90% acid. So the way I figure it I would pay $32.00 for the same 2 gallons of acid unless I

Foreign lead-acid battery refining [PDF]

6 FAQs about [Foreign lead-acid battery refining]

Can tin be retained in a recycled lead-acid battery?

Can tin be used to refining secondary lead?

The proposed method of refining secondary lead offers the possibility of using the tin already contained in the lead alloy, significantly reducing its consumption for the production of lead alloys for the battery industry. Instead of pure aluminium, aluminium scrap can be used successfully, provided its composition is controlled.

What are the basic parameters of a lead tin refining process?

The tests were conducted to determine the basic parameters of the process, such as the temperature, refining time, introduced additives, and methods of their application in terms of the efficiency of refining the lead–tin alloy and the degree of tin retention in the lead.

Did tin remain in lead during the refining process?

The chemical analyses of the lead taken during the refining process confirm that, in addition to the arsenic, the copper, nickel, and tellurium were removed during the initial period. Most importantly, however, is the fact that tin remained in lead, which is the basic premise of refining carried out in this way. Figure 12.

Should aluminium scrap be used for lead refining?

The costs of lead refining using aluminium scrap are higher compared to other classical lead refining methods . From an economic point of view, this new refining method is profitable to use when there is a significant amount of tin in the lead and relatively low contents of other impurities.

Can aluminium be used to refine lead?

Conclusions The work reported in the present paper has clearly demonstrated that refining lead from antimony, arsenic, copper, nickel, and tellurium with aluminium produces an outstanding result, and most importantly, virtually all the tin remains in the lead. Impurities can be removed to levels of a dozen or even less than 1 ppm.
