Economic and social commission for asia and the pacific regional mineral resources development centre

Becker, Jacques - Nama Orang;

Perlite is a glassy yolcanic roc~which 'fill upon rapid and controlled heating, expand or l:lpop" into a frothy material of low bulk density -valued as a ,lightweight aggregate. Occurrences and commercial• deposits of perli te are known throughout the world as well~exposed flows and domes of Tertiary and Quatern~ry age like most of ~he volcanic rocks of Indonesia are. See map. Simple field and laboratory tests $Uffice to demonstrate if the product is of economic value. Perlite is mined by open pit methods; milling procedures are simple and perlite is processed or "popped" in furnaces. Transpo""ttation of une.xpanded perlite by rail OT truck is a significant economic factor. Because of its physical and chemical properties: low bulk density, low thermal conductivity, high resistance to fire and low sound transmission, uses of expanded perlite are many and varied: aggregate ~nd insulating material in the construction industry (_60 % of the production), loose fill insulation in cavity walls (_tankers, reservoirs), low temperature insulation (_cryogenics), fire proofing, horticul tur_al aggregate, excellent filter (_oil, water) , excellent filler, diluter and carrier of insecticides, herbicides, fertilizers, others uses as extenders in paints, enamels, glazes, plastics, resins rubber, abrasive, etc. Pumice, pumicite and volcanic cinders may be used a$ substitutes. In conclusion it is highly recommended that a preliminary survey should be carried out at the different perlite sites.
