· Vermiculite is found in mineral mines in South Africa, China, the, and Brazil. To turn this hard rock mineral into a lightweight pellet, an extreme heat process is required to make it. In the process called exfoliation, vermiculite is heated to between 1,000 and 1,500°F (540 – 810°C). The flakes puff up and expand and look like worms

Moulded shapes bonded with sodium silicate: this process involves the mixing of exfoliated vermiculite with potassium and/or sodium silicate to produce an 'earth damp' mixture. This material is then hydraulically pressed into shape in a mould, and then heat cured at temperatures up to 180 °C for up to 24 hours depending upon the thickness of the board. Boards produced …
Processing of the ore can sometimes lead to the peeling off or "scrolling" of the surface layers at the edges of crystals forming fibres (Chatfield and Lewis 1980). Parallel fracturing and splitting of vermiculite flakes can also lead to the formation of fibre-shaped fragments. Vermiculite scrolls may be very fine (< µm diameter) but the vermiculite fragment fibres tend to be fairly …
Vermiculite is a clay mineral that is generally used for a wide range of applications such as in agricultural, horticultural and construction industries. This is due to its various properties which include high porosity, lightweight, thermo-insulating, non-toxic and good absorption capacity when exfoliated. The objective of this research was to critically evaluate the fundamental interaction
At all the mines currently supplying vermiculite crude ore to processing companies in North America, Europe, and the rest of the world, testing has been done.

Vermiculite is a naturally occurring mineral mined in the United States, Brazil, Argentina, Mexico, South Africa, Zimbabwe, Kenya, Uganda, Egypt, India, Russia, China, Japan and Australia. Vermiculite has a flaky, mica-like structure that is flat and shiny in its natural state and puffed and dull when expanded.
Vermiculite mineral can be beneficiated using several different techniques. Lower-grade vermiculite mineral needs can be met with gravity separation whereas higher-grade vermiculite is primarily achieved using flotation. Flotation can be used to recover vermiculite of varying sizes and a two-stage flotation process can produce a range of grades for specific end uses. Often …
