Vermiculite, in ore concentrate and exfoliated state, may contain small quantities of crystalline silica, as quartz. This is usually only present as non-respirable particles but mechanical action such as milling may reduce any quartz that may be present to a respirable particle size. Silica is a very abundant material in a variety of forms and
