AN ELEMENT IN THE PERIODIC TABLE

post-transition metal

Some Basics  Lead IT IS AN ELEMENT (Pb) (LEAD) IT IS AN ELEMENT (Pb) (LEAD) COMMONLY USED IN MANY APPLICATIONS FOR THOUSANDS OF YEARS (FALL OF ROMAN EMPIRE) COMMONLY USED IN MANY APPLICATIONS FOR THOUSANDS OF YEARS (FALL OF ROMAN EMPIRE) SOFT, EASY TO WORK WITH AND SMELT SOFT, EASY TO WORK WITH AND SMELT HIGHLY RESISTANT TO CORROSION HIGHLY RESISTANT TO CORROSION BATTERIES CONTAIN THE MOST LEAD TODAY BATTERIES CONTAIN THE MOST LEAD TODAY

TODAYS WORLD OF BATTERIES  Lead Acid Battery INVENTED IN 1859 BY FRENCH PHYSICIST GASTON PLANTE’ INVENTED IN 1859 BY FRENCH PHYSICIST GASTON PLANTE’ CONSISTS OF LEAD PLATES, SULFURIC ACID AND PLASTIC CONSISTS OF LEAD PLATES, SULFURIC ACID AND PLASTIC SLOWLY BEING REPLACED BY LITHIUM BATTERIES SLOWLY BEING REPLACED BY LITHIUM BATTERIES

WHERE DO OLD BATTERIES GO TO DIE?  LANDFILLS!  GARAGES!  CHINA & MEXICO!  U.S. RECYCLERS!!

LEAD AND BATTERIES ARE RECYCLED…………..  75% OF OLD CAR / TRUCK AND FORKLIFT BATTERIES ARE RECYCLED  PLASTIC IS USED FOR NEW BATTERIES  ACID IS USED TO MAKE SODIUM SULFATE (USED AS A FILLER IN DETERGENTS)  LEAD (Pb) IS SOLD TO BATTERY MAKERS

LEAD AND THE WORLD ECONOMY  LEAD =MONEY  GREEN / RECYCLING = MONEY  RECYCLING MEANS THOUSANDS OF JOBS

REFINERIES AND SMELTERS  APPROXIMATELY 8-10 STILL IN THE USA  NEW REFINERIES ARE NOW BEING BUILT IN MEXICO???  THEY REFINE MILLIONS OF TONS OF LEAD PER YEAR  LEAD SELLS FOR UP TO $1.50 PER POUND LBS IN A TON.

QUIZ  WHICH IS THE SYMBOL FOR LEAD? Hg, H2O, Be, Pb?  WHAT HAVE YOU HEARD ABOUT LEAD IN THE NEWS LATELY?  IS RECYCLING LEAD A GOOD PROCESS? WHY?  DO YOU KNOW WHERE ANY LOCAL REFINERIES & SMELTERS ARE LOCATED?
