A typical perlite sample is composed of 71 to 75 percent silicon dioxide, 12.5 to 18.0 percent alumina, 4 to 5 percent potassium oxide, 1 to 4 percent sodium and calcium oxides, and trace amounts of metal oxides. Crude perlite ore is mined, crushed, dried in a rotary dryer, ground, screened, and shipped to expansion plants.

Expansion of the treated perlite ore fines is in the same manner as conventional perlite expansion of the larger normal perlite particles. The perlite ore fines can be expanded by themselves or can be mixed into a common feed with the original standard size perlite feed particles. The examples below will illustrate the process of this invention.

1. Introduction. Perlite is a naturally occurring volcanic siliceous rock which consists mainly of amorphous silica (70–76% wt.) but also contains smaller quantities of numerous other metal oxides (Al 2 O 3, K 2 O, Na 2 O, Fe 2 O 3, CaO, MgO).Perlite can be expanded from 4 to 20 times its original volume when heated at a temperature close to its softening point (700–1260 °C), due to the ...
