Ferrochrome slag is a by-product of ferrochrome alloy production, which is an important component of stainless steel. The total production of ferrochrome slag, which increases significantly every year with the increase in stainless steel production, is more than 1.1-1.5 times higher than the production of ferrochrome metal. In order to conserve natural resources and ensure the sustainable development of the ferrochrome industry, the use of ferrochrome slag in the production of mineral wool should be investigated. In this study, the effects of using different ratios (15-45% by weight) on the formation of fibres in mineral wool production were investigated by morphology of fibres, semi-quantitative analysis, phase analysis, and thermal analysis. It was observed that the morphology of the fibres obtained from briquettes of different compositions with acidity index ranging from 1.78 to 2.21 was more uniform with the use of 5% limestone instead of dolomite, a source of calcium oxide, which decreases the melting temperature and contributes to the basic composition. In this study, fibre formation was obtained with a maximum of 20% ferrochrome slag in basalt limestone composition, while the maximum value of ferrochrome slag in basalt and dolomite composition was up to 45%.
