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 …

"Pulp mills are in an ideal situation to introduce gasification due to their ability to source woody biomass efficiently." The biomass Taillon refers to is mostly a low-cost biomass side stream from the woodyard at a pulp mill, for example, bark and chip screening rejects of various species that are ideal for the gasification process.
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.

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.
When carbon is being educted to the feed hopper the Linotex valve is fully closed and the 50 mm (2 in.) gate valve to the overflow (slops tank) is fully open. When excess water to the carbon is drained away the Linotex: valve is opened. The 25 mm (1 in.) valve with the quick-disconnect fitting is used when carbon hangs up in the hopper.
