Carbon Processing

SPENT CARBON PREPARATION AND TREATMENT

  • Upon receipt of carbon materials, the customer and/or representative is contacted to confirm receipt and set up a weighing and sampling date.
  • Carbon materials are received in the presence of a customer or representative and a JRI consignment note is issued.
  • Each super sack of carbon is lifted from the pallet and placed on the JRI certificated scale to determine a net weight.
  • Each super sack of carbon in the batch is auger sampled. One gram sample is taken for each pound of weight. Nine to twelve auger holes are made per super sack. Particular notice is taken to get the auger down to the bottom of the super sack.
  • The weighed sample from each super sack is placed in a mixer.
  • The bulk sample is blended for twenty minutes.
  • The carbon sample is poured out of the mixer into sample buckets.
  • In the event of excessive moisture the carbon sample is placed on a rubber mat and a sample is cut by cone and quartering.
  • Where there is no excess water, the sample is passed through a riffle splitter.
  • The sample is cut down to four equal samples. (1) Customer (1) JRI (1) Umpire (1) Reserve
  • Samples are sealed and accurately represent the weight, analysis and value of carbon.
