Ten Do's & Don'ts of Gold Gravity Recovery

April 12th, 2000

A.R. Laplante; McGill University, Montreal
Presented at Randol Gold & Silver Forum 2000
April 25-28th 2000; Vancouver, B.C. Canada

The ten guiding principles in the design and operation of gold gravity circuits are presented: economic impact, applied mineralogy, gold’s behavior in grinding circuits, alternate recovery approaches, reliability vs. performance, gold room operation, scale-up, screening, feed rate and recycling. The principles are explained and their application illustrated with case studies. Conflicts in principle application are also discussed.

This presentation will review practical considerations of the design and operation of gravity circuits aimed at recovering metallic gold into a smeltable concentrate. The presentation will be based on good practice as observed over the years, and damnable mistakes observed and made. The do’s will generally correspond to existing practice in some plants, and these plants will....
