Boosting gold recovery in quartz-hosted ores via flotation can be achieved through the following strategies:
Optimized Grinding and Liberation: Fine grinding of the ore ensures that the gold particles are liberated from the quartz matrix. Quartz-hosted ores tend to require precise control over particle size during grinding to expose the gold for effective interaction with flotation reagents. Over-grinding can lead to sliming and reduced recovery, so optimization is critical.
Appropriate Collector Selection: Using specialized flotation collectors, like xanthates, dithiophosphates, or specific reagent blends designed to enhance the attachment of gold-bearing minerals, improves recovery rates. Collectors tailored to target gold and associated sulfides (e.g., pyrite or arsenopyrite) are particularly effective as gold is often finely disseminated within these minerals.
pH Optimization and Depressants for Quartz: Adjusting the pulp pH during flotation can help enhance gold selectivity while suppressing quartz recovery. In quartz-hosted ores, depressants such as water glass (sodium silicate) or other modifiers are utilized to reduce the flotation of quartz and improve the concentrate grade with higher gold content.
By integrating these strategies, the flotation process can achieve better separation and improved gold recovery from quartz-hosted ores.
