    Classification of dimension stone wastes
    (Springer Heidelberg, 2012) Karaca, Zeki; Pekin, Abdulkerim; Deliormanli, Ahmet Hamdi
    For countries in which the stone industry is well developed, opposition to quarry and plant waste is gradually increasing. The primary step for waste control and environmental management is to define the problem of concern. In this study, natural building stone wastes were classified for the first time in the literature. Following on-site physical observations and research at more than 50 quarries and 20 plants, stone wastes were classified as (1) solid, (2) dust and (3) semi-slurry, slurry and cake. As a result of this study, the characteristics of wastes, their main environmental threats and the industries in which wastes could be used were defined for each group.

    The Relationship Between Mineral Content and Flocculant Characteristics for Slurry Waste Water Recycling at Marble Processing Plants
    (Springer Heidelberg, 2016) Bayel, Diler Katircioglu; Karaca, Zeki; Onen, Vildan; Deliormanli, Ahmet Hamdi
    The requirements for clean water in marble processing are partially realized by treating and recycling slurry wastes from the cutting and processing plant. In this study, the flocculation of calcitic and dolomitic (21.2 % MgO) marble wastes was investigated using six flocculants with different molecular weights and anionic levels. Nine solutions between 0.1 and 2.5 mg/L were prepared, and marble waste samples were treated in natural, slightly acidic, and alkaline media. The anionic flocculants had a more dramatic effect on the slower-settling dolomitic marble than the calcitic marble. Calcite precipitation was better in an alkaline medium, while dolomitic marble precipitation was better at a slightly acidic pH of 6.
