The LaRONDE mill in the Abitibi region of Quebec was commissioned in 1988 and has been treating the LaRONDE ore since 2000. The mill has experienced many expansions to accommodate 7,500 tonnes/day (t/d) and recently ramp down to 6,000 t/d since the deep extension began. The process was designed to recover gold, silver and base metals. In 2008, the Goldex plant in the Abitibi region began trucking gold-pyrite concentrate (TCGO) for gold extraction at a treatment plant feeding its pulp to the LaRONDE mill, increasing gold output by 40,000 ounces. In 2009, the high gold grade Lapa ore processing facilities were annexed to the LaRONDE plant, increasing output by 120,000 ounces of gold. This paper outlines the metallurgical highlights, challenges, and future outlook related to the treatment of different ore types.
