In a jewellery factory working with gold, employing many people, it
is of the first importance, to keep a daily record of the weight of
gold issued to each worker compared to the weight of the finished
work plus all off cuts and filings when the work is given back to
you on completion. this will identify whether gold loss is taking
place through workers keeping gold for themselves.
You will need to assay on a random basis each workers returning
gold. The workshop floors need to be of a cotton woven material on
top of plastic sheeting so the gold dust can be recovered from
burning the cotton to ash.
Also it is usual for there to be special long U traps in the waste
water system to recover gold from hand washing. Then there is the
gold to be recovered from a central vacumn system connected to each
polishing, and or sanding machine. Also each work bench has to have
its proper apron to catch all filing and sawings.
The workers need to remove outside shoes and wear inside shoes you
supply so gold on the shoes can be recovered. Finally work overalls
need to be issued by you and washed by you to recover the gold on
them.From the above it is therefore possible to make your business
calculations to decide on the correct pricing of your work and to
establish the causes of gold loss.
Hope this helps.
