Rock fibres are made from a melt formed from a blend of low and high halogen waste materials. 80 to 98% are low halogen materials (containing less than 0.5 wt. % halogen) and 2 to 20% are high halogen materials (containing at least 1 wt. % halogen).
1. A process for forming rock fibres comprising melting mineral solids and forming a melt containing calcium, magnesium and iron in a combined amount of more than 15% by weight of oxides of which at least 1% is iron oxide and forming the fibres from the melt, wherein 80 to 98% by weight of the mineral solids are low halogen mineral materials that each contain below 0.5% by weight halogen and 2 to 20% by weight of the mineral solids are high halogen mineral waste containing at least 1% by weight halogen and in which the melt comprise 0.05% to 2% fluorine....
