If a regular closed circuit with ball or rod mill and mechanical classifier is to be used, the test charge is given an unfinished grind, removed from the mill and hand classified and the resulting sands returned to the mill for additional grinding. Two or three stages are generally sufficient to approximate a regular closed circuit grind.
