B Leaching Drum Filters Of Pulp Plant
Comprehensive Guide to CIL Process
The first leaching tank in the CIL plant does not need carbon, and the 7 adsorption tanks add carbon. The volume of one adsorption tank is 98 cubic meters, 98*7=686 cubic meters, calculated based on 13 grams/liter, 686 cubic meters*13=9 tons of carbon, prepare 3 tons of extra carbon, a total of 12 tons carbon will be enough for one year.
