Flotation Process: Extracting Minerals from Ores

The flotation process is a widely used method for separating minerals from their ores. It relies on the differences in surface properties of the minerals to be separated. Here are the steps involved in the flotation process: Grinding: The ore is first crushed into a fine powder through the process of grinding.

Froth Flotation Process

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.

And they're doing that by looking at the fundamentals of flotation. For example, Woodgrove's SFR splits the flotation process into three stages — contacting, separation, and then removal of the froth and tails. Rather than looking at flotation as a macro process, it's being looked at more closely as a micro process.
