A GENERAL OVERVIEW OF PUMICE MINING

Within this paper, pumice is investigated in general and its importance is emphasized for our county's economy. Pumice which has a hardness of 5-6 with a specific gravity of 1-2 g/cm 3 owns many pores from micro to microscale. Its heat and sound insulation is extremely high whereas its permeability is too low due to its pore's independence from each other. It has got wide use areas in industry today due to those vital physical properties. Pumice which is produced by very simple mining and processing methods, has been used in many different fields, such as construction, textile, chemical and agricultural industries. This work aims to reveal scientific, technical and statistical information about pumice whose importance has been increasing day by day for our country's economy as an industrial mineral and try to raise the common interests of both industrialists and scientists about its mining and processing
