Vermiculite
Perlite production began after World War II; ... This process is termed "exfoliation." As a result, expanded vermiculite consists of accordion-shaped granules that are lightweight and exhibit high porosity (Kipp et al., 2000). Vermiculite is used as a propagation medium and as a component of potting soil mixtures (Pill and Lambeth, 1975).

Beneficiation – Anglo American South Africa
Beneficiation is the transformation of a mineral, or a combination of minerals, into a higher-value product, which can either be consumed locally or exported. ... In addition, AASA looks for opportunities to transform mining and industrial process by-products into commercially-viable resources. Challenges and actions.
Beneficiation (Metallurgy)
A schematic of the beneficiation process used is shown in Figure 10.16. Figure 10.16. Schematic of the Arrium low-grade beneficiation plants at the Iron Baron and Iron Duke mines. Modified from Stanton and Bannear (2013). Technical comparisons are often drawn between jigging and DMS as alternative methods for iron ore beneficiation.
