Granular Activated Carbon

05/01/2007 11:58 AM

I am searching for an alternative use for Granular Activated Carbon. Other than filtration, what can I manufacture using large amounts of GAC. I've thought of Ceramics, Carbon Fiber products, plastic composites, manufactured lumber, fireproofing/heat resistant materials etc. but I really don't even know if these are possible or what the process would be to make it possible. Any info anyone could give me would be much appreciated.

I've recently been browsing www.graftech.com for carbon composite thermal materials - you might look there.

Hi TLD2,

I'm not sure what the specifications of your granular activated carbon are, but there is a general shortage of activated carbon in the gold mining industry (used in the CIS, CIL & CIP process).

Activated carbon (generally 8 X 16 or 6 X 12 # Tyler), is used widely in the gold extraction industry to adsorb the dissolved gold species AuCN. The carbon being much coarser than the finely milled ore (generally 75 % < 200 # Tyler), is screened out and the gold eluted from the carbon. The carbon is then reactivated and reused in the process.

Initial inventories are of the order of 50 to 150 tons and consumption of between 10 - 40 g/t treated (a 1 Mtpa plant would consume between 10 to 40 tons pa).

Important characteristics are hardness, abrasion resistance, activity and low platelet count.

Give me a shout if you think your carbon may be suitable.

Peter
