Optimizing Performance of SABC Comminution Circuit of

This circuit shows a semi-autogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of ‘critical size’ material in the circuit. ‘Critical size’ material, also referred to as pebbles, represents material that does not self-break as readily as other sizes of fractions and therefore would

Grinding Circuit an overview ScienceDirect Topics

Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines Chapter 12). Parallel mill circuits increase circuit flexibility, since individual units can be

PCB Recycling/E-Waste Mt Baker Mining and Metals

A stark difference in gold ore vs. printed circuit boards (PCBs) is that a rich gold ore might have 0.5 1.0 oz of gold per ton of ore, but computer PCBs contain 3 8+ oz gold, 15 20+ oz silver, 500+ lbs copper per ton of boards, plus multiple other base and precious metals. Given the commodity nature of electronics such as computers and cell phones, this makes PCB recycling a great
