Not all of this experience relates to the gold processing sector but we have no hesitation in suggesting that this experience is directly applicable to gold. However, when processing low specific gravity ores, the effectiveness of fully autogenous grinding will be less and may require the use of steel in the SAG mill. In North America, designers have preferred to focus on large diameter, short ...
