50 Ib/Hour Regeneration Kiln A carbon regeneration kiln process uses heat, time and tumbling to regenerate exhausted carbon. The carbon is regenerated by rotating and tumbling the carbon particles at high temperature over time. Residence time in the kiln is determined by a combination of the rotating speed of the tube and by the pitch of the tube.

Rotary kilns have been in service in the gold industry to regenerate carbon for 65 years. At the time oxide ores with gold head grades of 8 to 10 g/t were being treated. Carbon could be regenerated adequately at 650C and solution losses were less than 1%. Forty years ago, research indicated that heavily fouled carbon from flotation circuits had to be held at …

movement of adsorbates (species that will be adsorbed by the carbon, e.g. gold) into the activated carbon granules. Mesopores (100 Å to 500 Å) these are the pores that branch off the macropores that serve to allow the adsorbates to leave the macropores Micropores (8 to 100 Å) which are of the right size to allow the adsorbates to be strongly
