This prevents other carbonaceous materials wood clay etc in the ores from adsorbing the gold first “preg robbing” In this step Mills grind the ore exposing gold particl Water joins the ore to form slurry A trash linear screen rejects wood and debris so that it does not disrupt later operationsSo as water flow is slowed down to catch finer sized gold it is generally necessary to use shorter riffl Half inch mesh screen is commonly used for primary classification in small and medium sized sluicing operations because the screen is large enough to allow classification to take place quickly yet no materials greater than half inch in
