A process of separating fibres from asbestos-bearing material which process comprises the steps by treating said asbestos-bearing material with a chemical agent capable of reacting with, or adsorbing on, asbestos fibres to form a dispersion, and agglomerating said dispersion. The process gives high yields of novel fibres characterized in that the said fibres provide reinforcement in cementitious compositions.
