Read Part 2 of this paper: Increasing cogeneration in Canadian pulp and paper mills: Part 2 – New installations in non-kraft mills. Abstract. With Canada's 2050 net-zero emissions target, pulp mills must adapt to increased carbon taxes, potentially higher biomass costs, and the possibility of becoming a negative emissions industry.

Three key areas of C.I.P. plant design, viz. leach- ing time, adsorption and the gold loading on the carbon, are discussed and illustrated with examples. The need for accurate pilot plant data for use in assessing and optimising design is emphasized. This approach should minimize capital and maximise return on capital. It is demonstrated that, as regards adsorption, economics favours …

The gold CIP (Carbon-in-Pulp) processing is widely used to extract gold from ore. It mainly involves using activated carbon to adsorb gold from a cyanide solution, then eluting and regenerating the carbon for reuse. It is mainly suitable for beneficiating gold-containing oxidized ore with high slime content and containing carbon ore.
