Документ Briquetting the Carbon Phase from the Sludge Ponds at the Anzhersk Deposit(Allerton Press, Inc., 2013) Sergeev, P. V.; Biletskyi, V. S.The briquetting of coal slurries from the Anzhersk deposit in the Kuznets Basin is investigated. Petroleum binder and sodium lignosulfonate are employed. The solid carbon phase from the sludge ponds (ash content up to 35%) has adequate briquetting properties when petroleum binder is added. The use of sulfite waste liquor at pressures of 80–100 MPa yields mechanically strong briquets that require additional water protection.Документ Derivatography as the method for studying structure of water on solid mineral surface(CRC Press, Taylor & Francis Group, USA, 2012) Biletskyi, V. S.; Shendrik, T. G.; Sergeev, P. V.It is proposed to use derivatographic method for investigation of structure of water film on mineral surface. It allows to identify some kinds of moisture, particularly to differ the film moisture from other water types. For the case of hydrophilic materials this method allows to differ some kinds of film water (probably, with great energy of bond and adhesive water).
