Modified thionocarbamates are used in copper-gold ores, which allow some selectively against iron sulfides even at a pH value less than 10. Many gold plants use a blended collector or separate collectors as needed based on mineralogy and ore chemistry. Copper sulfate is commonly used as an activator of gold-bearing iron sulfides in flotation ...
