A process is described for the preparation of perlite ore fines for expansion. The ore fines are treated with an agglomerating agent which has a viscous liquid phase at a temperature above ambient temperature but below the critical dehydration temperature of the perlite ore fines.

Perlite is formed from a volcanic magma flow of pure alumina silicate glass deposited onto the surface of the earth where the molten glass cools and subsequently hydrates water. The purity of the perlite mineral itself, and the extent to which it is intermingled with pre-existing surface materials, varies considerably from deposit to deposit.

Perlite ore contains between 2% and 5% combined or occluded water. When rapidly heated above a temperature of 1,000 degrees Celcius, the graded perlite ore particles melt and expand to between 4 and 40 times the original volume as the combined water vaporises and forms microscopic cells or tiny bubbles in the heat softened glass.

Perlite mines include perlite, obsidian and turpentine. The principle of perlite is that perlite ore is crushed to form ore sand with a certain particle size. After preheating and roasting, rapid heating, the water in the ore is vaporized, and it expands inside the softened vitreous ore to form a porous structure with a volume expansion of 10 ...

This distinguishing feature which sets Perlite apart from other volcanic siliceous rocks is that when heated above 1000°C, it expands up to twenty times its original size. The expansion is due to the presence of a few % combined water in the crude ore. When processed at proper temperatures, the crude ore pops in a manner similar to popcorn.

Perlite is a naturally occurring siliceous volcanic rock containing two to six per cent combined water. When the crude rock is crushed and heated above 1600° F ( 871° C), the combined water vaporizes and the perlite expands four to twenty times its original volume. This expansion process creates countless cells in the glassy particles, which ...

Imports of processed crude perlite to the United States in 2009 were at the lowest levels since 1997. Greece surpassed the United States in processed perlite production starting in 2003. Perlite is mined in about 35 countries; leading producing countries over the last decade were Armenia, China, Greece, Hungary, Japan, Turkey and the United States.

The expansion process is caused by the presence of water in the crude rock. When perlite ore is rapidly heated to above 850°c this water vaporises and causes the softened rock to expand. Tiny glass-like bubbles are produced which account for the lightweight and exceptional physical properties of expanded perlite. Related products Aquaperl 10KG

Due to the normal open pit type operation of perlite deposits the ore frequently has a high surface moisture content.The surface moisture must be kept very low when it is separated into various sizes for marketing. Often times the surface moisture must be less than half of 1% for effective screening. Screen heating devices are sometimes helpful.
