Micro-structural and mineral methods were performed to analyze the changes of concrete samples after immersion. Results indicate that the corrosion process of cast-in-situ concrete is much faster than the degradation of precast concrete. Chemical attack is the main cause of degradation for both precast and cast-in-situ concrete.

What is beneficiation in mineral processing

Processing operations, which are subjected to a processing plant mountain mass, are divided into basic (own enrichment); preparatory and auxiliary. All existing enrichment methods are based on differences in the physical or physical and chemical properties of individual components of the minerals.

Potash Refining

The Sylvinite ores mined in conventional mines contain Sylvite (20 to 30% K2O), Halite, sometimes Carnallite and 1 to 5% insol. Liberation, in some cases, is substantial at 1 cm (3/8 inch), and virtually complete in all cases at 14 mesh. The separation processes include dissolution of the Carnallite, and removal of the insols, followed by mechanical separation of Sylvite from the Halite ...

Once a suitably sized deposit of a mineral has been found, mining can begin. In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas.
