melt time to get from bars to molten 5 - 10 minutes
atomizing 2 t.o/second
settling, majority 15 minutes, balance 24 hours
digestion 30 minutes
filtering chlorides (about 85 gallons acid) 30 - 45 minutes
PGM Drop 5 minutes*
filtering again same as before
gold gassing 45 minutes
filtering again
washing gold 15 minutes
melt and pour 400 oz bars 30 minutes
total time around 6 hours
* if Pt , Pd is low in concentration it takes longer to re-settle and filter than it's worth, most want to ship their gold and be paid for it within 24 hours so cementation and collecting when it accumulates is a better use of time.
