Resin-in-Pulp

Technology by which gold is recovered from crushed ore by making it adhere to a special resin solution. The process was initially fully tested at the Muruntau gold mine in Uzbekistan in the 1970s as an alternative to the carbon-in-pulp process that was more widely adopted elsewhere. (Resins are small water-insoluble beads of plastic-like material used in ion-exchange columns for the collection of precious metals from solutions).
