Answer Details
Flotation is a process used to separate minerals from their ores. In this process, the ores are treated with a chemical reagent and air, which causes the minerals to be selectively attached to bubbles that float to the surface of the mixture. The minerals that are commonly concentrated by flotation are those that contain sulfide ores, such as copper, lead, and zinc ores. Therefore, the correct option from the given choices is "sulfide ores."
