Flotation Optimisers and Depressants

Pionera® F-Range of biopolymers consists of selective depressants and flotation optimisers for a broad range of gangue minerals in mineral beneficiation processes.

They can offer a significant economic advantage in the flotation of minerals by reducing smelter penalties, increasing grades and recovery of mineral concentrates.

Key Benefits:

Improved grade and recovery
Depression of penalty elements
Excellent EHS profile
Non-toxic
Sustainable products from renewable sources

Our flotation depressants are proven to be effective on a variety of gangue minerals:

Sulfide minerals, like pyrite, pyrrhotite, arsenic and bismuth sulfides
Oxide minerals, like silicates, talc and calcite
Clays and graphite
Sulfate minerals, like baryte and gypsum

All You Need to Know About Mineral Processing

Mineral processing is the art and technology of treating ores from mining areas in order to separate the valuable minerals from waste rock. It includes processes to provide a more concentrated material for the procedures of the following extractive metallurgy. The three main processes to increase the concentration of minerals are leaching, flotation and gravity concentration. Recently ore sorting by xrf-technology became increasingly relevant.
